5 Best “Bunk Bed Mattresses” to Buy Online | (Proper Thickness & Fit)
In general the bunk manufacturers suggest a thinner mattress that sits far enough below the guardrail so that you do not fall off the bed.
Generally the mattress for a bunk bed should measure about 8″ thick or thinner. It is important to measure or look at the requirements for your specific set up to be sure what works for your specific bunk bed set.
In this post we have listed our favorite mattresses that are all between 6 inches and 8 inches thick, which is our recommended thickness for the vast majority of bunk beds on the market today. A mattress of this thickness sits low enough to be safe and to allow the guardrail on the bed to do its job, while also still providing enough support.
IMPORTANT NOTE: All of the mattresses on this list below are 8″ thick or thinner and will safely fit the vast majority of bunk beds on the market. For safety reasons, a bunk bed mattress should not generally be thicker than 8″ (always check with your specific bunk bed manufacturer for mattress requirements related to your bunk bed model).
A mattress that is too thick will lift the sleeper too high above the safety rail and could increase the risk of falling or injury.

How thick should a bunk bed mattress be?
The majority of bunks fit a twin/ single or full/double sized mattress between 6″ and 8″ thick. If you are unsure, we recommend a 6″ mattress, as this will ensure the mattress sits low enough that you won’t be able to roll out of bed past the guardrail. 6 inch thick mattresses are not as common in the market as other sizes so your options will be slightly limited.
What is the best type of mattress for a bunk bed?
Since a bunk bed requires a thinner profile mattress, you want to make sure you try to purchase one that is of nicer quality and that won’t begin to break down or sag. Many of the cheap mattresses on Amazon are imported from China with poor quality foam and will not last or hold sleepers of any substantial weight. A higher quality mattress will have a high density base foam that can support any type of sleeper and will hold up for years to come. You can choose from a variety of materials from latex to memory foam depending on your personal comfort and material preferences.
Things to consider before buying a mattress for your bunk bed.
Frequency of Usage: We have listed mattresses that meet all standards and budgets. Be sure to think about how often you will be using your mattress. If it will be a guest bed or an extra sleeper you may want to go with a budget mattress, while if it is an every night sleeper you may lean towards a more luxury sleeping experience.
Material: When it comes to material memory foam, latex and innerspring mattresses all have different benefits and feels. It is important to know which you prefer and choose a mattress that meets your needs.
Price: Generally speaking, the more expensive the mattress the higher quality materials and the longer it will last. Our best all around mattress is a great middle ground between quality materials and an affordable price.
The different types of bunk mattresses available
Thinner mattresses that are used for bunk beds are not as common in the marketplace, but you still have a variety of styles and options to choose from. Each material and mattress style comes with its own benefits and downsides.
Memory Foam: Memory foam was originally invented and used by NASA and ultimately transitioned into use within the sleep industry. Memory foam has great pressure relief abilities but can have a unique feel that takes some getting used to. If you have never slept on a memory foam mattress we recommend testing one out before deciding to purchase one.
Latex: Latex is one of the most natural and eco-friendly materials in the bedding industry. Latex is not only a popular health-conscious choice but it also has amazing pressure relief and support capabilities. The only downside to latex is that it is quite a bit more expensive than competing foams.
Innerspring: An innerspring mattress is going to give the most support and “bounce” out of all the mattress types. Innerspring mattresses are also commonly referred to as “hybrid” mattresses. If you have back pain or are looking for additional support, then we generally recommend an innerspring option. Innerspring mattresses will also usually hold up longer than the all foam competitors.
