It’s possible that your mattress isn’t getting the proper support. The quality of a mattress is directly related to the quality of its base. A box spring or a group of slats are commonly used to support a mattress.

Despite the fact that they both serve the similar purpose—to support your mattress from the bottom—they both have their own advantages and disadvantages. What’s the difference between a box spring and slats?

Here, we’ll go over the distinctions between these devices, as well as who they’re most suited for and why, so you can make an informed decision about which base is ideal for your situation.

The Higher The Better?

In addition to personal taste, the height of a bed can have an impact on the quality of one’s sleep. It may be difficult to get a good night’s sleep if your bed is too high or too low. Some people prefer to sleep on their backs rather than their stomachs because they feel more at peace in a higher position.

Then again, there are other things to consider. A bed that’s too low or too high may make it difficult to get out of if you’re elderly. There’s a risk of straining your back when changing sheets in a lower bed because you’ll have to lean down deeper.

What are Bed Slats?

Structural support for a mattress on a platform bed is provided by bed slats, horizontal boards of wood or metal. Typically, they are spaced around 2-3 inches apart to distribute the mattress’s weight equally. The number of planks in your bed may vary depending on the size of your mattress.

Both normal and spring boards can be used. Planks that have been sprung have a curved shape that allows them to bend and move more easily. It is better to use standard planks for individuals who prefer firmness, while springs are best for those who prefer more supple support.

What Are Slats Most Suited For?

Back, stomach, and side sleepers are all likely to benefit from slats if they are paired with the correct mattress. This type of mattress is ideal for stomach sleepers, who want a firmer surface to rest their heads on. Hot sleepers will like the increased airflow these boards provide because they help keep them cool at night.

Pros and Cons of Slats

The advantages and disadvantages of employing slats as a bed’s base will now be discussed.


Slats Benefits

Slats are more economical than other mattress foundations since they use less material, making them a good choice for consumers on a budget.

Among other things, these planks are notable for their long-term resilience and light weight. If you move regularly or plan on doing so in the near future, these should be easy to construct and transport because of their lightweight design.

Slats Downsides

Planks may sag if they are set more than three inches apart, which is one of the drawbacks. The sort of mattress you sleep on is also important to consider. Memory foam, for example, may be more prone to sinking through the gaps between planks because of its body-contouring properties.

If the boards aren’t secured properly, they could fall or move throughout the night, which could cause an accident.

What are Box Springs?

You can also use a box spring, which is a covered base that sits right under your mattress. Wood and metal are common materials for these products.

For bounce and longevity, traditional versions of this device use coil springs; however, most modern ones are hollow within and do not have springs. In order to provide support, the springs push against the coils of an innerspring mattress. Wheels can also be added to modern springs to make them easier to move.

What Are Box Springs Most Suited For?

Whether you go with a liquid or a powder foundation is a personal preference. Back, side, and stomach sleepers should be able to enjoy this product with the correct mattress.

Those with back difficulties may like this foundation because it’s simpler to get out of and you don’t have to bend over as far to change the sheets.

Pros and Cons of Box Springs

You can now weigh the pros and disadvantages of this product to see if it’s right for you.

Box Spring Benefits

Stable mattress support comes from the box spring construction, which is less likely to sag. As an added bonus, it provides a lot of height in comparison to a slatted base. For those who prefer extra height, this is a big gain.

It’s also a bonus if you have an innerspring mattress and a classic framework that includes coil springs.

Box Spring Downsides

On the other hand, many objects are heavy and cumbersome to carry, which may be especially aggravating when it’s time to downsize or relocate. They are also more expensive than planks and don’t allow for as much air flow.

Also keep in mind that some of these products may not have much storage space under your bed, and the cloth on them may be tough to clean.

Frequently Asked Questions

How much weight can bed slats hold?

When selecting what kind of foundation you require, weight is also a factor to keep in mind. To ensure that the foundation can sustain your weight and the weight of your mattress, you must take into account both of these factors.

The majority of modern slatted beds can sustain up to 600 pounds, however some are only designed to support up to 350 pounds. Check the weight capacity of a slatted item before buying it to avoid problems with your bed in the future.

Can you use a boxspring with slats?

Box springs and slats are the only two options for your bed’s base. A level surface between the mattress and the slats may still be preferred by certain sleepers, especially to prevent sinking. Instead of a box spring, use a bunkie board or a piece of plywood.

An average bunkie board is a thin to medium-thick piece of plywood, usually between one and three inches thick. Wood, plywood, and other materials can be used to create this product. Bunkie boards were originally designed to serve as a foundation for bunk beds.


How long are slats for a twin bed?

The width of a twin mattress is 38 inches. A twin-sized bed frame should have slats that are between 40 and 44 inches long. Having an extra 2 to 3 inches on either side means the mattress won’t be crammed in too tightly against the frame.

Can I use plywood instead of a box spring?

Slats may need to be spaced no more than 2.75 inches apart depending on the sort of mattress you have. If slats are too widely apart, for example, memory foam beds may be harmed. A 1-inch piece of moisture-resistant plywood can be placed on top of the slats of your bed frame to support your mattress and prevent it from sinking.

Similarly, a bunkie board accomplishes the same thing. One to three inches thick and built of wood, plywood or particleboard is typical. It doesn’t matter what style of bed frame or foundation your mattress lies on, a bunky board provides a stable and supportive basis.

How much weight can bed slats hold?

Most modern bed frames with slatted foundations can sustain up to 600 lbs. of weight. However, some are only meant to support up to 300 pounds, so check the manufacturer’s weight limit before you buy.

They can cause major health problems if they are exposed for a long time.

How many bed slats do I need for a full size bed?

Double beds, or full-size mattresses, are 54 inches broad. The majority of full-size bed frames have slats that are 56 to 60 inches in length. slats In most cases, the length of the slats is between 2 and 6 inches longer than the mattress.

How much weight can bed slats hold?

In most modern bed frames with slatted foundations, 600 pounds is supported. Some slatted foundations, on the other hand, can barely support 300 pounds. Be sure to check the weight limit with the manufacturer before making a purchase. The weight of a mattress is also a significant consideration.

Should I use metal or wood slats?

However, wooden slats are less expensive than metal ones, but they may not be able to hold your mattress as well. With the weight of a mattress and a person resting on it, metal slats are a better option than wood slats. Metal slats, on the other hand, are less likely to flex or shatter than wooden ones.

Can I use a box spring with a latex or memory foam mattress?

As a general rule, it is not advisable to use a box spring with a latex or memory foam mattress. Latex and memory foam mattresses are not supported by box springs. In addition, the mattress’ weight may cause the springs to bend. Slatted or sturdy foundations, as well as platform beds, are superior choices for foam beds.

Can you buy slats for a bed frame?

You can buy slats for your bed frame individually. Sleepers on a tight budget can use bed slats as a cheap foundation for their mattress. Bed slats can be installed fast and easily on top of a bed’s frame instead of a box spring.

Do bed slats break easily?

When you put on a lot of weight, some slatted foundations can break easily. It is possible to bend the slats of your mattress if you put too much weight on one slat or part of the bed. If you’re going to buy a mattress foundation, make sure it can support the weight of your goods.



The components of the mattress are important if you’re not sure which one to buy. The benefits and cons of each product are unique. As an example, slatted bedding may be more enticing to you at a lower price point, but its height may not be.

It’s also important to take into account the type of mattress you have. It’s possible to sink into the bed without the use of a bunkie board for memory foam mattresses, which are designed to conform to your body.

You should be able to pick the right base for your sleep and lifestyle demands after examining the capabilities of these items.
