A trundle bed is a compact bed frame and mattress that sits low enough to the ground to be stored underneath another bed. The frame has wheels, making it easy to roll out and use. This space-saving design is ideal for people who want to be able to comfortably accommodate guests but have limited room available.

A trundle bed is a little bed that may be put under a regular bed because of its low profile. There are wheels on the base, so you can easily move it anywhere you need it. This clever layout is perfect for those who wish to host visitors in luxury but have a restricted amount of area to work with.

What Is a Trundle Bed?

The frame and mattress of a trundle bed are designed to be compact enough to be stowed away under a larger bed. With the wheels on the base, setting up and using the frame is a breeze. If you want to host visitors in luxury but have a small living area, this layout is perfect for you.

Trundles Defined

A trundle is a large, rollable platform that may be stored under a regular bed. It’s interesting that the word appears to have originated from an archaic word for the noise made when something rolls over the floor, because that’s exactly what a trundle does. Modern casters make it simple to roll the platform out across hard floors or carpet, and the platform is styled to complement the bed and make the most of the space under it.

A trundle is often a Twin-sized frame that is low to the ground and on wheels, but Full-sized trundles are also not uncommon. In order to ensure easy storage and pull-out mechanisms, the lower mattress is usually thinner than that of a standard mattress. A typical trundle mattress is 8″ thick.

What Is the Purpose of a Trundle Bed?

Low to the ground and on wheels, a trundle is typically designed for a Twin mattress, though Full trundles do exist. As a general rule, the bottom mattress is designed to be thinner than a regular mattress so that it may be easily stored and pulled out as needed. Typically, trundle beds have mattresses that are 8 inches in height.

Is a Trundle Bed a Good Idea for You?

There are a few things to consider when deciding if a trundle bed is a good choice for you:

  • Do you frequently have visitors stay the night, or do your children frequently host sleepovers?
  • How often do you have guests staying the night if you do?

A trundle bed could be an excellent option if you responded yes to the first question. In contrast, if you responded “frequent” to the second question, it’s probably a good idea to buy a real bed and mattress for guests instead of a trundle.

How Does a Trundle Bed Work?

A trundle bed has a lower bed that pulls out from under the upper bed, creating the effect of two separate beds. The upper bed will be a conventional bed with a conventional bed frame, while the bottom bed will be a slim mattress platform with wheels. You can easily access the trundle by rolling it out from under the main bed.

Are Trundle Beds Comfortable for Adults?

Trundle beds, with their space-saving designs, are a typical fixture in studio apartments, guest rooms, and kids’ bedrooms.

In most cases, the trundle is allocated for kids, teens, and young adults because of its smaller size, thinner mattress, and low profile (compared to older visitors). Trundle beds are also frequently found in the guest rooms of homes that frequently host out-of-town relatives for extended stays, as well as in the bedrooms of children and teenagers who frequently host friends for sleepovers.

Are All Trundle Beds the Same?

There are a variety of trundle bed styles available. There are also “bed in a bed” models that feature a separate sleeping area below the main mattress. The bigger frame in these combinations is accompanied by a separate trundle frame and mattress meant to fit underneath.

Additionally, trundle bed frames can be purchased independently from the beds they are meant to complement, either with or without a mattress. Customers who plan to buy a separate frame and/or mattress should measure their bedroom well to ensure everything will fit.

A trundle bed’s dimensions and height are both customizable. When rolled out from below the main bed, some trundle frames are designed to remain low to the floor, while others are able to pop up to a more conventional bed height.

It’s also important to note that the quality of construction might vary greatly from one trundle bed to the next. A trundle frame’s load capacity, aesthetic appeal, and endurance can all be affected by whether or not it’s constructed from high-quality materials.

What Are the Types of Trundle Beds?

A wide variety of sizes, designs, and built-in storage solutions are available for trundle beds.

A conventional Twin bed and a Twin trundle, for instance, can be all that’s needed in a child’s bedroom. Queen over Twin trundle beds may be more appropriate for a guest room that needs to accommodate both adults and children.

Because of the additional drawers attached to the trundle frame, a captain’s bed with a trundle can be an excellent solution for small living quarters like studio apartments that are short on both floor space and closet space. You can also utilize a regular trundle or a popup trundle with different bed frames, such as a daybed or a bunk bed, with the Twin over Twin or Twin over Full sizes.

Additionally, building materials will range. Trundle beds come in a variety of styles, from the more conventional upholstered kind to more rustic wood options. You may go with a wrought-iron frame for added strength and a more industrial look.

What Size Is a Trundle Bed?

The standard sizes for trundle beds are the Twin, Full, and Queen. Beds with trundle beds connected are often either the same size as the trundle itself or one size larger. (That’s why it’s common for a trundle bed to be an additional Full or Twin in size when used with a Full mattress.)

What Size Mattress Is Best for a Trundle Bed?

The trundle section of most trundle beds is made to fit a standard Twin mattress. Trundle beds are available in multiple sizes, from Twin to Queen, and require a correspondingly sized mattress. The most crucial aspect of a trundle bed mattress is its height, as a mattress that is too tall will prevent the trundle from closing. (A standard trundle mattress is between six and eight inches high.)

What Are the Benefits of a Trundle Bed?

One of the best things about a trundle bed is how little space it takes up when it’s not in use. Since it can be placed under another bed, it won’t take up any floor space and may still be used for storage.

Most trundle beds come with a mattress that is significantly more comfortable than alternatives such as air mattresses or camping pads, but taking up significantly less room. A trundle mattress is preferable to a sofa for overnight guests.

What Are the Downsides of a Trundle Bed?

Even though trundle beds are convenient and look nice, they do have some drawbacks when used as extra beds. Trundle bed frames and mattresses are typically thinner and lower quality than standard beds since they need to fit beneath another bed. Since this is the case, heavier individuals won’t be able to use the frame properly. A trundle bed isn’t meant to be used on a regular basis because the thinner mattress may not provide enough comfort or spinal support.

While a trundle takes up little room when not in use, it can become quite bulky when it is. Customers should compare the trundle bed’s dimensions to those of the room to ensure that the bed won’t make the area uncomfortable.

What Are the Types of Trundle Beds?

Buying just the trundle frame is an option, but you can also locate full trundle beds for sale. Some examples of the sets’ designs are:

  • The space-saving potential of a trundle bunk bed is increased because the third bed is created by sliding the trundle under the bottom bunk.
  • Daybeds with trundles are a cross between a couch and a bed, with the extra sleeping space provided by the trundle underneath the bed.
  • The trundle bed can be tucked away neatly and easily when not in use thanks to this set’s ingenious drawer design.

How Much do Trundle Beds Cost?

The price of a trundle bed can vary widely depending on its quality and whether or not a mattress is included in the purchase. A simple frame for a trundle bed can be purchased for as little as $75, while more elaborate trundle bed sets can cost as much as $500.

Where is the Best Place to Buy a Trundle Bed?

You may get trundle beds for sale either in-store or online. Most places selling mattresses and furniture also stock them. There are a plethora of online retailers that stock them, including popular names like Amazon.

Customers making purchases both online and in stores need to pay special attention to whether or not they are purchasing merely the frame or the whole trundle bed set. Not only is it important to measure yourself for a mattress, but you should also measure the measurements of the bed you plan to use.

The shipping fee should also be considered by online shoppers. The purchase price of a trundle bed may or may not include professional assembly. If it’s the latter, then how simple it is to set up could be important.

What Are Alternatives to a Trundle Bed?

Options other than a trundle bed are available to customers who want to accommodate overnight guests.

  • Temporary air mattresses are more compact and affordable than traditional mattresses, but they often lack the same level of comfort and durability.
  • You can save floor space by using a sleeper sofa or pull-out couch instead of a trundle bed, and some of these pieces come in sizes that are larger than a twin. A sofa bed is a couch that can be converted into a bed by folding out the frame and mattress. Because of the thinness of the mattress, sleeping on a pull-out couch isn’t always the most comfortable option.
  • Like a sofa-bed, a futon can be used as either a couch or a bed. There is no change in the mattress used between the two variations. The frame can be angled or laid flat, and this is the only difference.
  • A bed frame and mattress can be stored vertically inside a murphy bed’s accompanying cupboard. It can be as convenient as a trundle bed while complementing a variety of decor styles.


Are trundle beds comfortable?

Your trundle bed’s level of comfort and support will change depending on the mattress you choose. Most trundle beds have mattresses that are only 8 to 10 inches thick, making them uncomfortable for anyone with back discomfort.

Can you add a trundle to any bed?

In case you were wondering, trundles and bed frames are available for purchase alone. However, the trundle will not work unless your bed frame is high enough off the ground to accommodate it.

Although some trundle frames are only 6 inches in height, others are more than 10 inches, so you’ll want to account for both when shopping. Your bed frame should have around 16 inches of space between it and the floor.

Do trundle beds work on carpet?

There is no problem putting a trundle bed on the carpet. Even if your trundle wheels don’t lock, using the bed on carpet can help keep it in place. While some trundle beds may have convenient handles that make it easy to move them, pulling them out on carpet may be trickier than on hard surfaces like wood or tile.

Can you sleep on a trundle bed all the time?

Yes! Trundle beds are used exclusively by many children who share a bedroom with their siblings. Use a high-quality mattress and pillow to guarantee a restful night’s sleep. Thin mattresses are required for trundle beds, but they should not compromise on support or quality of sleep.

What other beds are suited for small spaces?

Alternatives to the trundle bed that can fit into a compact room are:

  • A Murphy bed, or wall bed, is a type of bed that can be stored upright against a wall and then lowered down to use as a bed when needed.
  • Loft bed: This design is like a bunk bed but only has one sleeping level. The area under a lower bunk is often used for a couch or a workstation instead.
  • Futons are convertible sofas and beds in one. The structure can be used as a couch during the day and folded out into a bed for the night.
  • In contrast to a futon, a sofa bed is a conventional sofa that converts into a bed. Sofa beds are designed with daytime seating cushions that can be removed and replaced with a mattress for overnight sleeping comfort.
  • A rollaway bed is a lightweight and collapsible alternative to a traditional hotel bed. Rollaway beds include metal frames with wheels and a collapsible design for storage.
  • Air mattresses: Inflatable beds that are ideal for camping or extra visitors.


For extra seating or sleeping space, trundle beds are a great option for visitors or kids. And a trundle bed can save you the expense of setting up a separate guest room. Many trundle beds also provide extra space for clothing, books, toys, and other items. In general, they are a space- and cost-efficient choice.
