According to research, there are distinct temperature shifts that occur at various points in the sleep cycle. Reduced body temperature is associated with improved sleep quality, while increased temperatures can disrupt the sleep cycle. Therefore, you may get a more restful night’s sleep on a mattress that is both cool and airy.

Those who tend to overheat in bed may find that switching to a cooling mattress helps them get a more restful night’s sleep. The materials used to make mattresses can have an effect on how well (or poorly) they keep you at a comfortable temperature while you sleep. We use a heat gun to check for heat retention on the mattress’ surface after heating a water bottle to 98.6 degrees Fahrenheit and leaving it on the mattress for 15 minutes as part of our temperature control testing process. We considered not only how well each mattress managed heat and humidity, but also how well it was built and how long it was expected to last when making our recommendations.

The minimum number of nights necessary for a trial is 30, but the total trial length is 100.
Limited Warranty for Fifteen Years
There are a variety of sizes available, including twin, twin XL, full, queen, king, and California king.

This is ideal for:

  • Memory foam hybrids are a great option for sleepers who value both contouring and responsiveness.
  • Those who are prone to headaches and muscle tension often
  • Smokers in bed

Highlights:

  • Memory foam that conforms closely to the body but doesn’t trap heat
  • A sturdy coil system offers solid pillaring and boosts airflow.
  • Soft padding alleviates stress.

Helix Sleep has many memory foam hybrid models that are tailored to different body types and sleeping positions if you’re in the market for a new mattress but aren’t sure what firmness level you prefer. For all its features, the Midnight Luxe stands out as a top pick among the brand’s offerings. The pocketed coil system used in the mattress’s construction allows for constant airflow, keeping sleepers at a pleasant temperature all night long.

Efficiency Rating

Testers did not experience excessive body sinkage thanks to the Midnight Luxe’s transitional layer’s supportive properties. Our team’s side sleepers who experience pressure buildup in the shoulders and hips found this, combined with the conforming memory foam layers, to be an ideal mattress. The pocketed coils not only provide a firm foundation, but also promote consistent airflow, eliminating the heat buildup that can occur with conventional foam layers. The Helix Midnight Luxe slept comfortably cool as a result.

Materials Used

Luxe series hybrids are thicker pillow-top models with additional features to improve your sleep experience, while standard Helix models may appeal to budget-conscious shoppers. Our panel of experts ranked the Midnight Luxe at a (6), making it the middle of the pack choice. The mattress’s plush surface is the result of two layers of memory foam beneath the pillow-top. As a transitional layer, polyfoam offers superior conformability and support. Zoned pocketed coils provide the support core, and high-density foam serves as the foundation.

While the Midnight Luxe and other Luxe hybrids do come with a higher price tag than base Helix models, they are still relatively inexpensive. All 50 states receive free shipping from Helix Sleep. The Midnight Luxe has a 15-year warranty and a sleep trial that lasts for 100 nights.

DreamCloud Mattress

The cost could be between $79 and $1,499.

Classification of the Mattress: Hybrid
Consistency: Six, Medium-Firm

Duration of the Trial Period is One Full Year (30 Night Minimum).
Lifetime Limited Warranty.
Twin, Twin XL, Full, Queen, King, and California King

Who should use it most effectively:

  • Sweltering sleepers
  • Couples
  • Size- and orientation-neutral sleepers

Highlights:

  • An advanced pressure-relieving comfort system made of different types of foam follows the shape of the body to provide maximum support.
  • Having a core that is pocketed makes it easier to circulate air and maintain a consistent temperature.
  • An experiment lasting one year consisting of 365 nights of sleep

The DreamCloud is a foam-hybrid mattress, so it offers the pressure relief and notable contouring of memory foam without the heat trapping issue. As a result of these appealing characteristics, the bed received high marks from our evaluation team.

Analysis of Results

The coil core and medium firm (6) feel of the bed made it comfortable for most of our in-house testers due to its adaptable blend of cushioning and support. The DreamCloud’s versatility in accommodating couples with varying sleeping preferences, in addition to its high level of bounce and edge support, makes it a top pick for shared sleeping arrangements. The bed’s superior build and functionality, in comparison to the typical hybrid model, come at a price that won’t break the bank.

The bed’s individually wrapped coils in the support core allowed for lots of airflow to keep it cool. The comfort system’s gel-infused memory foam layer helps prevent nighttime overheating by dissipating your body’s excess heat.

Components and Construction

In order to create a well-rounded mattress, the DreamCloud combines high-quality foam layers with a supportive coil base. Our reviewers appreciated the plush feel of the cashmere blend used for the cover. Polyfoam has been quilted into the top to provide padding. The polyfoam layer beneath the memory foam promotes further contouring but has a firmer feel to prevent excessive sinkage. The gel-infused memory foam layer below that provides a close, hugging feel during testing. Then, there’s a breathable coil mattress that prevents you from sinking in too far at any point. Therefore, while lying on the DreamCloud, one has the sensation of sleeping both “in” and “on” the bed.

The DreamCloud’s shipping is on the house within the 48 contiguous states, but there is an option to upgrade to faster shipping for an additional fee to Alaska and Hawaii. There is a 30-day break-in period before the 365-night sleep trial begins, adding even more value to the mattress. The bed is backed by a limited lifetime warranty after the trial period ends.

Many heavier sleepers need a mattress that will reinforce their bodies and keep them on an even plane because uneven support and excessive sinkage can exacerbate pain from poor sleep posture. During our testing, the Saatva Classic’s high-end design provided exceptional stability without compromising on either comfort or pressure relief.

A Look at Its Results

The Saatva Classic can be purchased in one of three different firmness levels, allowing you to find the perfect feel for your unique body and sleeping habits. Members of our team who sleep on their sides, particularly those who suffer from shoulder pain while sleeping, found that the soft (3) model was the most comfortable option. For those who needed a little extra contouring, the medium firm (6) setting did the trick. Our heaviest sleepers (over 230 pounds) found the firm (8) feel to be the most supportive. This held true regardless of their preferred sleeping position (on their side, back, or stomach). Saatva allows exchanges for a minimal shipping fee if you decide you made the wrong selection. Both an 11.5-inch and a 14.5-inch mattress height are available to suit individual needs and preferences.

Materials Used

The Classic features a foam and soft-fiber Euro-top and a dense memory foam pad for lumbar support. Thicker bonnell coils made from recycled steel form the support core, while pocketed minicoils serve as the transitional layer. The dual coil layers gave us great edge support and made it much simpler to get into and out of bed. Our beta testers were kept cool and comfortable thanks to the high-quality airflow generated by both coil layers.

White Glove delivery is free for all Saatva customers in the 48 contiguous states. This service includes in-home setup and disposal of your old mattress. Most online mattress retailers, on the other hand, charge a hefty sum of at least $100 for this service. There is a 365-night trial period and a lifetime guarantee with your purchase.

WinkBed

One can expect to pay anywhere from $1,149 to $2,049

Innerspring Mattresses
Medium-Soft (4), Medium-Firm (6), Firm (7), and Firm (8)

Minimum 30 night trial, with a maximum of 120.
A Limited Lifetime Warranty is Provided.
Sizes available include: Twin, Twin XL, Full, Queen, King, and California King

For those who:

  • Individuals who sleep on their sides or backs
  • Sexy snoozers
  • Couples

Highlights:

  • The foam contours to the shape of the body, helping to correct posture and relieve stress on the spine.
  • The perimeter is safeguarded by zoned coils, and it’s easy to move around the floor.
  • The mattress is kept comfortably cool by its breathable Tencel cover and robust internal airflow.

Side sleepers often have trouble finding a comfortable and cooling mattress. People who sleep in this position frequently need an adaptable mattress that encourages proper spinal alignment and provides ample padding for the hips and shoulders to alleviate the pressure points that develop there. The WinkBed is a good middle ground for side sleepers looking for a cool, comfortable, and supportive mattress due to its combination of foam layers and breathable components.

Exactly How Well It Worked

The WinkBed was the only mattress we looked at that managed to be both comfortable and long-lasting. The coils provided a sturdy support system, and the foam layers contoured to the bodies of our testers without letting them sink too far in. Since there are various levels of firmness available, members of our testing team of varying sizes were able to find a model that met their needs.

The WinkBed also outperformed competing hybrids when it came to isolating motion. The outer layers were able to dampen motion well, and the coils didn’t generate much response. The zoned coil system made the edges feel safe, and none of us sunk too deeply when walking across it. Our temperature testing also found that the WinkBed’s Tencel cover was effective at wicking away moisture and the coils were able to maintain a steady airflow, so the bed received high marks overall.

Elements That Comprise It

The WinkBed comes in four different firmness options: medium soft (4), medium firm (6), firm (7), and firm (8) for the WinkBed Plus. The base of all WinkBed models is a layer of polyfoam, quilted into the cover; the medium soft, medium firm, and firm models all have an additional polyfoam layer. Instead of a second polyfoam layer, the Plus uses a zoned latex layer. The quilted polyfoam gently conformed to our bodies, allowing for more even weight distribution and less pressure points to form. The layer of transitional polyfoam between your body and the support core offers moderate cushioning and separation. The polyfoam padding in the medium soft version is doubled up.

The WinkBed is a hybrid design that provides support through pocketed coils. These coils are free to pivot without affecting one another, providing a solid foundation without excessive motion. Our bed testers appreciated the added perimeter support, which reduced sinkage when getting in and out of bed.

There is no cost for ground shipping within the 48 contiguous states when you order a WinkBed, and you can sleep on it for an entire 120 days without any commitment. We confidently stand behind the quality of our WinkBed mattresses with a lifetime guarantee.

Brooklyn Bedding Aurora Luxe

From $999 to $2,249

Hybrid Mattress
Medium soft (4), medium firm (6), and firm (7)

Duration of the Trial: 120 Nights (30 Night Minimum)
Limited 10-Year Warranty
Available in various sizes including Twin, Twin XL, Full, Queen, King, California King, and Custom

To whom it will be of greatest benefit:

  • Sleeping on one’s side or back
  • The hot-blooded
  • People whose blood pressure rises during sleep

Highlights:

  • There are three levels of firmness to choose from.
  • The pocketed coil support core allows air to flow freely, preventing overheating.
  • Foam padding reduces noise and vibration.

While everyone has a different idea of what makes a good mattress, some models are made to appeal to a wide variety of sleepers. The Aurora Luxe from Brooklyn Bedding fits the bill. The hot sleepers on our team really appreciated the cooling features of the Aurora Luxe, and the mattress comes in three firmness levels to accommodate all types of sleepers.

Performance Analysis

In terms of comfort, the Aurora Luxe hits the sweet spot between being pliant enough to relieve pressure points and firm enough to prevent the mattress from sagging. In our pressure relief tests, all three firmness levels performed exceptionally well, which is especially significant for side and back sleepers. The medium-soft mattress was the best choice for those weighing less than 130 pounds, while the firm mattress was the most accommodating for those weighing more than 230 pounds. Depending on how you like to sleep, the medium-firm option should be comfortable for people of varying body types and sizes.

TitanCool, a phase change material, is infused into both the cover fabric and the CopperFlex foam to help with moisture wicking, heat dissipation, and temperature regulation. The coils allow air to flow, which helps to keep the bed at a comfortable temperature.

Materials Used

There are three firmness levels to choose from when shopping for an Aurora Luxe: medium (level 4), medium-firm (level 6), and firm (level 7). The CopperFlex foam that is at the top of all of the options is a standard feature. We found that this foam molded to our bodies while still providing a touch of responsiveness. After that, you’ll find a layer of TitanFlex foam, which is noticeably more supportive. The firm model uses TitanFlex foam for increased support, while the medium-soft and medium-firm variants feature a layer of gel-infused memory foam between these two layers. The pocketed coils in the support core of all of the available firmness levels are strategically placed to provide additional back and tummy support.

Within the 48 contiguous states, Brooklyn Bedding offers free shipping. After the initial 30-day break-in period, customers can return their mattresses for free during the 120-day sleep trial. A ten-year warranty protects your investment in the bed.

Best Cooling Mattresses for Hot Sleepers (2023) | Sleepopolis

Results Obtained

When our test subjects laid down on the bed, the top layer of memory foam contoured closely to their bodies, providing excellent pressure relief. Our motion isolation tests also gave the foam high marks, making this a good choice for anyone who finds that their partner’s movements keep them awake. When compared to other all-foam beds we tested, the denser polyfoam layers provided sufficient reinforcement. Because they prefer a softer shoulder and hip area but still need their lower back supported, the side sleepers on our team appreciated the mattress’s medium level of contouring.

Material Composition

The mattress has been rated as medium firm by our sleep experts and measures 14 inches thick with an all-foam construction. Copper fibers are quilted into the cover to help disperse body heat. To help with this, the base of the mattress is comprised of four inches of memory foam that has been treated with cooling gel and phase change material. The 9-inch base layer of high-density polyfoam serves to stabilize the mattress and is followed by a 1-inch layer of firmer transitional polyfoam.

Orders of Nectar shipped within the 48 contiguous states are delivered at no cost to the customer. The lifetime guarantee and 365-night sleep trial are great bonuses for this mattress.

Leesa Sapira Hybrid

Ranging from $1,349 to $2,299

Hybrid Mattress
Consistency: Six, Medium-Firm

Duration of the Trial: One Hundred Nights (30 Night Minimum)
Limited Guarantee for a Period of Ten Years
Included sizes are Twin, Twin XL, Full, Queen, King, and California King.

Target Audience:

  • Interchangeable bed/sleepwear
  • Warm snoozers
  • Sex-loving couples who place a premium on mutual response

Highlights:

  • Pressure points are effectively relieved by the foam comfort system.
  • Reduced heat retention thanks to a coil ventilation system
  • Deliveries are made at no cost to the customer in all 50 states.

The Leesa Sapira Hybrid is a high-quality mattress that features a high-density foam comfort layer, a gel memory foam core, and a coil system for a lot of support. This symmetrical texture satisfied many of our testers regardless of their weight or how they prefer to sleep.

Evaluation of Results

Our side and back sleepers, who tend to develop painful pressure points in the shoulders, hips, and spine, benefited greatly from the cushioning provided by the mattress’s various layers of foam. In the meantime, the coil system and polyfoam transitional layer provided sufficient support to prevent our lower backs from sinking. If you weigh less than 230 pounds, the mattress should be fine, but anyone over that might feel too heavy for it.

Our movement was less restricted than it would have been on a purely memory foam comfort layer, likely due to polyfoam’s slightly higher responsiveness compared to memory foam. Along with the springy coils, this is what makes the bed so ideal for intimate activities. Air circulating through the coils helped keep the mattress at a reasonable temperature during the test period. There was barely any surface heating detected by our heat guns.

What Components It Has

A layer of polyfoam, which conforms to the body but is slightly more responsive than memory foam, lies beneath the cover of the mattress, which is made from a polyester blend. The deeper conformity of the memory foam layer beneath the surface helps to alleviate pressure points. The next layer is a thick polyfoam that acts as a buoyancy aid. Pocketed coils with a reinforced perimeter make up the support core. The coils in the mattress provide support and a little bit of bounce.

Leesa offers a 100-night sleep trial to potential buyers. After a 30-day trial period, returns made within this window will be refunded in full. It’s free to ship to any state in the union, and it comes with a warranty that lasts 10 years on the bed.

Bear Hybrid

The cost can vary between $1248 and $2998.

Synthetic-Flexible Mattresses
firmness level 6 (medium-firm)

Duration of Trial: 120 Nights (including a 30-Night “Break-In” Period)
A warranty that lasts forever
We carry all of the most common sizes, including Twin, Twin XL, Full, Queen, King, and California King.

Who can benefit the most:

  • People who get hot while they sleep
  • Tourists in search of a lengthy free trial of sleep aids
  • Ones who sleep on their sides or backs

Highlights:

  • Fabricated with a proprietary cooling fiber cover and gel-infused polyfoam, these cushions are made to efficiently vent your body’s excess heat.
  • Conspicuous contouring without excessive sinkage characterizes the mid-range, medium-firm (6) feel.
  • Free overnight shipping and a lifetime guarantee are included in this 120-night trial.

The Bear Hybrid has the best temperature regulation of any of the beds we tested, especially when compared to those that use foam in the mattress’s comfort layer. This is because of the combination of our patented cooling technology, airy materials, and a well-ventilated structural core.

Evaluation of Results

Participants weighing between 130 and 230 pounds who prefer to sleep on their sides found the medium firm (6) feel and thick comfort layers to be the most accommodating. Members of our team weighing less than 130 pounds found adequate support lying on their backs or bellies while sleeping on the mattress’s medium firmness.

Airflow through the pocketed coils and the cooling cover kept the Bear Hybrid cool during testing. When worn, Celliant converts the body’s heat into infrared energy, which helps maintain a comfortable temperature and speeds up the recovery of tired muscles. The top layer’s gel infusion is designed to do double duty by cooling the wearer down and keeping moisture out. The pocketed coils give the mattress extra bounce, making it a popular choice for couples because of the bouncy feel it provides during sex. The thicker comfort layers muffled noise, and the responsive surface made it easy for testers to move around on the bed.

Materials Used

The 14-inch bed has a cover made from a special combination of Celliant and polyester. Next, our reviewers appreciated the softness of the quilted cover and the layer of gel-infused polyfoam inside. Following this is a layer of polyfoam that can be molded to specific pressure points. Our research showed this to be an efficient method of releasing tension.

Cushioning between the comfort system and the coil support core is provided by a third polyfoam layer. Polyfoam prevented our test subjects from sinking in and distributed their weight in a way that supported proper posture. The 8-inch pocketed coils in the support core are free to pivot in their own space to conform to the contours of your body and offer localized, zoned support to your shoulders and hips. The polyfoam base ensures the support core doesn’t move around too much.

Mattresses purchased from Bear come with a 120-night sleep trial and a lifetime warranty, and their prices are competitive with those of similar hybrids on the market.

Nolah Evolution 15

Amounting to between $1,599 and $2,499

Hybrid mattresses are a newer and more comfortable option.
Medium (5), Medium-Firm (6, 8), and Firm (10).

The duration of the trial is 30 nights minimum, but a total of 120.
A Limited Lifetime Warranty is Provided.
Available in Twin, Twin XL, Full, Queen, King, and Cal King

That would benefit the most from it:

  • Adherents to the side sleeping position
  • Those who suffer from nighttime pressure buildup
  • Sweltering sleepers

Highlights:

  • The foam quilting on the Euro-top makes it very soft.
  • The pocketed coil support core is divided into zones to give your core the support it needs.
  • the 15-inch profile

A hybrid, like the Nolah Evolution 15, combines the responsiveness of foam with the durability of a coil system to create a comfortable and supportive sleep surface. The end result is a mattress that scored exceptionally well in our pressure relief tests, making it a good option for those who suffer from nighttime pain due to their back or elsewhere.

Its Results

Individuals who tend to overheat while sleeping praised the Evolution 15. The coil system allows air to circulate, and the foam layers are designed to dissipate heat. The bed can be adjusted to three different levels of firmness to accommodate different sleeping styles. In terms of firmness, our team’s medium-five and medium-six sleepers favored the plush and luxury firm options. Since stomach sleeping requires a flat, supportive surface to ensure proper spinal alignment, those who prefer to sleep on their stomachs found the firm (8) option to be ideal.

Substances Used in Its Construction

The Nolah Evolution 15 is a thick mattress with an adjustable support system, measuring in at 15 inches. For added comfort, a layer of our exclusive AirFoamICE foam sits beneath the quilted Euro top cover. In the opinion of our sleep experts, the bed’s two comfort layers provided above-average cushioning for a hybrid when lying on it. The next layer is a firmer polyfoam, which not only acts as a moderate contour but also as a cushion between you and the support core. It has an 8-inch pocketed coil system beneath the foam, which distributes your weight evenly and provides localized support.

Within the 48 contiguous states, Nolah offers free shipping on all mattresses. After the initial 30 days, customers are welcome to return their bed for a full refund, making the total trial period 120 nights. We’re so confident in the quality of the Evolution 15 that we’re offering a lifetime guarantee on it.

Birch Mattress

The cost can vary between $1,349 and $2,099

Hybrid Beds and Mattresses
Firmness Level 6 (Medium Firm)

Duration of the Trial: One Hundred Nights (30 Night Minimum).
Limited 25-Year Warranty
Twin, Twin XL, Full, Queen, King, and California King

In what situations does it work best:

  • Consumers who are concerned about the environment
  • We cater to both side and back sleepers
  • Those whose bodies heat up excessively while they rest

Highlights:

  • Natural materials like cotton and latex provide breathability, which is important for maintaining a comfortable body temperature.
  • The Talalay latex comfort system does a wonderful job of cradling the body and releasing tension.
  • One hundred night test of sleep quality

The Birch Mattress is a hybrid bed that is crafted from natural, high-quality materials. The mattress, which we rated as a “medium firm” six, provided exceptional support for our sleepers and a satisfying level of responsiveness for those who prefer a compromise between the two.

The Results

Those of us who prefer to sleep on our sides found the Birch to be an excellent option because it adequately supported our lower backs and hips while providing ample cushioning for our shoulders and hips. Those of us who sleep on our backs appreciated the mattress’s combination of firmness and softness. The breathable latex should keep you cool and comfortable even if you tend to sweat excessively while sleeping. Because of the coil core’s open design, air can flow through the bed and keep you cool during the night. If you value mobility across the bed, this is a fantastic option. People who like to sleep “on” the bed as opposed to “in” it should also enjoy the buoyant surface.

Materials Used

During testing, the Talalay latex used in the Birch Mattress’ construction cushioned pressure points while also providing adequate pushback to limit mattress sinkage. A strong and long-lasting foundation is provided by pocketed steel coils. There is a layer of wool on top of the bed, which we found to be very plush, and a layer of wool and rayon below it that serves as a fire barrier. A cover made of certified organic cotton from the Global Organic Textile Standard is on the bed. If you’re looking for a mattress with verified organic sourcing, this is a great option because the latex is certified by the Global Organic Latex Standard.

Regardless of where you live in the United States, Birch will ship your order to you for free. There is a 25-year guarantee and a 100-night sleep trial on the bed, but returns on mattresses are not accepted until after the initial break-in period of 30 days has passed.

How to Find a Cooling Mattress

There are a lot of factors to think about when shopping for a mattress, and this is especially true when trying to find a mattress that will keep you cool while you sleep. Due to the wide variety of cooling mattresses available, it is important to understand the role that certain features play in a mattress’ ability to regulate body temperature.

Keep reading to find out everything there is to know about mattresses, including how much they cost, what kinds there are, what kinds of materials they are made of, and how your sleeping position can make a difference.

What is a Cooling Mattress?

Having trouble getting comfortable at bedtime or waking up in the middle of the night because they’re hot and sweaty is a common problem. This is a problem that can be made worse by some mattresses and made better by others. If you tend to get hot during the night, you may want to look into a cooling mattress.

Many mattress companies advertise their products as “cooling mattresses,” meaning that their designs incorporate features that keep sleepers from overheating during the night. After putting hundreds of mattresses through our rigorous testing process, we can attest to the many ways in which the right mattress can keep you cool during the night. There is no specific mattress feature or system to which the term “cooling mattress” refers.

What to Look for in a Mattress

Mattress-Survey-Graphic_Desktop

Finding a mattress that keeps you cool may be your top priority, but there are other factors to think about as well. Having a mattress that is able to keep you cool is great, but it won’t be of much use if it causes you discomfort or is too expensive.

Companies selling mattresses have a lot of leeway to use hyperbolic language and make grand claims about their products. Don’t be fooled by flashy copywriting; instead, focus on the actual features of the mattress and whether or not they’re important to you in making your buying decision.

  • Value for Money: You can find cooling mattresses in a wide price range. The quality of the materials used to make a mattress can greatly affect its final cost. Some high-quality mattresses can be found at reasonable prices, despite the fact that those made from more durable materials tend to be more expensive overall. Since the manufacturer doesn’t have to shell out money for showrooms and extra staff when selling directly to consumers through online platforms, the mattresses can be found at much lower prices. The quality and durability of these “mattress in a box” options are on par with what you’d find in traditional mattress shops.
  • Which mattress type and firmness level is best for you depends on your sleeping position. It’s common knowledge that people who sleep on their sides favor mattresses that are softer in order to better support their hips and shoulders. Mattresses that are sufficiently firm to support the lumbar region are often preferred by back sleepers. The degree to which you feel a mattress is soft or firm depends, naturally, on your own body weight.
  • In terms of mattresses, you can choose from a wide variety of options, such as all-foam, innerspring, hybrid (a combination of coils and other materials), airbed, and latex. Compared to foam mattresses, our heat-mapping tests found that innerspring and hybrid mattresses were more comfortable because of the airflow through their coil layers. Body heat is easily retained in the memory foam comfort layer of a mattress, whether it is an all-foam mattress or a hybrid.
  • A mattress’s contouring ability, also known as its conforming ability, describes how well it “hugs” the body. Since it conforms so well to the body, memory foam also has a penchant for keeping in heat. Unfortunately, many of the mattresses that are designed to keep you cool don’t offer much in the way of body contouring. As an example, innersprings provide a more temperature-neutral and responsive feel.
  • Material Quality There is a wide range of mattress materials available, and each has its own quality standards. Most polyfoams improve in quality as their density increases. The polyfoam in a better mattress will last longer and won’t show body impressions as easily. In general, the quality of natural latex exceeds that of synthetic latex.
  • Level of Firmness: Beds can be anywhere from the least firm (a 1) to the most firm (a 10) on the firmness scale. The ability of a mattress to stay cool has little to do with how firm it is. Mattresses with a firmness level between 4.5 and 6.5 are the most popular, though some people, especially those who weigh more, may prefer a firmer bed.
  • When a mattress is good at relieving pressure, the weight of the sleeper is distributed evenly across its surface. When pressure relief is subpar, the sleeper experiences painful or bothersome hotspots where the pressure is highest. Our research shows that pressure points are more likely to form on mattresses that are either too firm or allow too much sinkage.
  • When a person sits or lies on the edge of a mattress, edge support is the degree to which that person is supported by the mattress. When a mattress has solid edge support, it allows sleepers to make use of the entire surface area without worrying that they will roll off. Accessing the comfort of one’s bed is simplified by sturdy edge support.
  • Overheating is prevented by cooling mattresses, which are also excellent at maintaining a comfortable temperature. All of the layers in a mattress can help keep things cool. Air can flow freely between the layers of a mattress with coils, keeping you cool. Alternate methods of controlling temperature include the use of specialized cover fabrics and the incorporation of foam comfort layer infusions.
124_LaylaHybrid_HEATGUN-scaled.jpg
In order to determine how much heat a mattress retains, the tester employs a heat gun.
  • When people get on them or move around at night, some mattresses make a lot of noise. We found that all-foam mattresses were the quietest out of all the beds we tested. The coil layers in hybrid and innerspring mattresses tend to result in louder sleep surfaces. However, pocketed coils that are individually encased are much quieter than innerspring.

The Cooling Ability of Different Types of Mattresses

In today’s market, you can buy a variety of mattresses that cater to different needs. There is a wide range in how well various mattress materials can maintain a comfortable sleeping temperature throughout the night. As a rule, mattresses in the same category have very similar construction and functionality.

Even within the different categories of mattresses, there is a wide range of options to choose from. The effectiveness of a mattress for you will depend on its quality of materials, construction methods, and additional features.

Hybrid

A hybrid mattress, by definition, incorporates features of different mattresses. Hybrid mattresses typically consist of a pocketed coil support core and polyfoam, latex, or a combination of these for the comfort layer. A hybrid mattress’s feel can change drastically based on the materials and thickness of its comfort layers.

Particularly helpful for keeping cool while you sleep, a hybrid mattress’ coil support core allows air to circulate freely throughout the mattress. Because of this, most hybrids are comfortable in a wide range of temperatures. Our laboratory studies on mattresses show that adding a layer of latex to the top can further improve cooling, while a layer of memory foam on top can make a hybrid mattress too warm to sleep on.

Foam

Foam mattresses, also known as all-foam or mixed-foam mattresses, are characterized by the use of different kinds of polyfoam for the construction of the mattress’s core support and comfort layers. Some people find that foam mattresses “hug” their bodies more comfortably than others, and this is why they prefer them. Pressure and discomfort can be reduced thanks to memory foam’s conforming qualities.

In order to combat the fact that foam mattresses tend to hold in heat, manufacturers frequently incorporate cooling materials into their designs. Phase change material blankets, for instance, are able to convert the heat your body emits into a more comfortable state. Various cooling ingredients like gel, copper, graphite, and charcoal are infused into polyfoam padding for added comfort.

Innerspring

Comfort layers of polyfoam, latex, or some other material sit atop an innerspring mattress’ definitional “coil support core.” Unlike hybrid mattresses, the support core of a traditional mattress takes up most of the space in a traditional mattress. For this reason, our sleep experts have found that innerspring mattresses tend to be more buoyant and less conforming than their foam counterparts.

The airflow between the layers of an innerspring mattress is one reason why these beds are more comfortable in the heat. Since the layers of memory foam in an innerspring mattress are so thin, the mattress still sleeps cool. On the other hand, hybrid and all-foam mattresses are more expensive than traditional innerspring mattresses.

Latex

Latex, which is derived from the sap of rubber trees, is used to make mattresses more comfortable and pliable by adding springs. There are latex mattresses that only have a latex comfort layer and a latex support core. Some mattresses have latex layers on top of other materials like coils or polyfoam.

In particular, latex has inherent cooling properties. Perforating or aerating the layers of a latex mattress is a common practice among manufacturers. With the latex layer between them, body heat is dispersed and the sleeper stays cool as air flows through. When compared to Dunlop latex, Talalay latex is more temperature neutral; however, both types can be aerated.

Airbed

Simply put, airbeds are mattresses that feature built-in air chambers that can be inflated or deflated to adjust the mattress’s level of firmness. Couples may appreciate airbeds that offer adjustable firmness on both sides. It should be made clear that the term “airbed” refers to a mattress designed for permanent use and not the inflatable mattresses commonly used for camping or short-term travel.

The air chambers in most airbeds provide natural cooling, making them a popular option for warm sleepers. We have found that some airbeds can lose heat too quickly. Thicker comfort layers on airbeds are less likely to have this issue.

Cooling Mattress Materials

Many different materials can be used to make a mattress. While some help keep you cool and comfortable while sleeping, others keep the heat in. Those who tend to overheat during the night should know what features to look for in a mattress in order to make an informed decision.

Principal Components of Cooling Systems

  • The support core of a mattress consists of coils and springs, which are typically made of steel. Since there is so much room between each layer, air can easily circulate and keep the top comfort layers from getting too hot.
  • The effectiveness of gel-infused foam is debatable, but some manufacturers add gel to the comfort layers of memory foam. Those who have trouble keeping cool at night should consider more than just whether or not the memory foam layers contain gel.
  • Standard memory foam is typically made from polyurethane. In response to body heat, it expands to hug the wearer. Simple memory foam has a high heat retention rate, which can make it uncomfortable for warm sleepers.
  • Memory foam has come a long way since its inception; thanks to the efforts of scientists, modern versions are cooler and more breathable. Their efforts have resulted in high-tech memory foam, which may have a cooling pattern of small holes or beads infused with gel.
  • Polyurethane foam, the kind used to make mattresses and pillows, also has the same heat-trapping properties as memory foam. You can use regular polyfoam as a core support or a comfort layer, depending on your needs. In contrast to memory foam, it has much less give.
  • Upgraded from standard polyfoam, advanced polyfoam (also known as open-cell polyfoam) offers superior insulation. Small cells or air bubbles in this modern polyfoam improve breathability and lower heat retention. Modern polyfoams used in mattresses are more temperature neutral.

The Ideal Sleeping Environment for Hot Sleepers

The temperature at which you sleep depends on more than just your mattress. Rather, think about the totality of your bedroom. Your mattress and other sleep accessories can have a significant impact on your ability to maintain a comfortable body temperature while you sleep.

Finding your body’s optimal temperature for sleep is one way to improve the quality of your sleep. The next step is to select bedding that will aid in keeping you cool all night long.

What is the Best Temperature for Sleep?

There isn’t a “best” temperature for sleeping that applies to everyone. Most adults, according to sleep experts, do best at a temperature of about 65 degrees Fahrenheit. Numerous people deviate from the norm, that much is obvious.

Others may find that they need a cooler bedroom because they tend to overheat during the night, while still others may find that they sleep better in a warmer environment. A person can try out various temperatures while sleeping to find the optimal one.

Sheets

Sheet sets can make a big difference in how hot or cold you stay during the night. Flannel, fleece, and thick cotton are just a few examples of insulating and warm-keeping sheet materials. People who tend to get hot during the night shouldn’t use these sheets.

Lightweight cotton, linen, and Tencel lyocell sheets are cooler than other sheet materials. Cotton bed sheets are known to be the most breathable option. They are commonly found in two different weaves: percale and sateen. Percale is a crisper fabric than sateen, but both are known for their breathability.

While linen has a reputation for being a cool fabric, we’ve found that it can be quite rough. This is why many companies opt to pre-soften linen sheets or make a linen-cotton blend. Tencel lyocell, derived from wood pulp, is a fiber with inherent moisture-wicking and cooling properties. Most lyocell sheets that claim to be made from bamboo are actually made from a different plant.

Synthetic cooling materials like Coolmax fabric and Outlast fibers can be found in some cooling sheets. The polyester used to make Coolmax fabric is highly effective at wicking away moisture while still allowing air to circulate. Outlast fibers are a phase change material that can be woven with other fibers to maintain a comfortable temperature.

Pillows

You can find a wide variety of breathable pillows that provide cooling comfort today. A cooling pillow made of memory foam or latex may be the most comfortable option if a standard down or polyester pillow is too hot. Memory foam and latex pillows can be made more comfortable for those who prefer a cooler sleep surface by having them aerated to increase airflow, or by having gel or other cooling materials infused into the foam or latex.
In addition, there are cooling pillows available, which contain air or water chambers to help you stay cool while you sleep. Most of the time, these are more costly, but they deliver the goods.

Blankets

It’s possible to find a blanket that either warms or cools you off. Wool, down, fleece, cashmere, and heavy cotton blankets are the toastiest, so hot sleepers should look elsewhere.

More heat is retained by heavier, thicker blankets, so the opposite is true: lighter, thinner blankets are cooler. Lightweight materials like cotton, cotton blends, Tencel lyocell, and linen are popular choices for naturally breathable and cool blankets. These materials are all breathable and won’t keep your body heat in as much as other options would.

The Coolmax and 37.5 technologies found in some blankets are designed to actively cool the user. The 37.5 fabric is made to keep you at a comfortable temperature, while the Coolmax fabric wicks away sweat and keeps you dry.

Mattress Toppers

A mattress topper may provide some relief from excessive heat while you wait to replace your mattress. When added to a mattress, a topper can alter the way it feels. There is a wide variety of thicknesses and materials available for use as a mattress topper.

In our research, we found that memory foam mattress toppers were the most likely to cause overheating. If they are not ventilated and infused with gel, charcoal, or something else to keep you cool while you sleep, they are not the best option. As an analogy, down mattress toppers have the same insulating properties.

Mattress toppers that are designed to keep you cool can range from those made of naturally breathable wool to those that use cooling technologies like phase change material.

FAQs

Which mattress materials allow for the most comfortable night of cool rest? Repeatedly, our research has found that innerspring mattresses sleep the coolest, followed by latex and hybrid beds. Foam mattresses are the most comfortable and warm. Temperature regulation varies greatly between mattresses for a variety of reasons, the most significant of which is usually airflow.

While the coils in both innerspring and hybrid mattresses allow for plenty of air circulation, we prefer the slightly warmer temperature of a hybrid’s foam comfort system. Foam does not allow airflow and, due to its shape, often contours closely to the body, reducing airflow even at the surface. This makes foam mattresses the warmest option. Although latex has poor ventilation, it naturally retains less heat than synthetic foam, which is an important factor. Mattresses, however, are typically constructed to reduce these effects.

Those who tend to sleep hot may find that a standard foam mattress is too toasty, but there are beds available with special design elements that work to reduce heat retention and increase airflow. The temperature of a mattress is affected by several factors, the most prominent of which is the mattress type.

To what extent can a mattress be cooled? If you’re not in the market for a new mattress but still want to sleep cooler, you can buy a cooling mattress pad or switch to lighter, more breathable sheets. Mattress toppers designed to keep you cool come in a wide variety of forms, from those made of naturally breathable materials to those powered by water.

There is a wide range in price from cheap cooling pads to luxury toppers, but even the most reasonably priced option can make for much more restful sleep. If you tend to get hot during the night, it’s important to make sure your sheets are made of a breathable material that wicks moisture away from the body.

What is the truth about cooling mattresses? Nowadays, there is a trend toward mattresses made from materials that allow for more airflow and less heat retention. However, we have found that different cooling mattresses have varying degrees of breathability and temperature control.

Based on our research and experience, latex hybrid mattresses provide the most comfortable and cool night’s sleep. These mattresses’ latex is often perforated to allow air to flow near the surface and prevent overheating. These mattresses’ support cores, which are made up of coil systems, also create a good deal of airflow. Natural, breathable materials like organic cotton or wool are commonly used for the covers of latex hybrids.

You may also enjoy a cooler night’s sleep on an all-latex mattress. Many of these mattresses feature ventilated layers and breathable cover materials to compensate for the lack of airflow afforded by the solid latex in their support cores. Similarly, airbeds, which have movable air chambers in their support cores, offer above-average temperature neutrality, albeit at a hefty price.

While it’s true that foam mattresses tend to sleep hotter than other mattress types, some manufacturers have begun incorporating cooling components into their mattresses. Gel, graphite, copper, and other heat-wicking materials are commonly infused into comfort layers to keep the sleeping environment at a pleasant temperature.

In many cases, a trial run of getting enough sleep can make all the difference. Don’t buy a mattress before giving it the full test of time during the trial period. Overheating is a sign that the model isn’t right for you.

My bed is too hot; what should I do? There are some things you can do to ensure a more restful night’s sleep if, like many people, you tend to get too hot while in bed. Starting with the right bedding and pillows is a great place to begin improving your sleep. Sheets made of natural fibers like cotton percale, linen, or rayon from bamboo can help regulate body temperature and counteract the warming effects of a hot mattress. A mattress topper that actively or passively regulates temperature may also be useful.

Your comfort in bed can be maximized by modifying the temperature in your room. The ideal temperature for a good night’s sleep, according to most physicians, is between 60 and 67 degrees. When the weather outside is hot, you can cool off in your bedroom with a fan, air conditioner, or swamp cooler.

If none of these solutions work, you may want to look into upgrading to a mattress with better temperature regulation. Take advantage of in-home sleep trials to make sure your replacement mattress has adequate cooling. The vast majority of online mattress manufacturers provide at least a 90-night trial period, with some going as long as a year. If the trial period is longer, you can put the bed through its paces in a variety of climates.
