As adults, we all have a fine appreciation of the importance of a deep, restful night of sleep to our overall well being. But can you imagine the impact of a good night’s sleep on the health of children?

This is one of the many factors which should drive you when shopping for the best mattress for bunk beds.

Keep in mind that uncovering the right one may require a lot of effort and skill unlike traditional mattresses for adults.

With the huge technological innovations in the mattress industry at the moment, making the right choice can seem Herculean.

This is why we’ve compiled comprehensive reviews of the best bunk bed mattresses below for your convenience.

How to Buy the Best Bunk Bed Mattress

Before you go out and order a bunk bed, it is important to be sure of what you want specifically. Once you have that under your belt, just pay attention to the most important attributes and ignore the rest.

Here are the most critical factors to watch out for.

Bunk Bed Mattress Size

What size is a bunk bed mattress? This is a popular question on the minds of many consumers during shopping.

Well, the most common mattress size for bunk beds in the Twin and Twin XL. In recent times, a few brands have also made available a new size known as the “Narrow Twin” which has been touted as specifically optimized for bunk beds.

Always consider the size of bed frame you own and buy accordingly. Also, don’t forget to take the sleeper’s body size into account during the shopping process.

For instance, if you’re buying a bunk bed for an adult or heavy teen, a Twin XL may be more advisable. This is because this bunk bed mattress tends to be slightly larger than standard Twins.

Type of Foam

Innerspring and foam mattresses are the 2 main types prevalent in the bunk bed market at the moment. However, each one comes with its positives and drawbacks.

Therefore, the type of foam material you end up choosing may largely depend on your personal preferences during shopping.

Innerspring Bunk Bed Mattresses

From Millennials to Baby Boomers, many of us grew up on innerspring mattresses and have gotten so used to them that sleeping on anything else feels awkward and uncomfortable especially in the beginning.

These mattresses feature a set number of steel coils which typically determine their degree of firmness.

One of the main reasons why they continue to be so popular is due to the extra bounce they provide. These types of mattresses are also genuinely sturdy and built to last through several years of routine use.

Additionally, most spring coil bunk bed mattresses are extremely breathable which can be lifesaving for those of us who live in hotter climates or prone to night sweats.

The downside is that dust mites and other allergy triggers thrive in these types of mattresses. If you or your children suffer from severe allergies, staying clear of innerspring models could be a wise decision.

Foam Mattresses

There is a wide range of options available when it comes to foam mattresses. Memory Foam, Latex Foam, and Polyurethane Foam are the most prominent types on the market.

Choosing a foam bunk bed mattress is not necessarily a bad idea. There are so many 5-star options available on the market and a glance through our reviews can help you uncover them.

However, traditional foam mattresses are known for their terrible heat dissipation which can be severe especially during summer.

Therefore, memory foam models integrated with layers of cooling gel make the best foam mattresses for bunk beds thanks to their quick and efficient heat disposal.

Foam mattresses are great for those of us with allergies as many of them are naturally hypoallergenic, ensuring that dust mites, bacteria, and other allergens are effectively eliminated.

Bunk Bed Mattress Thickness

Bunk bed mattress thickness should be another critical factor to consider especially among heavy teens and adults. This is because thicker mattresses tend to provide better weight support and increased comfort for sleepers.

The good news is that standard twin mattresses typically come with enough thickness to support those weighing 250 pounds or so.

When shopping for the best bunk mattress, make sure to choose a model that is no more than 6-7 inches thick.

Anything thicker and you risk the mattress stretching further than the guardrails which can make the sleeper susceptible to falls and resultant injuries.

The good news is that some bunk beds come with specially designed guardrails which are significantly higher than the standard ones on the market.

If your bunk bed features this style then you can afford to purchase a mattress which is up to 12 inches thick without any fear of putting the sleeper at risk of falling.

A low profile mattress is also recommended for bottom bunk beds. Remember, the thicker the mattress, the less headroom is available to the sleeper.

Also, thicker bunk bed mattresses can be difficult to lift and move around when tucking sheets underneath it.

Therefore, we recommend that you choose a model which is no more than 8 inches thick but provides massive comfort instead of buying one that is too thick to the point of discomfort as this could end up leaving you with nightmares down the line.


There’s no ideal firmness level that suits the needs of everyone. Firmness is strictly a matter of personal preference.

What might be too firm for one person may be deemed soft by another so you should always choose based on the individual needs of the sleeper.

What if you’re shopping for a bunk bed for kids? Well, we recommend that you speak to them to find out what they want. Their input could put the firmness problem to bed once and for all.

Just ask the child whether he or she prefers a soft or medium firmness mattress and you’ve got work cut out for you.

Customer Reviews

Customer reviews are a great way to get a feel of what a particular model brings to bunk beds even before purchase.

The good news is that retail giants like Amazon allow customers to leave independent reviews and rate their experiences for every single item purchased including mattresses.

Once you find a potential bunk bed mattress you like, a glance through its reviews can help you decide whether it’s a good fit for your needs or not.

Frequently Asked Questions

There can be tons of questions on your mind when searching for the right bunk bed mattress. Here are our answers to a few common ones.

Is Sleeping on the Top Bunk Safe?

The moment kids start asking for bunk beds, many parents begin wondering whether these beds are safe enough because of the risk of falls and injuries.

Well, the answer is Yes. Kids should be able to sleep comfortably and safely on the top bunk without any problems (in most cases).

However, making sure that a particular bed is built with durable materials to ensure sturdiness and safety is always crucial.

Once you tick the box for Build Quality, Guardrail Height should come up next. Always choose a model with a much higher guardrail as this can allow you to invest in a thicker bunk bed mattress model without putting your precious son or daughter’s health at risk.

Remember, there are additional risks associated with putting kids on bunk beds such as strangulation and it is important to observe the highest safety practices to ensure minimum risk of falls, trips, and other minor injuries.

What is the difference between Bunk and Loft Beds?

Many children reach a phase where they fall in love with bunk beds and if your child has gotten to that point then it is only normal that he or she starts nagging and lobbying until you give in and splash out on one of these space-saving beds.

To be honest, bunk beds come with so many advantages due to their compact sizes.

However, if you have only one kid and have no plans of adding to your family anytime soon, a bunk bed may be a waste because only one of the beds will be utilized most of the time.

Well… this is where Loft beds come in.

Loft beds are bunk-style beds featuring a single bed at the top with the down part designed for use as a storage area, desk, and chair, or extra space for playing.

When looking for the best loft beds, always take into account the safety features outlined for bunk beds to guarantee the safety of your child.

Should Bunk Beds Feature Stairs?

The answer is Yes… in my opinion. Sure, stairs may use up more space than a simple ladder but they can be safer for younger kids who may be prone to slips and falls.

If your kids are much older, then they should have no problems climbing down and up the top bunk on a ladder which takes up less space.

Are Bunk Beds Safe for Toddlers?

The answer is… No.

Many kids start angling for bunk beds right from around age 5 but unless you have much older kids you can reserve the top bunk for, it will probably not be advisable to shop for a bunk bed at this point.

Experts believe kids should only be allowed to sleep on the top bunk after turning 7.


It is quite obvious that there are loads of great options when it comes to bunk bed mattresses.

That being said, we believe the Signature Sleep Memoir Memory Foam Mattress is the best mattress for bunk beds right now.

When you factor in its ability to evenly distribute weight and allow consistent molding to the sleeper’s body, it doesn’t take a genius to note that this model stands tall among its peers.

Additionally, it is manufactured to meet Federal Flammability Standard 16 and a host of other safety requirements.
