Bunk Bed Mattress Buying Guide

Perhaps the most obvious consideration when selecting a mattress for a bunk bed is whether it fits into the bunk bed’s design. However, there are other factors to take into account including the type of bunk bed you’re purchasing it for, budget, safety features, and more. In this buyer’s guide, we share everything you need to know prior to purchasing mattresses for your bunk bed.


These are the most common types of bunk bed designs sold today. Determining the type of bunk bed you’re outfitting is an essential step in choosing the right mattress.

Standard—This is a ‘classic’ bunk bed style that features two twin-sized mattresses stacked on top of each other: one at the bottom and one at the top. Most feature a latter that ascends to the top bunk and some feature a guard rail and the option to disassemble the bunk into two separate twin beds.

Standard Loft—Think of lofts as a classic bunk bed without the bottom bunk. A loft bunk bed has the top bed but leaves the bottom space open for storage, a desk, or a relaxation nook.

See: Best Loft Beds 

Triple—A triple is simply a tall variation of the standard bunk bed and features three beds (twin-size) stacked on top of one another. Some triples place two mattresses next to one another on the bottom with the third on top.

Triple Loft—A triple loft bunk bed features two bunk beds in an L-shape on the top layer and one twin-size bunk bed on the bottom. The open side of the ‘L’ on the bottom is left open for storage, a desk, or a nook.

Trundle—A trundle bunk bed features a traditional bunk bed design with the addition of a third bed housed in a pull-out drawer beneath the bottom bunk. They’re an innovative, space-saving design for children who enjoy having sleepovers with friends or for people with limited space in a room where the bunk is kept.

Twin-over-Full—Twin-over-full bunk beds are designed with a smaller bed on top of a larger bed. They can provide sleeping space for up to three people, with two people sleeping in the full-size mattress and one in the twin-size mattress up top. 

L-Shaped—An L-shaped bunk bed has two beds that are placed perpendicularly. Most L-shaped bunk beds feature two twin mattresses, but some may feature a full-size on the bottom bunk.


Healthy sleep is essential for growing children and adults, regardless of who will be sleeping in your bunk bed set. The right bunk bed mattress will provide a comfortable yet supportive surface and may be able to accommodate children as they grow. Here’s what to consider when you’re shopping for a bunk bed mattress that will suit the bed’s frame, you or your child’s sleep needs, and you or your child’s personal preferences.

Mattress Size—The vast majority of bunk beds and similar style beds sold today are designed to fit Twin-, Twin XL-, or Full-size mattresses. We recommend measuring the bunk bed’s mattress space prior to making your purchase decision. For reference, the typical measurements for the mattresses we’ve mentioned are as follows:

  • Twin-size dimensions: 38” x 75”
  • Twin XL-size dimensions: 38” x 80”
  • Full-size dimensions: 54” x 75”

Profile—Most top levels of bunk beds feature guard rails that prevent children and sleepers from hurting themselves by rolling off of the bed in the middle of the night. A guard rail coupled with a low-profile bed is often the best solution to ensure safety. As such, we recommend a mattress that measures 9” thick or less.

Cover Material and Design—In general, the cheaper the bunk bed mattress, the more simplistic its cover design. This is an especially important factor to consider for bunk bed mattresses because children, who may be more prone to accidents and spills, typically sleep on them. Look for covers with zippable, removable designs that are also washing-machine friendly. Quilted covers can also help improve the comfort of the mattress as a whole.

Firmness—For children, we recommend firmness settings of medium-firm or softer. The older and heavyweight the child, the more firm the bed should be. 

Mattress Type—There’s no right or wrong when it comes to the best mattress type for bunk beds. Whether your child prefers innerspring, memory foam, hybrid, or latex, there’s likely a bunk bed mattress out there to suit their needs. Keep in mind there’s a unique set of pros and cons for each mattress type.

Motion and Noise Isolation—Mattresses that isolate motion and dull noise can be especially beneficial for bunk beds, which typically sleep two or three people. Mattresses with low responsiveness, excellent motion isolation, and low noise potential will help your children (and their friends) sleep soundly and reduce disruptions from sleepers on the other bunks.

Cost—Most mattresses for bunk beds have reasonable price points because they’re small in size and therefore useless material. Bunk bed mattresses also tend to be less durable than others on the market due to the fact that most sleepers outgrow their bunk beds within less than five years. If you have the budget to spend extra money to ensure your bunk bed mattress contains luxury materials or will last a long time, feel free to invest, but a value bunk bed mattress can work just as well for your child.

Picking the Right Bunk Bed Mattress

Now that you have a better understanding of the average bunk bed mattress price point, the various types of bunk bed mattresses, and the most important shopping considerations when buying a bunk bed mattress, it’s time to make a decision. Here’s a quick step by step to choosing the best bunk bed mattress for your home:

  1. Evaluate your bunk bed’s style (standard, L-shape, etc.)
  2. Measure the sleeping spaces to determine mattress size(s) (Twin, Twin-XL, Full, Custom, etc.)
  3. Determine your bunk bed mattress budget, making sure to double or triple if your bed requires more than one mattress
  4. Make a list of the most important factors in your bunk bed mattress purchase (firmness, profile, comfort, type, etc.)
  5. Review the list of our top five bunk bed mattresses of 2021 to see if there’s a bunk bed that can suit your needs
