Our editors have spent hundreds of hours testing, reviewing, and researching beds of all sizes and from all brands. We have experience with air beds, coil beds, foam beds, and everything in between—even the unique gel-like bed that is the Purple mattress.

Several of our team members are “Certified Sleep Science Coaches” as well, so rest assured all we do everyday all day is think about and recommend beds. As it relates to bunk beds specifically, we have a lot of first-hand knowledge on the subject. Virtually all of the mattresses we’ve tested come in both the twin and full size, and should serve as good candidates for your bunk bed. But enough with the wind up, let’s take a quick glance at our list of the best bunk bed mattress:

The Best Mattress For A Bunk Bed In 2020

Now that you’ve seen the list, you might be thinking about how we selected the beds that we did. Well, we base a lot of our selections on what people are searching for. As an example, we know the memory foam mattress is the most popular type of bed online, so it only made sense to include one of these beds. Additionally, our editors get together to discuss and argue the merits of every single mattress. It takes us several hours to curate our lists and come to a final conclusion.

We understand that you probably want to know more about each of our selections. That’s why we’ve included reviews sections below. They are shorter than our typical in-depth reviews, but they should provide ample context for you to make a decision. Hopefully you find this guide helpful!

What Size Is A Bunk Bed Mattress

Now that you’ve read more about our top picks, let’s cover some basics about the bunk bed mattress. Perhaps the biggest question we get about is about the size of the mattress, so let’s start there. Put simply, the size of bunk bed mattress you require is either the twin or full. Allow us to explain.

The most popular size of mattress for a bunk bed is the twin mattress, which typically measures 75″ long by 38″ wide. Most bunk beds will have the twin mattress on the bottom and on the top (i.e. twin over twin bunk bed). The twin size mattress will only fit on person comfortably, and usually it’s not best for adults. If you have an adult bunk bed, it will most likely have a full size mattress.

There are full over full bunk beds which are fairly popular as well. These will obviously require a full mattress on top and bottom, and the average full mattress is 75″ long by 54″ wide. Typically, you will buy a full over full bunk bed for larger kids, teens, and adults.

Another common type of bunk bed is the twin over full, which is exactly what it sounds like. This requires a twin mattress on top and a full mattress on bottom. These are ideal of siblings of different ages to share the same room. From what we’ve seen, these are the most interesting and elegant types of bunk beds because the manufacturers have more leeway to get creative with the design.

Tuft And Needle – Best Bunk Bed Mattress

Why Buy The T&N Mattress — If you can only pick a bunk bed mattress, Tuft & Needle is a great place to start because it’s a simple, yet comfortable mattress and the price point is completely reasonable.

Tuft & Needle is the classic online mattress

Laying on Tuft & Needle is like laying on one big slab of comfortable, neutral foam. It has zero memory foam and no springs, so it just has the classic soft foam feel.

We have posted a full review of the Tuft and Needle Bed, but here are the quick points to consider:

  • Free shipping and returns, along with a trial period
  • Price point is under $400 for the twin mattress [Check Price Now]
  • Soft foam feel
  • About a “medium” in terms of firmness
  • Good for all sleep styles
  • Measures 10″ thick with two layers of foam in total
  • Backed by Serta-Simmons
  • Has the CertiPUR-US and GREENGUARD Gold Certifications
  • Removable cover, but it is recommended to only hand wash

There’s not much to rant and rave about with Tuft & Needle, and that’s why we love it so much as a bunk bed mattress. It’s a foam bed and not much more. Plus, the price is something you’ll be happy with.

Bear Mattress – Best Memory Foam Bunk Bed Mattress

Why You’ll Like Bear Mattress — This is a traditional mattress in a box, in that it’s about 10″ thick and is made of foams. If you’re looking for a memory foam feel and you want to pay a very reasonable price, we think you’ll be very happy with Bear Mattress.

Bear even has a special Celliant cover that helps with restful sleep

This is the company’s entry-level mattress, but it’s perfect for a bunk bed since it’s not too thick, yet it’s a really nice bed for the money. We also think it could work for adults and kids alike.

Obviously, there’s a lot to know with Bear Mattress, but here’s a quick overview of the bed:

  • Free shipping and returns + a risk-free trial period
  • Twin size mattress sells for (well) under $500 [Check Price Now]
  • 10″ thick with three layers of foam
  • Graphite-infused memory foam is the main comfort layer
  • Somewhere between a “medium” and “medium-firm”
  • Suitable for all sleeping styles
  • Made in the USA
  • Celliant cover is FDA-approved
  • CertiPUR-US certified

Interestingly, Bear was one of the first brands to start selling beds online. While this is an all-foam bed, they do make Bear Hybrid, which is a little more expensive but adds the coils for support. As it relates to the bunk bed, however, we prefer the original Bear Mattress.

Brooklyn Bedding Signature – Best Hybrid Bunk Bed Mattress

Why Brooklyn Signature Is A Great Idea — This is our top pick for the best innerspring bunk bed mattress because it has just about everything you could ever want: it’s comfortable, supportive, affordable, and comes in three firmness options.

Most coil beds online are either pricey or measure taller than about 10″ thick. Brooklyn Signature, however, is both incredibly affordable and should fit just fine on most bunk beds. Here’s a little more about this mattress:

  • Comes with free shipping/returns and has a 120-night trial period
  • Sells for under $500 after you apply a coupon code [Check Price Now]
  • Support provided by the 6″ pocket coils
  • Has a “soft foam” feel (i.e. no memory foam)
  • Available in a Soft, Medium, and Firm
  • Works for all sleeping styles
  • Made in United States at Brooklyn Bedding’s facility in AZ
  • Ships in a box

Flat out, this is one of our favorite hybrid mattresses. It’s just an odd mix (in a good way) of value, support, comfort, and quality—should serve as a great bunk bed mattress, whether in the twin or full size.

Puffy Mattress – Best Washable Cover Bunk Bed Mattress

Why Consider The Puffy Mattress — There are several reasons why we included Puffy on this list, but the most prominent one is the fact that it has a washable cover. Yes, it’s a comfortable foam bed, but what makes it stand out among the others online is that you can remove the cover and wash it in the washing machine—perfect for kiddos with a bunk bed.

Puffy has a very similar “feel” to Casper, Leesa, and Tuft & Needle. By that I mean, it feels like a general soft foam mattress. It does have gel memory foam as its primary comfort layer. Aside from that, here’s what you should know about Puffy:

  • Free shipping and returns with a lifetime warranty
  • Measures about 10″ thick (3 layers of foam)
  • Washable cover
  • Sells for under $500 for the twin bed [Check Price Now]
  • Made in USA
  • Soft foam feel with a little memory foam mixed in
  • Ships in a box
  • Around a “medium” on our firmness scale

If you’re outfitting a bunk bed for kids, we expect that the washable cover will come in handy. You can learn more about Puffy in our full review.

My Green Mattress – Best Natural And Organic Bunk Bed Mattress

There’s Plenty To Love With My Green Mattress — Whether kids or adults will be sleeping on the bunk bed, Natural Escape by My Green Mattress should be equally as comfortable and resilient. This is a latex hybrid mattress with organic latex foam and pocketed coils. If you want health-centric material, it’s hard to do better than My Green Mattress, especially for the price.

You can think of My Green Mattress as a more affordable version of the Avocado Mattress, which is by far the most popular eco-friendly mattress online. You’re getting plenty of the upsides in terms of quality and comfort, but with a more palatable price tag. There’s a lot more to know with My Green Mattress, so here’s a short list:

  • Free shipping, returns, 120-night trial period, and 20-year warranty
  • Twin sells for under $800 before discounts [Check Price Now]
  • Made with latex foam and pocket coils
  • Non-toxic materials

Other Considerations For A Bunk Bed Mattress

Regardless of the size of mattress you choose for your bunk bed, the end result should be the same: a mattress that fits snuggly within the frame of the bunk bed and isn’t too tall. For the most part, that means looking for a mattress that’s no more than 12″ thick. Luckily, there are twin size and full size mattresses all over the place that are less than 12″ thick—we’ve included several in this review.

Aside from the thickness of the mattress, you will likely be choosing either a foam or innerspring mattress, though we are agnostic as to which you pick. Foam mattresses tend to be attractive since they’re highly affordable, but the coil beds can often provide more support in the long run. If you’re buying a bunk bed mattress for an adult, perhaps think about the coil beds first, but if you’re buying for a kiddo, the foam beds should be just fine.

Where To Buy A Bunk Bed Mattress

Given that you’re looking specifically for a bunk bed mattress, you might expect that you need a very specific mattress. In reality, that’s only mildly true. For instance, most bunk beds are using the twin mattress or the full mattress, or both. As such, it’s more about matching size, height, and budget when you’re purchasing a bunk bed mattress.

For most shoppers, the question is whether to buy a bunk bed mattress online or in-store. Fortunately, for you, there are plenty of options. We prefer the online mattress shopping experience because most of the beds come with free shipping and returns. Therefore, whoever is going to sleep on the mattress has several weeks to make up their mind about the bed. If they choose to return, in many case, a 100% refund is in order. That cannot be said if you’re shopping in-store for a new mattress.

If you need a cheap twin bunk bed mattress, well then, you’re likely going to be shopping online since there are dozens of options from which to choose. You can get Bear, Nectar, or a handful of other beds if you like a memory foam feel. If you want a general soft foam feel, there are countless options, though, we happen to really like the products by Tuft & Needle.

The bottom line here is if you want the best mattress for a bunk bed, your options are numerous, in-store and online. It will all come down to personal preference and budget.
