Bunk beds are awesome space savers — whether it be for your kids’ room, a college dorm room, or wherever it is you need to put 2 beds with limited space.

Personally, I slept on the top bunk while one of my bros in college took the bottom. Looking back, those were some of the best days I’ve had. But, knowing what I know now, they could’ve been better had I cared enough to find a good mattress. 

I would’ve had better sleep which consequently could have made me more energetic and motivated. That is, after all, what a good night’s rest is supposed to do regardless of age. 

However, choosing the right mattress for your bunk bed can come with a few challenges. Don’t worry — we’re here to guide you through them.

Here, we’ve listed what we think are the best mattresses for bunk beds, written short reviews for each product, and wrote a short guide on how you can choose what’s best for YOU. Before we get into any of those, here’s how we chose what mattresses to put on our list: 

How we chose


With bunk beds, the thickness of your mattress has to be a priority. Remember, you’ve got limited headspace for both the top and bottom bunks and you also have to consider the height of the handrails.

Thicker mattresses take inches away from these two things and, in turn, compromise the safety of you and/or your child. 

Because of this, we narrowed down our choices to mattresses that are only between 5 and 10 inches thick.

But, to be honest, we feel like mattresses that are 8-10 inches thick are pushing the boundaries but for those of you with bunk beds with high handrails, you could probably make it work. Just remember to measure those rails before making any decision. 

Firmness and support

These two features typically go hand in hand — the firmer your mattress, the more supportive it also gets. The way we see it, your mattress needs to be innately supportive because bunk beds generally don’t have the depth to use box springs. 

Thankfully, many of today’s mattresses are designed to be supportive without the aid of box springs. Nevertheless, we think it’s an integral part of deciding whether a mattress has a place in our list and in your home. 

That being said, we generally recommend firm mattresses for young children to reduce the risk of suffocation. It’s highly unlikely, we know, but we never take safety for granted. For adults, teens, and older children, we’ll leave the firmness of your mattress to your preference. 


There’s memory foam, poly foam, latex, innerspring, hybrids, and a few proprietary materials from the mattress manufacturers themselves. These are just some of the most common materials you’ll see as you scroll through the internet shopping for mattresses.

None of them are perfect but all of them have their pros. Memory foam, for example, is largely regarded as the best type of material for pressure relief but it also traps heat. 

All these materials are great for bunk beds, so we considered each of their pros and cons, weighed them against each other, and decided whether or not they belonged in our list. 

Also, we highly recommend you avoid using an innerspring mattress for the top bunk, particularly if you’re buying it for your kid. Innersprings are the bounciest of the bunch (because, you know… springs) and we think it might encourage your child to jump around. One wrong hop could be disastrous and again, it’s always better to be safe .


If you’re here, we think there’s a good chance you’re raising a child or are a college student.

Both of those can be expensive, so you’re going to want a mattress that you won’t have to replace for years to come. And, even if neither of those situations relate to you, mattresses themselves are expensive, so you’re going to want them to last, too. 

Unfortunately, thinner mattresses such as those commonly used in bunk beds generally don’t last as long as their thicker counterparts.

However, that doesn’t mean we didn’t look for durable mattresses — we did, and we think some of them are here on this list. If there’s any mattress here with durability issues, we’ll be sure to mention it in their review. 

The weight of the mattress

This is particularly crucial if you or your child are sleeping on the top bunk. I mean, imagine having to change the sheets on a heavy mattress while you’re standing on the bed’s ladder. Not only would that be needlessly difficult but it could potentially be risky, too. 

We didn’t completely rule out heavy mattresses though, but we did take this into consideration. 


You’re going to want your mattress to at least be CertiPUR-US® certified but if a mattress has other 3rd party certifications that might signify that it’s safer, that’s more than welcome. After all, you or your child’s health should always be your utmost concern. 

Price-to-value ratio

At the end of the day, we all have budgets we need to stick to. To add to the challenge, some mattresses out there, we believe, are needlessly expensive. But, on a brighter note, there are also a few mattresses that are relatively affordable but pack more features than they’re supposed to.

So, before we add any mattress to our list, we asked ourselves:

“Is it worth it?”

If we thought it was, then it had a good chance to be featured. If not, then it automatically gets the boot. Oh, and we used the prices on twin-sized mattresses as our reference point because that’s the size used in standard bunk beds. 

Other features we considered:

  • Cooling features — Simply because it’s hard to get a good night’s sleep when you’re sweating from the heat or shivering from the cold. 
  • Other special features — These include zoned support designs, unique structures, free pillows, free sheets, free white glove delivery, and virtually anything else that might make your purchase more of a bargain. 
  • Off-gassing — Basically the odor of chemicals coming from most new foam mattresses. Frankly, it smells terrible but it’s also normal. The smell should linger anywhere from a couple of days to a couple of weeks but, obviously, the less time a mattress takes to off-gas, the better. 

The best mattresses for bunk beds

To us, the best mattress for bunk beds is one that balances comfort and safety. Therefore, they have to be thick enough to bear your body while still leaving room for handrails and headspace.

They also have to be innately supportive but not too firm that you don’t get any sort of pressure relief. Lastly, they have to be worth their price. 

As you might imagine, it can be hard to look for mattresses with those qualifications but here’s a list of what we think are the best of them:

  1. Sleep On Latex Pure Green Natural Latex Mattress
  2. LUCID 5-Inch Gel Memory Foam Mattress
  3. Zinus 6-Inch Spring Mattress (Set of 2)
  4. PlushBeds Natural Bliss
  5. Wayfair Sleep Two-Sided 8-Inch Memory Foam Mattress
  6. The Latex for Less Latex Mattress
  7. Linenspa 6-Inch Innerspring Mattress
  8. Signature Sleep Flex 6-Inch Charcoal Gel Memory Foam
  9. Zinus Green Tea Memory Foam Mattress
  10. Classic Brands Cool Gel 8-Inch Gel Memory Foam Mattress
  • BBB accredited business (A+ rating)
  • Uses 100& natural latex, organic  cotton, and organic wool
  • Durable, breathable, pressure relieving, and supportive
  • Multiple firmness options (soft, medium, firm)
  • Multiple thickness options (standard 8-inch and low profile 6-inch models)
  • 10-year warranty
  • 100-night trial period
  • GOTS, Oeko-Tex, Eco-Institut, Greenguard Gold certified
  • Expensive
  • Low profile model not sold on Amazon
  • Heavy

First of all, Sleep On Latex is a BBB accredited company with an A+ rating. If anything, that should tell you about their top-notch customer service. 

Moving on to the mattress, it uses 100% natural latex, organic cotton, and organic wool. With materials like this, we think it’s higher than average price is justified. Plus, latex is innately more durable and breathable than most types of foam, so there’s that, too. 

The mattress also comes with multiple firmness and thickness options. For thickness, it can either be standard (8 inches) or low profile (6 inches).

The difference between them is that the standard model has an extra 2 inches of latex foam which serves as the mattress’ comfort layer. Needless to say, the added material also makes the standard model heavier and more expensive. The low profile model is still fairly heavy though. 

Anyhow, we recommend the 6-inch version but if you want to go with the 8-inch mattress instead, make sure you have enough headspace and handrail left to still be safe.

Also, Amazon doesn’t seem to be selling the low profile model. So, if that’s what you’re interested in, we suggest ordering directly from the website. 

In terms of firmness, the Sleep On Latex Pure Green Natural Latex mattress can either be soft, medium, or firm. With the right firmness level, any sleeper could feel the pressure relieving and supportive prowess of this mattress. 

Other features of the Sleep On Latex Pure Green Natural Latex Mattress:

  • 10-year warranty
  • 100-night trial period
  • Free shipping and returns
  • GOTS, Oeko-Tex, Eco-Institut, Greenguard Gold certified
  • Affordable
  • Advertised directly for kids and bunk beds
  • 2 model options (2019 and 2020. We recommend the 2020 model)
  • Firm and pressure relieving
  • Sleeps cooler than regular memory foam
  • Great for both top and bottom bunks (not heavy and bouncy)
  • 10-year warranty
  • 30-night trial period
  • CertiPUR-US® certified
  • Off-gassing might be an issue (based on customer reviews)
  • Memory foam layer is just 1 inch thick
  • May require frequent rotations

The LUCID 5-Inch Gel Memory Foam Mattress is advertised as a mattress that’s designed specifically for kids and bunk beds — and that’s exactly how we see it, too! 

Before we get into detail, however, Amazon sells 2 versions of this mattress: the 2019 model and the 2020 model. We recommend getting the 2020 version for 2 reasons:

  • First, it looks better. Well, to us at least. The combination of black and white fabric makes the mattress look more chic. 
  • Second, the base layer is infused with bamboo charcoal which helps reduce odor and moisture. In turn, this could reduce the risk of having molds which, of course, is better for your child. 

The fact that the 2020 model has these additional features but still cost virtually the same is why we think it’s the obvious choice. 

Nevertheless, both models feel the same — they’re firm but pressure relieving and sleep cooler than regular memory foam mattresses (thanks to their breathable covers and gel infused in the memory foam). They’re not bouncy and heavy as well, so they’ll do great for both top and bottom bunks. 

If we had to complain, however, it’s that this mattress has some nasty off-gassing issues based on some of the customer reviews we’ve read.

Also, the memory foam layer is a little thinner than we’d like at just an inch thick, so you might want to rotate this mattress frequently to make sure it lasts longer. Otherwise, it’s a pretty durable mattress. 

Other features of the LUCID 5-Inch Gel Memory Foam Mattress:

  • 10-year warranty
  • 30-night trial period
  • Free shipping and returns
  • CertiPUR-US® certified
  • 2 mattresses for the price of 1 (practical option)
  • Great thickness for most bunk beds
  • Uses durable, supportive, and breathable Bonnell springs
  • 10-year warranty
  • CertiPUR-US® certified
  • Probably too firm for some people
  • Not a good option for the top bunk (too springy and heavy)
  • Thin foam layer may wear out easily
  • Trial period not specified

First of all, buying the Zinus 6-Inch Spring Mattress is one hell of a bargain because you’re actually getting 2 mattresses for the price of 1. It’s probably the most practical choice, at least as far as this list is concerned. 

It’s 6 inches — not a thick option but, to us, the perfect size for most bunk beds. The Zinus 6-Inch Spring Mattress also uses Bonnell springs which are traditional type springs used in old school mattresses.

They’re known for their even supportiveness and durability which we think works well for bunk beds. Innersprings are also known to sleep cooler than a lot of foam models, so overheating shouldn’t be a problem here. 

However, Bonnell springs are also extremely firm. So firm, in fact, that some people find it uncomfortable. The springiness of the mattress might not also be ideal for the top bunk, particularly when the person sleeping there is a child with tons of excess energy.

It’s also heavy (which we expected with Bonnell springs) which, in our minds, reinforces our point of this mattress probably not ideal for the top bunk. 

Moreover, this mattress only has an inch of foam on top of its coils. So, while the coils themselves can last a long time, the foam on top of them might not and this could lead to some issues with durability. Thankfully, this set comes with a 10-year warranty.

Other features of the Zinus 6-Inch Spring Mattress (Set of 2):

  • 10-year warranty
  • The trial period isn’t specified on Amazon but Zinus typically offers a 100-night trial period for their mattresses. We’re assuming it’s the same for this. You might want to contact Zinus to be sure though. 
  • CertiPUR-US® certified

  • BBB accredited business (A+ rating)
  • Uses 100% natural latex and organic cotton
  • Uses their own Eco Fire Barrier™ instead of wool (vegan-friendly)
  • Multiple thickness options (6, 8, and 10 inches)
  • Multiple firmness options (soft, medium, medium firm, extra firm)
  • Pressure relieving, supportive, breathable, and durable
  • 25-year warranty

  • Extensive list of certifications
  • Heavy
  • Expensive

From the company Plush Living, a BBB accredited business with an A+ rating, PlushBeds makes a bunch of top-notch bedroom products including toppers, beddings, bed frames, and of course, mattresses. To us, their Natural Bliss mattress is one of the best ones for bunk beds. 

Like other latex mattresses you’ll find on this list, the Natural Bliss uses 100% natural latex for its foam and organic cotton for its cover.

However, unlike the others, this mattress uses its own Eco Fire Barrier™ — a combination of plant fibers and silica — as its fire retardant instead of wool. This makes it animal free and, consequently, a great option for vegans. 

This mattress also comes in multiple thickness options: 6, 8, and 10. The difference between them is a 2-inch layer of Talalay latex — the 6-inch model has none, the 8-inch model has 1, and the 10-inch model has 2.

Of course, the thicker options are heavier and more expensive but they all come with a 6-inch layer of Dunlop latex and they’re all durable. 

The PlushBeds Natural Bliss also comes with multiple firmness options: soft, medium, medium firm, and extra firm. Except for the extra firm model where you have to pay extra, the firmness level doesn’t change the price. 

If you choose the right firmness level that fits your preferences, this mattress should feel pressure relieving, supportive, and breathable. 

Other features of the PlushBeds Natural Bliss:

  • 25-year warranty
  • 100-night trial period
  • Free shipping and returns
  • Long list of certifications including GOTS, Oeko-Tex, Eco-Institut, Greenguard Gold, and several others.
  • Flippable (2 firmness options in 1 bed)
  • Great for virtually any type of sleeper
  • Pressure relieving and supportive
  • 10-year warranty
  • 100-night trial period
  • CertiPUR-US® certified
  • Might still trap heat
  • Complaints about off-gassing and fiberglass

Wayfair sends a bunch of mattress brands but we think their own, Wayfair Sleep, has one of the best mattresses for bunk beds. Specifically, their Two-Sided 8-Inch Memory Foam Mattress. 

As you might have already guessed, it’s a flippable (or reversible as the brand calls it) 8-inch mattress. It has 3 layers. From the top-down:

  • 2 inches of charcoal infused memory foam
  • 2 inches of ventilated cool foam, and
  • 4 inches of high density base foam

With the memory foam layer on top, the mattress feels medium which is great if you’re petite. Flip it over and you a firmer mattress which can be an awesome choice for both average weight and heavyweight sleepers. 

Because of the memory foam layer, the mattress is great for pressure relief. The holes on the middle layer also make this mattress more breathable. Although, it might still sleep hot for some of you. The bottom layer adds support and durability. 

Before you place your order, however, note that most of this mattress’ complaints are about terrible off-gassing which is ironic considering the top layer is infused with charcoal. So, if you don’t have a place to air it out for a few days, you might want to consider a different mattress.

Some customers also complain about the fiberglass fire retardant so be sure to check the integrity of the cover. Lastly, you won’t be able to buy this anywhere else except Wayfair’s website. 

Other features of the Wayfair Sleep Two-Sided 8-Inch Memory Foam Mattress:

  • 10-year warranty
  • 100-night trial period
  • Free (2-day) shipping and returns
  • CertiPUR-US® certified
  • Uses 100% natural latex, cotton, and wool
  • 2 thickness options (7 and 9 inches)
  • Flippable (different firmness levels on each  side)
  • Uses both Dunlop and Talalay latex
  • Breathable, durable, pressure relieving, and supportive
  • 20-year warranty
  • 120-night trial period
  • GOTS, Oeko-Tex, Eco-Institut certified
  • Lower priced latex but still pretty expensive
  • 7-inch model not available on Amazon
  • Heavy

When you’re looking for a latex mattress, there are a few brands that will almost always come up in your search. One of them is Latex for Less.

True to their name, they do sell some of the more affordable latex products in the business but the fact of the matter is that latex is almost always going to be more expensive than memory foam. 

We think it’s well worth it though. All the latex foams here are 100% natural, the cover is 100% cotton, and the material used as a fire retardant is 100% wool, too.

So, if you’re worried about allergies from synthetic materials used in cheaper foams, this should help ease some of that concern. Plus, you’re also paying for the lengthy 20-year warranty and 120-night trial period. 

With that said, The Latex for Less mattress comes in 2 thickness options: 7 and 9 inches. What’s weird to us is that Amazon only seems to be carrying the 9-inch model. If you wanted to get the thinner version (which is what we recommend for bunk beds, by the way), you’re going to have to directly visit their website. 

Anyhow, it’s a flippable mattress with each side feeling different. One side uses Talalay latex which has a medium feel to it while the other side uses Dunlop latex and feels firmer.

What’s so great about this is that if you’re not comfortable on 1 side, simply flip it over and it’s like you’re sleeping on a different mattress. 

Latex is also naturally breathable and durable. On the right firmness level, it’s pretty darn pressure relieving and supportive, too.

Plus, it’s a responsive material, so you won’t get that stuck-in-the-mud feeling you get with memory foam. It’s quite heavy though, so you might need help changing the sheets on the top bunk. 

Other features of the The Latex for Less Latex Mattress:

  • 20-year warranty
  • 120-night trial period
  • Free shipping and returns
  • GOTS, Oeko-Tex, Eco-Institut certified
  • Affordable
  • Advertised specifically for bunk beds and children
  • Durable tempered steel springs
  • Supportive and breathable
  • 10-year warranty
  • 30-night trial period
  • CertiPUR-US® certified
  • Might be too firm for some
  • The bounciness of the springs might be a hazard if placed on the top bunk
  • Thin comfort foam layer

Linenspa is a brand known for selling affordable mattresses and this 6-inch innerspring is no exception. For a twin, you’re looking at a mattress that sells well under 100 bucks.

Not only that, it’s specifically advertised for bunk beds, growing kids and toddlers, and even teenagers! Sounds great, eh? 

The springs used in these mattresses are tempered steel, so we’re quite confident in their durability.

Innerspring mattresses are also innately supportive and breathable. It also has a firm feel to it which we generally recommend for bunk beds but if you or your child wants softer mattresses, this might not be what you’re looking for. 

Innersprings are also naturally bouncy. Although we do admit that’s fun, it can also be a hazard when you have a child that might decide to make the top bunk his/her own trampoline. That being said, we urge you to only have this mattress on the lower bunk if you decide to buy it.

Also, the foam layer on top of these springs are thin. Too thin, in fact, that we’ve read customers complaining about how they can feel the springs when they sleep. This can easily be fixed by using a mattress pad though. 

Other features of the Linenspa 6-Inch Innerspring Mattress:

  • 10-year warranty
  • 30-night trial period
  • Free shipping and returns
  • CertiPUR-US® certified
  • Multiple firmness options (6, 8, 10, and 12). We recommend the 6-inch model. 
  • Firm but pressure relieving
  • Charcoal and gel helps reduce heat, moisture, and odor
  • Sleeps cooler than regular memory foam
  • 10-year warranty
  • 30-night trial period
  • CertiPUR-US® certified
  • Customers complaining of mattresses not inflating to their full thickness
  • Complaints of torn covers releasing fiberglass shards
  • Confusing shipping and return policies

Signature Sleep’s Flex mattress comes in multiple thickness options: 6, 8, 10, and 12. For bunk beds, we recommend the 6-inch variant but, depending on the amount of headspace you have and the height of your handrails, you may opt for the 8- and 10-inch options. However, for the purposes of this list, we’ll be reviewing the Flex 6-Inch model. 

Having said that, the 6-Inch model is the firmest and lightest of the bunch but it also has the least amount of layers: charcoal and gel infused memory foam, convoluted foam, and high density support foam. 

The charcoal and gel help wick away heat and moisture odor away from your body while also minimizing any odors. This not only improves your sleep but also prolongs the life of your mattress by cutting the risk for developing molds.

Per Signature Sleep, the convoluted foam is there for pressure relief. We think it helps but more than that, it also helps facilitate airflow. The pressure relief is more of the memory foam’s job. Lastly, the dense support foam adds, well… support, but it’s also there to act as a durable base. 

If you choose to buy this mattress, do make sure to check its thickness as well as the condition of the cover after a couple of days.

From the customer reviews we’ve read, a bunch of them received mattresses that didn’t inflate all the way or had torn covers that released the fiberglass fire retardant. If this happens to you, make sure to return it for a full refund or get it replaced before the end of the 30-night trial period. 

Other features of the Signature Sleep Flex 6-Inch Charcoal Gel Memory Foam:

  • 10-year warranty
  • 30-night trial period
  • Shipping and return fees are a pain to figure out. It may/may not be free. 
  • CertiPUR-US® certified
  • Affordable
  • Multiple thickness options (we recommend the 6-inch model)
  • 6-inch model is the firmest
  • Light
  • Pressure relieving and supportive
  • 10-year warranty
  • 100-night trial period
  • CertiPUR-US® certified
  • Might have been better with a thicker memory foam layer
  • Multiple complaints about off-gassing
  • Removing cover might also release shards of fiberglass

When potential buyers look for affordable mattresses, Zinus almost always comes up as a strong option. Coincidentally, most manufacturers with budget-friendly mattresses are also the ones with relatively thin 6-inch options that are great for bunk beds — and Zinus is no exception. 

Having said that, the Zinus Green Tea Memory Foam Mattress is one of their most popular mattresses.

It has multiple thickness options — 6, 8, 10, and 12 inches — but we think the 6 inch option is the best for bunk beds. 8 and 10 inches can work, too, but you need to measure your headspace and handrails first. 

Anyhow, the 6-inch model is also the firmest which makes it even better for bunk beds.  However, it also has the least amount of layers with just an inch of memory and 5 inches of dense support foam.

We’d love this mattress more if the memory foam layer was thicker but it still feels pretty good. It’s also light, so propping it up the top bunk and changing the sheets shouldn’t be much of a challenge. 

Like all memory foam mattresses, the Zinus Green Tea relieves pressure. It gets its supportiveness from the dense foam below it.

However, we find it ironic how the foams are supposedly infused with charcoal and green tea to help minimize odors but a lot of the negative customer reviews we’ve seen are complaints about off-gassing.

Also, the cover is supposed to be removable but hear us out… DON’T! Lest you risk releasing shards of fiberglass (a lot of mattress brands use this as a fire retardant). 

Other features of the Zinus Green Tea Memory Foam Mattress:

  • 10-year warranty
  • 100-night trial period
  • Free shipping and returns
  • CertiPUR-US® certified
  • Affordable
  • Medium-firm feel
  • 2 inches of gel-infused memory foam (for pressure relief and temperature regulation)
  • 6 inches of dense base foam (for durability and support)
  • 10-year warranty
  • 100-night trial period
  • CertiPUR-US® certified
  • Might be too firm for petite sleepers
  • May sag prematurely if you’re heavier
  • Heavy
  • Might have issues upon delivery (i.e. molds and defective covers)
  • Shipping and return fees dependent on seller, not Classic Brands

Classic Brands advertises this mattress as the “perfect solution” for dorms, bunk beds, and kids rooms. Now, we don’t think any mattress is perfect but this does look quite the suitable — not to mention affordable — mattress for both top and bottom bunks. 

It has a medium-firm feel to it which, theoretically, feels great for almost everyone.

However, based on the customer reviews we’ve read on Amazon, this might be a little too firm for petite sleepers and may sag earlier than expected if you’re carrying a little extra weight. Although, if you’re average weight, this mattress should do just fine. 

It’s also a little thicker at 8 inches so you might want to check the height of your handrails and headspace, especially if you’re considering this for your kid’s bed.

That being said, the top 2 inches are from gel-infused memory foam which helps relieve pressure while regulating temperature. The bottom 6 inches are for a high density base foam for durability and support. 

There are a few things you might want to watch out for though. First, it’s a heavy mattress so be careful when you’re changing the sheets on the top bunk. Second, check the integrity of the mattress right after you receive it.

Some customers reported that they received mattresses that are already growing molds and a few others more are complaining about the how their covers have tears in them which are releasing shards of fiberglass. In this case, return your mattress as soon as possible or before the 100-night trial period ends. 

Other features of the Classic Brands Cool Gel 8-Inch Gel Memory Foam Mattress:

  • 10-year warranty
  • 100-night trial period
  • Classic Brands doesn’t sell their mattresses directly. So, shipping and return fees for your mattress is to be determined by whoever you buy it from.

Things to consider before buying mattresses for bunk beds

We’ve shown you what we think are the best mattresses for bunk beds, but let’s be honest — you probably still unsure about which mattress you need to choose. 

To help you pick a mattress, here are a few things we think you should consider:

Are you or your child allergic to anything?

Because if you are, sleeping on a mattress that might trigger an allergic reaction is way too risky, especially if it’s concerning children. 

Latex, although fairly more expensive, is typically what we recommend here because it’s innately hypoallergenic, antimicrobial, and dust mite-resistant. 

Regardless of what type of material you choose though, a lot of today’s mattresses, especially the more affordable ones, use fiberglass as a fire retardant.

This can be harmful to anyone who inhales it, so be sure to check the integrity of your mattress’ cover the very same day you receive your package. If you notice even the slightest tear, request a replacement immediately or return the product and ask for a refund.

How much headspace do you have? How tall are your handrails?

Again, this goes back to safety. Particularly for the person sleeping on the top bunk, the height of the handrails are extremely important. 

I mean, imagine having a bad dream and you’re rolling around trying to wake up. Having close to nothing preventing you from falling from 6 feet off the ground is going to be dangerous. Not having enough headspace can be risky, too, but it can also make anyone feel claustrophobic. 

Having said that, what you need to do is measure your headspace and handrails and determine how thick your mattress needs to be. As already mentioned, a 6-inch mattress would probably be best for standard bunk beds but if yours allows for thicker mattresses, that’s for you to figure out. 

What size mattress do you need?

Standard bunk beds require twin-sized mattresses. If that’s what you have, that’s an easy decision. 

However, modern bunk bed designs requiring different sized mattresses are quickly becoming more and more popular.

One of the most common modern designs we’ve encountered are bunk beds having larger, full-sized dimensions for the bottom bunk while the top bunk has smaller, twin-sized dimensions. Others even have trundle beds underneath the bottom bunk and that might be a different size, too. 

In any case, always double check the dimensions of your bed so you can also order the right sized mattress. 

How firm do you or your child prefer your mattresses?

To us, mattresses for bunk beds need to be innately supportive. But, at the end of the day, firmness (and the support and pressure relief that comes with it) is subjective. YOU decide what feels best to YOU. 

Generally though, a mattress that’s rated medium-firm should do well for nearly everybody. The question is, when should you consider firmer or softer mattresses? Here’s our answer: 

Get a firmer mattress if…

You’re carrying extra weight or are a back/stomach sleeper. Let’s start with weight. 

Packing extra pounds of weight means you’ll also be pressing on your mattress with more force. If your mattress is too soft (and therefore unsupportive), you’ll sink in way too much and mess up your back’s proper alignment. 

The same concept pretty much explains why you need firmer mattresses if you sleep on your back or stomach — too little support and your hips sag further than the rest of your spine and place it in an abnormally bent position.

Get a softer mattress if…

You’re petite or are a side sleeper. 

For weight, it’s basically just the opposite — you won’t be putting a lot of pressure on your mattress. So, if you’re sleeping on a firm, or maybe even medium firm mattress, you might feel like you’re sleeping on hardwood floor instead of sinking into the foam. 

As a side sleeper, you’re going to be putting a lot of pressure on your hips and shoulders. You’re going to want a softer mattress to relieve pressure on these parts of your body but not too soft that your spine sinks into the mattress, too.

Maintaining your mattress for bunk beds

School and raising a child can both be extremely expensive. Unfortunately, so are mattresses. So, if you’ve already found the right mattress for you or your child’s bunk bed, you’re going to want it to last as long, if not longer than it should. 

The steps for maintaining your mattress are fairly simple, such as regularly changing your sheets, rotating your mattress, vacuuming every so often, and a few others more. If you want to learn more about this, we wrote a guide on how to clean your mattress. Go check it out


In a nutshell, we think the Sleep On Latex Pure Green Natural Latex Mattress is the best mattress for bunk beds, in large part, because it uses 100% natural latex, cotton, and wool.

These materials reduce the chances of you and/or your child getting allergies. It can be expensive and heavy for some people though but we think it’s worth it because it’s durable, breathable, comes in multiple thickness and firmness options, and has a long trial period and warranty. 

With that said, there are other mattresses here to choose from just in case the Sleep On Latex Pure Green Natural Latex Mattress isn’t your cup of tea.

If neither of them still fit your preferences, then we at least hope the short guide on things to consider before buying a mattress for bunk beds helps you find what you’re looking for.
