Best Mattress for Bunk Beds of 2023

Bunk beds are the perfect space savers for kids’ rooms or college dorms. These stackable beds optimize space, allowing more room for play areas or other furniture. However, you have to be careful when buying bunk bed mattresses. Mattresses for bunk beds should not be too thick or heavy. Otherwise, they pose safety concerns.

In this article, we discuss the important criteria for choosing the right bunk bed mattress and recommend our top picks for saving space. We also go over other things you should consider before buying the best bunk bed mattresses for your needs.

Important Criteria for Bunk Bed Mattresses

To avoid accidents or injuries from rolling off the bed, federal laws have regulated guidelines mandating guard rails on the upper bunks. According to the United States Consumer Product Safety Commission (CPSC), the top of the guardrails must be no less than 5 inches above the top of the mattress.

Before buying your bunk bed mattress, measure the distance between the top of the guardrail and the bed frame. This measurement determines how thick your mattress can be to safely fit the upper bunk.

On a too-thick mattress, sleepers may bump their head on the ceiling or on the upper bunk. Too heavy mattresses can exert too much pressure on the bed frame, potentially damaging it.

The Amerisleep AS2 is our top recommendation because its 12-inch thickness is suitable for a bunk bed. The surface is medium-firm with a focus on targeted support, while also being comfortable enough for a restful night’s sleep.

Amerisleep mattresses are available in all standard sizes, including the twin, twin XL, and full sizes commonly used in bunk bed frames. They are light enough for bunk beds with the twin mattress weighing about 45 pounds, twin XL and full weighing 49 pounds and 63 pounds respectively.

The Amerisleep AS2 includes a 100-night sleep trial and a 20-year warranty, covering manufacturing defects and sags greater than an inch. Also, Amerisleep’s mattresses are shipped free within the continental US.

How Lying Down Feels

The plant-based foam layer that forms the top conforms to your body, relieving pressure points, while the sturdy Bio-Core® base layer prevents mattress sinkage beneath your back or abdomen. This sinkage could otherwise misalign your spine, causing back, neck, or muscle pain.

The mildly firm feel of the AS2 is perfect for back and stomach sleepers because it reduces the chances of spinal misalignment. This layer, made with strong polyurethane foam, also increases mattress durability by preventing sags.

People have bought the AS2 for their childrens bunk beds and the reviews praise this choice. Here is what some had to say:

GEO: I knew I would like sleeping on a premium foam mattress, and I was right ! Being tired of the same old coil spring ones, time to upgrade…I already use foam pillows, and my daughters bunk bed with trundle has two full foam, one single mattress, I have spent a little time on the main full one, it was comfortable, even not being a major, premium one.

Happy Momma: I purchased my first Amerisleep bed around 5 years ago. I’ve had nothing but excellent sleep since. So much so, that I purchased 2 more beds for my 6 and 7 year old. They wanted beds as comfy as mommy’s bed

Mom: Great mattress for both my kids room. Very happy with the purchase.

Inside the Mattress

The AS2 includes 2 inches of plush Bio-Pur®, 3 inches of Affinity foam, and 7 inches of firm Bio-Core® support layer wrapped in a soft, breathable fabric. This mattress cover is designed to wick away moisture, keeping you cool as you sleep.

The eco-friendly Bio-Pur® comfort layer is made by substituting a certain portion of the petroleum with natural plant oils, so the mattress sleeps cooler than traditional memory foam beds. These plant-based foams are CertiPUR-US® certified, so they are free of chemicals like CFCs, formaldehyde, phthalates, PBDEs, and are low in volatile organic compounds (VOC) emissions. Low VOCs means the off-gassing odors are minimal.

The second layer is the transition foam, Affinity with HIVE® technology. The hexagonal cutouts that make up this innovative sleep technology create more flexible cushion in the shoulders and hips, while the head, back, and feet areas have cutouts spaced for greater support.

As we mentioned, the Bio-Core® base layer provides support and structural ingretity.

The Zoma Start is slimmer than many other mattresses, standing 10 inches tall. It’s the perfect weight for bunk beds because excess weight can cause structural damage to the bed or cause it to collapse. We recommend this mattress because it offers a cool sleeping experience and supportive construction.

This CertiPUR-US® certified mattress is manufactured in the United States and ships free to the contiguous 48 states. The Zoma Start includes a risk-free 100-night sleep trial. It’s also backed by a 10-year warranty.

How Lying Down Feels

The cooling gel dissipates heat, keeping you cool through the night. Typical bunk bed sleepers are children and young adults, and they tend to feel hotter than adults or seniors. Their physically active lifestyle often makes them hot sleepers, so they can benefit a lot from this gel memory foam comfort layer.

Its medium feel appeals to a vast variety of sleepers, including side, back, and combination sleepers.

Some of the thousands surveyed on the Zoma Start had this to say:

Parth P: It is a phenomenal mattress especially for the price!

Billy K: Kind of firm waking up with shoulder pain occasionally

Xiao C: It’s of good quality overall. Came with proper packaging and easy to set up. It was a bit too soft for my back the first night, but after that I experience no back pain sleeping on it.

Inside the Mattress

The Zoma Start contains an inch of gel memory foam, an inch of Reactiv™, and 8 inches of Support+, all encased in a knit fabric cover that wicks away heat.

As we mentioned, the gel memory foam layer is perfect for sleepers who need to stay cool at night, particularly in warmer climates.

The next layer is Reactiv™, a bouncy material that prevents the body from sinking into the mattress. This responsive layer makes it easier to switch sleep positions.

The Support+ base layer reinforces the upper layers and prevents indentations on the surface.

The Vaya Mattress is a good choice for many sleepers because it offers high-quality comfort at an affordable price.

Vaya’s twin, twin XL and full sizes are slightly heavier than AS2 and Zoma mattresses. A twin bed weighs 54 pounds, a twin XL weighs 68 pounds, and a full weighs 78 pounds so check the weight limit of your bunk bed before buying the mattress.

All Vaya mattresses includes a risk-free 100-night sleep trial and a 10-year warranty. It’s made in the USA and ships free to all the lower 48 states.

How Lying Down Feels

The Vaya Mattress feels lightly soft as sleepers stretch out, with the support keeping them comfortably buoyed on the surface. The breathability of its top and cover fabric also enables swift heat dispersion, staying cool at night.

Customers who chose the Vaya have overall been very happy. Here is what some had to say:

Karen P: Very well made mattress, and I liked the idea of the hybrid. But unfortunately, it was much to firm for me. I tried to get used to it, but my hips are just too painful.

Steven M: Mattress came right on time and is very comfortable

Heather B: Excellent quality for such a price. Definitely buying it again!

Inside the Mattress

This medium mattress contains 3 inches of Vaya Foam and 9 inches of base foam, wrapped in a polyester blend cover. This soft fabric improves airflow within the mattress for a cooler sleep.

The top comfort layer is 3 inches of Vaya Foam, a latex-like material that conforms to your body but does not trap heat like traditional memory foam. This responsive foam does not make you feel “stuck” in the mattress. The base layer is 9 inches of sturdy foam to prevent mattress sinkage and sag.

The foams used in the Vaya Mattress are CertiPUR-US® certified, indicating that it is free from harmful chemicals and safe for consumers.

Side sleepers may struggle a little when it comes to choosing a bunk bed mattress, as many of the softer mattresses are simply too thick and heavy for the frame. Mattresses like the Nolah Original 10, though, are lightly soft without being too plush, providing a balanced feel that whisks away tension in the shoulders and hips.

Like other Nolah mattresses, the Original 10 ships free and comes with a 120-night trial period and a lifetime warranty. The sleep trial can be removed as you checkout, perfect for budget shoppers who want a deeper discount.

How Lying Down Feels

Overall, the Nolah Original offers a good balance of comfort and support, making it a snap to wake up feeling refreshed and pain-free. The AirFoam™ in the top layer of the mattress is excellent at providing pressure relief and preventing overheating, which can be especially beneficial for people who sleep hot or live in a warmer climate.

Plenty of customers love the Nolah brand, children and adults alike, whether it is a bunk bed or an adjustable bed, Nolah has a mattress for you. Here is what some had to say:

Rebecca H: My online shopping experience was fun and the service was great! In terms of shipping, my purchases arrived on time and well packaged. Overall, I am extremely happy with Nolah! I will definitely shop here in the future!

LeAnn E: Nolah is wonderful! Easy online shopping, received in 7 days. We unwrapped, let it set for weekend and slept on Sunday night, woke up Monday feeling refreshed, ready for week! After 2 weeks, shoulder soreness reduced and sleeping all night, amazing and I would recommend!

Brett C: We were able to make the purchase easy online. Shipping was fast and delivered in great condition as we were told it would be. Fair warning- the King size 15Evolution is a heavy mattress. If you are taking it upstairs you will need 2 people to be safe as the box weighed about 150 lbs I think. We wake up feeling rested and ready for the day. We would do it all over again.

Inside the Mattress

The Nolah Original mattress is an all-foam mattress that consists of three layers of foam, wrapped in an eco-friendly cover of snow-white Tencel™ fabric.

The first layer is made of a cooling Nolah AirFoam™, which is designed to provide pressure relief while also keeping you cool throughout the night.

The second layer is made of a supportive high-resilience foam, which is meant to provide support and prevent you from sinking too far into the mattress.

The third and final layer is a dense base foam, which provides the foundation for the mattress and helps to ensure its durability over time.

Many parents use bunk beds for their children to save space while providing comfort. Kids also often enjoy climbing in out of their bunk bed, finding it a novelty compared to a traditional frame. If you want a mattress suitable for growing children, we suggest the aptly named Saatva Youth.

According to Saatva, the twin size Saatva Youth mattress weighs 45 pounds, the twin XL size is 56 pounds, and the full size is 61 pounds. Make sure your bunk bed frame can suitably accommodate the weight of this 10-inch mattress before purchasing it.

How Lying Down Feels

What makes the Saatva Youth a special mattress is that it has two distinct sides, each one meant for a different age range of children. One side of the mattress is firmer, while the other is softer. The side for children aged eight through twelve is designed to support larger bodies yet gently cradle them, rather than the supportive side for children ages three to seven.

While there are limited reviews on the Saatva Youth, the ones they have on their website are promising:

Meagan W: Purchased this for my son with Autism. Love that if one side is too firm all I have to do is flip it to meet his ever changing needs. It is super durable! He absolutely loves it. The company’s customer service is phenomenal and quick to respond to any issue.

Natallie S: My toddler loves this mattress. He’s been sleeping better than ever. It’s very comfortable.

James: We’ve bought 2 Youth mattresses at this point. Our kids both sleep great. My daughter’s sleep used to be awful on her cheap big box furniture store mattress and her sleep greatly improved since we got the saatva youth.

Inside the Mattress

Not only is the mattress cover made with organic cotton, delivering a cooling and breathable feel for a child’s instant comfort. This mattress for kids also has an antimicrobial treatment with a botanical compound, creating a healthy barrier against a wide range of allergens.

Beneath the organic cotton cover, a layer of comfort foam provides pressure relief and contouring for a comfortable night’s sleep. For younger children, the mattress features a five-zone pressure relief system that ensures optimal cradling and support. Meanwhile, older kids will benefit from a more buoyant and supportive comfort layer that accommodates their extra weight.

Regardless of what side is facing up, the Saatva Youth mattress relies on supportive coils with a reinforced foam perimeter. This creates a durable and bouncy support system that can withstand even the most active children.

The mattress also relies on a waterproof finish and an internal waterproof barrier. This ensures that your child’s mattress stays clean and dry, providing protection against the spills and accidents that can be inevitable with kids. Even so, careful parents may want to pair the Saatva Youth with a mattress protector.

Parents and their children can also rest secure knowing Saatva mattresses contain no fiberglass, using natural wool and thistle instead.

On a sweltering summer night, it can be all too easy to feel the rising heat build up around your bunk bed frame. With its cooling gel infusions and advanced cover fabric, the Bear Original is our recommendation for hot sleepers who need a cooling bunk bed mattress.

How Lying Down Feels

The Bear Original mattress has a unique feel that is generally described as medium-firm. The mattress is designed to provide a balance of support and pressure relief, but some find it has a slightly firmer feel than other mattresses in the same category. The mattress also has a bit of bounce, making it easy to move around on and change positions throughout the night.

One of the standout features of the Bear Original is its cooling properties. The mattress is made with a special cover that is designed to wick away heat and moisture, keeping users cool and comfortable throughout the night. Many find that they no longer wake up feeling hot and sweaty since switching to the Bear Original.

While Bear Mattress does not have as much of a long of a track record of reviews as some of our other mattresses, we found plenty with something to say, here are a few:

Doug D: I’ve slept on BEAR’S Original — Hybrid for a month. I’ve got my aches and pains, but some are now less. I don’t toss & turn nearly as much. I’ll never looking back on my number bed – ugh! This bear gets more rest in my new “den.” I’m very glad I didn’t get a mattress thicker than the 10″ this comes in.

Kelly A: Bed was of good quality, but more firm than medium-firm for my partner and I (back/side sleeper; side/stomach sleeper). Return process went pretty smoothly. Would recommend for those looking for a nice firm mattress!

Cynthis S: Great for growing athletic teenager! My growing son loves and he’s sleeping much better

Inside the Mattress

Starting from the top, the mattress surface is made of a Celliant cover that is designed to help with recovery and promote better sleep by converting body heat into infrared energy. This cover fabric is also highly breathable and helps to keep the mattress cool throughout the night.

The comfort layer is gel memory foam, which offers pressure relief and added comfort. This layer conforms to the body to provide a comfortable, personalized sleeping experience. The gel infusion also helps to dissipate heat, keeping the sleeper cool and comfortable.

The next layer is made of responsive transition foam that helps to evenly distribute weight and promote spinal alignment. This layer of Bear Dynamic Foam offers support and helps to prevent the sleeper from sinking too far into the mattress.

Finally, the base layer is made of high-density support foam that provides overall support for the mattress and ensures the mattress’s longevity. This layer also adds durability and stability to the mattress.

All of the layers are CertiPUR-US® certified, meaning they are free from harmful chemicals and toxins. The mattress is also certified by GREENGUARD Gold. The GREENGUARD Gold certification is a special program that helps make sure products made for indoor spaces are safe and healthy by checking that they meet strict chemical emissions limits.

Bunk beds aren’t just found within the home, and you may need a thinner and more compact one if you’re looking to outfit an RV or camper with a new mattress. The Brooklyn Bedding Dreamfoam Essential mattress comes in a wide range of specialty sizes, along with varying thicknesses and firmnesses. This makes it easy to choose a mattress that minimizes drag on a vehicle.

You can also go with the Dreamfoam Essential if you need a mattress under $500 for a bunk bed. The Dreamfoam Essential ships free and comes with a 120-night trial and a 10-year warranty.

How Lying Down Feels

The feel of the Dreamfoam Essential depends on the thickness you choose, with the softer feels tied to the thicker mattresses. For adults that plan to sleep on a bunk bed mattress night after night, we recommend the 10-inch mattress with a medium-firm feel or a 12-inch mattress with a medium feel from Brooklyn Bedding.

Parents looking for bunk beds for their kids, and campers looking for RV bunks both love this mattress. So even if you are looking for the “other kind of bunk bed” Brooklyn Bedding has you covered:

Oscar W: I bought this mattress for my kids bunk bed. I like the firmness of the mattress, but my wife really dislike the smell. It is strong and lingered for weeks. People who are sensitive to the smell should be aware.

Michael A: We were glad to find a perfect fit for a lower bunk that is 48×74, a size we hadn’t heard of previously. It is a quality mattress at a good price and we are happy with it. Seems a little firmer than expected.

Randy S: Its difficult to find the size we needed for our RV bed (Olympic Queen), but after buying mattresses for the kids bunk beds, and them being a lot more comfortable than our bed, we had to get one for ourselves. Highly recommended, we have 4 of these now and we love them!

Inside the Mattress

The Dreamfoam Essential mattress construction varies depending on the height you choose, with thicker models containing more conforming material.

For the 6-inch mattress, you can expect to find 2 inches of gel swirl memory foam resting on a 4-inch base foam. The 8-inch option is similar, featuring 2 inches of gel swirl memory foam on top of a 6-inch dense base foam. If you opt for the 10-inch model, you’ll enjoy 2.5 inches of gel swirl memory foam supported by 7.5 inches of support foam.

For those seeking a taller mattress for a bunk bed, the 12-inch model adds a transition layer. This mattress features 2.5 inches of gel swirl memory foam on top of 2 inches of VariFlex transition foam layer and 7.5 inches of support foam.

Lastly, the 14-inch model boasts the thickest comfort layer with 3 inches of gel swirl memory foam on top of 3 inches of VariFlex transition foam layer and 8 inches of support foam. However, this is likely too thick for a bunk bed.

Another bunk bed mattress for kids that we can’t pass up mentioning is the Helix Kids mattress. One side supports growing bodies aged 3 to 7, while the reverse side has memory foam to cradle children ages 8 to 12. Pairing poly-foam with eco-friendly cover fabric, this mattress serves as an excellent hypoallergenic bunk bed mattress.

How Lying Down Feels

Like many mattresses for children, the Helix Kids has two sides with different feels to offer what kids need at different points in their young lives. The firmer side is perfect for children just starting out away from a crib, while the reverse side has a softer feel to cradle children on the cusp of their teen years.

Parents looking for bunk beds for their kids are completely in love with this mattress. If you don’t believe us, here are some reviews:

Erika S: This is great for a top bunk for my kids since it is within the recommended mattress height and it comfortable. I have slept on it myself many nights. I generally prefer very firm mattresses, so it is a little soft for my preference, but my sleep quality is great.

Venessa T: I bought 1 full and twin size for bunk beds. My son loves sleeping on his bed and pillows! It’s very comfortable and shipping was fast! I love that the kids beds will last a long time due to the age ranges of each side.

Melea N: We love this mattress. Both our boys loved their new mattresses. It’s a little taller than I normally would like for a bunk bed but it still lower than the top bunks frame. Reading a book to my boys with them before bed is way more comfortable in my back and my boys say their mattress is comfy too.

Inside the Mattress

While many of our recommendations feature cotton covers, the Helix Kids mattress has a cover fabric of Tencel fabric to maintain coolness. Not only is it eco-friendly, as it’s made from eucalyptus fibers. Helix has also treated this fabric with AEGIS® Microbe Shield to keep the bed pristine by fighting odor-causing bacteria. And to protect against accidents and stains, there’s RUCO®-DRY BIO NPE, a plant-based water-repellant finish.

The firm side of the mattress has dense, supportive, high-grade polyfoam, while the flip side has plush gel-infused memory foam. The support core of the Helix Kids mattress for both sides is a series of wrapped steel coils, isolating movements while still providing kids with an enjoyable bounce.

The original Layla Memory Foam Mattress is a flippable mattress with a twist, as each side of the bed has a different firmness, both capable of comfortably supporting adult sleepers. If you can’t decide between a soft or firm mattress for a bunk bed, why not enjoy both?

How Lying Down Feels

The Layla Memory Foam Mattress is noteworthy for its flippable firmnesses, meaning you can flip it over to access a different firmness level. One side of the mattress is soft, while the other is firm. The soft side is designed for side sleepers, while the firm side is ideal for stomach and back sleepers.

Many people felt this mattress was either too thick or not thick enough, so keep thickness in mind when ordering this mattress:

Daren B: Thanks for allowing me to try the Layla. I personally don’t believe its thick enough. It hurt my lower back and it felt like something was sticking in it.

Martha R: This bed is so comfy it’s like sleeping on a thick piece of cotton comforts your body so well.

Taren C: I would like the mattress to be softer and not as thick.

Inside the Mattress

The Layla Memory Foam Mattress is covered with a thermo-gel infused cover that is designed to keep you cool and comfortable throughout the night. Both sides are covered with this cooling fabric.

Starting from the soft side, the top layer is made of copper-infused memory foam. This layer is designed to provide pressure relief and contouring support to the body. The copper particles not only deepens the compressive support but it also conducts heat away from the body and keeps microbes from settling in the bed.

The second layer is made of convoluted support foam, called Max Airflow Support Foam. This layer provides support and extra breathability to keep the mattress cool. Only the soft side has this transition layer.

The support core is foundational foam, with minimal bounce, motion transfer and support for sleepers. This layer ensures its durability.

The reverse firm side is a thinner layer of copper-infused memory foam.

The Latex for Less Mattress is an ideal choice if you are looking for an organic bunk bed mattress. This double-sided bed gives you the option to choose from a medium or a firm side. If your firmness preferences change with time, simply flip the mattress to suit your needs.

Like our other recommendations, Latex for Less mattresses are also made in the US. They include a risk-free 120-night sleep trial and a 20-year warranty.

These organic latex mattresses are available in two thickness options, 7 and 9 inches, but the thinner mattress is meant for those who weigh less than 100 pounds. Ideally, they are good for children in the 6-10 age range. However, check the weight limit of your bunk bed because latex mattresses are heavier than other foam mattresses.

How Lying Down Feels

As we mentioned, the Latex for Less flippable mattress can be switched between medium and firm feels. The medium mattress is more generally comfortable, but the firmer feel may be well-suited for a younger child.

Parents love the Latex For less, whether for a bunk bed or not, people love this mattress. Check out the reviews yourself:

Andrea R: We bought a twin and full mattress for our son’s bunk bed. It’s been a couple months now and we’re all very happy with the purchase. My almost 4YO sleeps regularly through the night on them, and when my husband and I lay on them, we are very comfortable. I feel that this is a great product for the price, especially given that it’s made in the USA of natural materials

Dina R: Best mattress ever, highly recommend! My sleep has improved so much since getting this mattress, got it for 3 of my kids too, it was a splurge but no regrets

Judith B: I purchased three mattresses and although my husband and I have not have the chance to use ours, we have tried our kids and they are terrific. They feel wonderful! And the peace of mind I have knowing my kids are not sleeping on a bed of armful chemicals is immeasurable.

Inside the Mattress

The Latex for Less Mattress contains an organic cotton cover, a natural wool fire barrier, and natural latex foam harvested from the sap of rubber trees. The GOTS-certified (Global Organic Textile Standard) cotton cover ensures the fabric is made with more than 70 percent organic fibers, which has been responsibly farmed and manufactured.

The 100 percent natural wool fire barrier meets federal safety standards without using harsh chemicals. Organic wool also wicks away moisture, keeping sleepers cool in bed.

The next layer is OEKO-TEX® certified natural Talalay latex with a medium feel, followed by Dunlop latex with a firm feel. Both Talalay and Dunlop latex are made from the sap of rubber trees, but the manufacturing process varies, leading to a slight difference in texture. Talalay latex is more bouncy, while Dunlop latex is more springy. The OEKO-TEX® certification ensures minimal use of chemicals while making the foam.

Beneath the firm Dunlop latex layer lies the natural wool flame barrier and cotton cover layers, making it double-sided. That way, even when you flip the mattress, you still sleep on the cotton cover while experiencing the firm feel of the Dunlop latex layer. If you want to sleep on the medium side of the bed, flip it back so the Talalay layer lies above the Dunlop layer.

Best Mattress for Bunk Beds Highlights and Comparison

Factors to Consider When Buying a Bunk Bed Mattress

When you’re buying a bunk bed mattress, chances are you will need two beds instead of one. If you’re working with a twin XL size frame, you may even be able to buy a split king mattress and put each half in the top and bottom bunk.

While looking for an affordable mattress for the money, make sure you don’t compromise on quality. Also, ensure the mattress isn’t too thick or heavy so it’s compatible with bunk bed frames.

To find an affordable and comfortable bunk bed mattress, such as a mattress under $1000, consider the following factors.

Bunk Bed Type

The first step before buying a bunk bed mattress is to determine the number of mattresses you need, which depends on the type and the dimensions of bunk bed frame you buy.

Here, we go over the different types of bunk bed styles available on the market. The type that is better for you can depend on your purpose. For example, one you intend to use as an occasional-use mattress for guest room can be different than one you intend to use nightly.

Standard Bunk Bed

Mattresses Needed: 2

A standard bunk bed includes two bunks of the same size stacked one over another. Most standard bunk beds are available in twin and twin XL sizes, but you may find some in full sizes as well. The bunks are detachable, so use them as two separate beds when needed. It’s a great choice for siblings who eventually shift to different rooms as they grow up.

Standard Loft Bed

Mattresses Needed: 1

A standard loft bed needs a mattress for the upper bunk, while the place beneath it serves as a storage area or workstation. This open space is usually 4 feet tall, providing enough room for a chair or sofa to fit in it.

Loft beds often include a pull-out desk and cabinets in the open space. They are commonly used in college dorms or a teenager’s bedroom. You will just want to make sure that as a mattress for a teenager, it accommodates a larger body with a corresponding mattress thickness.

Triple Bunk Bed

Mattresses Needed: 3

A triple bunk bed is a taller variation of the standard bunk bed, with three bunks of the same size stacked on top of each other. In some triple bunk beds, the middle bunk may be placed perpendicular to the lower and upper section.

This style of triple bunk bed takes up more space than the standard triple. Like standard bunk beds, even triple bunk beds are detachable for use as three separate beds.

Triple Loft Bed

Mattresses Needed: 3

In a triple loft bed, there are two upper bunks joined at a perpendicular angle, with an open space beneath one of them and a lower bunk beneath the other. Like standard lofts, the open space beneath the triple loft is also 4 feet providing sufficient space for an individual to sit and study. They need more space than a triple bunk bed and are usually placed in the corner of the room to optimize the floor area.

Twin-Over-Full Bed

Mattresses Needed: 2

Twin-Over-Full bunk beds are a good option for families with three children who don’t have bigger rooms or rooms with high ceilings for a triple loft or a triple bunk bed. Two children can comfortably sleep on the lower full size mattress, while the third child can sleep on the upper twin bed.

There are also other size variations, such as twin XL-over-queen frames, if you need more space for your sleeping children.

L-Shaped Bunk Bed

Mattresses Needed: 2

An L-Shaped bunk bed includes two bunks, with one stacked perpendicular to the other. Sometimes, these beds feature pull-out desks, drawers, and cabinets doubling up as a workstation for children. An L-shaped frame can also include a third bed or even a fourth, depending on the design.

Trundle Bunk Bed

Mattresses Needed: 3

Trundle beds offer an innovative way to save floor space because they house a bed in a pull-out drawer beneath the lower bunk. The upper and lower bunks are stacked one over another, like standard bunk beds. This can be perfect for sleepovers and other situations when you need to temporarily accommodate a guest.

Futon Bunk Bed

Mattresses Needed: 1

A futon bunk features a bed on the upper section, with a couch beneath. The couch can be converted to a futon sleeping surface when needed. It serves as a temporary bed for a guest.

Size

Most bunk beds are available in twin and twin XL sizes, the two most compact bed sizes. A twin measures 38 inches by 75 inches and is often used in the kids’ room, while a twin XL is 5 inches longer, measuring 38 inches by 80 inches. The extra legroom in a twin XL comes in handy to accommodate growing teenagers and adults as well.

Twin XL bunk beds are common in college dorms and teenagers’ bedrooms. This is why a twin XL is one of the top choices when choosing a mattress for college students or teens planning to take their new mattress to college.

Some bunk beds are also compatible with full size mattresses. Full beds are wider than twin XL mattresses, but shorter, so they may not be a comfortable option for tall sleepers. They are 54 inches by 75 inches, providing enough room for two children.

There are even bunk bed frames that have large queen or king size beds for the bottom bunk, and smaller bunks up top. These can ensure that multiple children still have plenty of sleeping space without resorting to a triple loft frame.

As a reminder, here are an overview of the standard mattress sizes.

Bunk Bed Mattress Type

There are four main types of mattresses: memory foam, latex, hybrid, and innerspring. Each has its own unique characteristics that make it suited for different types of sleepers and bed frames, including bunk beds.

Memory Foam Mattresses

Memory foam mattresses are made from a high-density, reactive foam that conforms to the shape of your body, offering exceptional comfort and support. They are ideal for bunk beds because they are lightweight and have a low profile, making them easy to move and install on the top bunk.

Latex Mattresses

Latex mattresses are made from natural or synthetic latex and offer a firm yet supportive feel. They are also responsive and durable, making them a good choice for bunk beds. However, they can be more expensive than other mattress types. As latex foam is heavier than memory foam, it may be too much for a bunk bed frame to support.

Innerspring Mattresses

Innerspring mattresses are the traditional mattress that features a coil support system with a layer of padding on top. They are generally less expensive than other types of mattresses and can be a good budget option for bunk beds. However, an innerspring mattress may not provide the same level of comfort and support as memory foam or hybrid mattresses.

Hybrid Mattresses

Hybrid mattresses combine elements of spring and foam beds, with a layer of foam on top of a pocketed coil support system. This combination provides excellent support and pressure relief while still maintaining a level of bounce and responsiveness. They can also be a good choice for bunk beds, but may be heavier and more difficult to move than memory foam or classic spring mattresses.

Bunk Bed Mattress Weight

Knowing the mattress’s weight is crucial when shopping for bunk beds because heavier mattresses can damage the bed frame or cause it to collapse. Most beds have specific weight capacities, which refers to the combined weight of the mattress and the sleeper. If you use a bunkie board, you should also account for its weight.

The weight capacity of the upper bunk in a standard bunk bed may be 200 pounds and the lower bunk may be 400 pounds. If a sleeper weighs 130 pounds, then the weight of the mattress on the upper bunk should not exceed 70 pounds.

The weight capacity on the upper bunks may vary between 200 to 500 pounds for a child’s bunk bed. The weight capacity for an adult bunk bed may range between 500 to 1,000 pounds. Before buying a mattress, verify the weight capacity of your bunk bed.

Remember also that different types of mattresses have different weight ranges. In other words, how much a mattress weighs depends greatly on its materials. Generally, latex is heavier than memory foam and a hybrid mattress is heavier than a traditional innerspring bed.

Bunk Bed Mattress Thickness

What is the best mattress thickness? The answer grows more complicated with bunk beds than with a traditional panel bed. The mattress should not be too thick, otherwise, sleepers on the top bunk may roll over the guardrail and injure themselves. According to federal regulations, the top of the mattress must be 5 inches below the top of the guardrail to ensure the safety of the sleeper.

While avoiding thicker mattresses, make sure you don’t end up buying 6 or 7-inch beds for adults. They are comfortable mattresses for children, but not supportive enough for sleepers weighing above 100 pounds. It’s better to opt for 9 to 12-inch thick mattresses while ensuring the 5-inch gap between the top of the mattress and the guard rail is maintained.

Bunk Bed Mattress Temperature Regulation

Some mattresses may trap heat, leading to sleep disruptions, which affects productivity the next day. To avoid this domino effect, choose mattresses with cooling technologies and breathable covers. Sleepers on the top bunk are more prone to feeling hot, as the hot air rises and hovers near the ceiling.

Bunk Bed Mattress Noise Potential

Foam mattresses are preferred for bunk beds because the coil layer in innerspring and hybrid mattresses can be noisy. This causes sleep disruptions for everyone sharing the bunk bed. Memory foam and all-natural latex mattresses are perfect options, but latex models can be heavier than memory foam mattresses.

Bunk Bed Mattress Firmness Level

Different firmness levels are suitable for various sleeping positions, which is why the mattress industry makes plenty to choose from. Usually, side sleepers feel comfortable on a medium-soft or medium bed because it cushions their shoulders and hips. Soft mattresses are also quite comfortable for side sleepers, but they are often too tall and heavy for bunk bed frames.

A medium-firm or firm mattress is suitable for back and stomach sleepers because it does not compress under pressure. This prevents mattress sinkage beneath the back or abdomen, maintaining spinal alignment.

Combination sleepers are comfortable on a medium bed. They need the perfect balance between firmness and softness to suit their changing sleep positions on a mattress for combination sleepers.

Mattress Warranties and Sleep Trials

Most mattress manufacturers offer a 10 or 20-year warranty covering manufacturing defects or sags. If you notice any of these within the warranty period, most manufacturers will repair or replace your mattress for free or a nominal charge. This is why we strongly recommend you always purchase a mattress with a warranty, even if it’s an occasional-use mattress for a bunk bed.

If you’re not sure about the mattress firmness or type suitable for your needs, buy a mattress with a risk-free sleep trial period. That way, you’ll be able to return the mattress for a full refund within the sleep trial, which typically lasts between 90-100 days. That said, some mattresses with free sleep trials have periods that span a full year.

This is common practice for online mattresses, which shoppers naturally can’t try before they buy. However, even many box stores and mattress showrooms offer lengthy trial periods now.

Who Should Not Sleep on a Bunk Bed Mattress?

Bunk bed mattresses simply aren’t for everyone. There are some people who should not sleep on a bunk bed mattress for safety reasons.

Toddlers and Younger Children

While bunk beds are a popular frame for children, they are generally not recommended for very young children under the age of six years old due to safety concerns. Once they move out of a crib, it’s best to keep younger kids in a toddler bed that’s lower to the floor for a while.

People with Mobility Issues or Medical Conditions

Bunk beds require climbing up and down a ladder to access the top bunk, which can be challenging for people with mobility issues. Seniors or individuals with disabilities may not find bunk beds safe or easy to navigate.

Also, people with certain medical conditions, such as chronic back problems, may not find bunk bed mattresses comfortable as they may not provide adequate support and pressure relief. They may even need an adjustable bed for back pain.

Taller or Heavier Sleepers

Bunk bed mattresses are generally smaller and may not provide enough space or support for taller or heavier individuals, which can lead to discomfort and poor sleep quality. It is possible for a twin XL or a queen bottom bunk to pair with a mattress for taller sleepers, but frames that can safely accommodate the California king or other oversized mattresses are trickier to come by.

FAQs

Can bunk beds collapse?

Yes, they can collapse if they are not assembled properly. Make sure there are no missing pieces and all screws and nuts are tightened well. Plus, maintain the weight capacity as specified by the bunk bed manufacturer to avoid the risk of structural damage or collapse.

Does a bunk bed need a box spring?

No, placing a box spring on the top bunk will make the mattress taller than the safety guard rails, increasing the sleeper’s risk of rolling off the bed. You can place the mattress directly on the slats, but if the slats are more than 2.75 inches apart, put a bunkie board on it to avoid mattress sag. Bunkie boards are designed specifically as a box spring alternative for bunk beds.

How much weight can a top bunk bed hold?

This depends on the bed’s design and the materials used to make it. Usually, solid wood bunk beds are sturdier than particle board or metal, so their top bunks can hold more weight than particle board or metal bunks. Children’s bunk beds can hold anywhere between 200 to 500 pounds, while adult bunk beds can hold around 500 to 1,000 pounds.

At what age is a bunk bed safe?

Children can graduate from a crib to a bunk bed, but they should not sleep on the upper bunk before the age of 6. According to the American Academy of Pediatricians (AAP), children younger than 6-years don’t have the coordination to climb down safely or stop themselves from falling. An estimated 14,600 children under the age of 6 were treated within 2001-2004 for bunk bed fall-related injuries.

Should kids sleep on a firm or soft mattress?

Infants should sleep on a firm mattress because a soft bed could cause suffocation, but toddlers do not need a firm mattress. When deciding on the mattress firmness suitable for your child, consider their body weight. Typically, children who weigh less than 130 pounds are comfortable on a soft to medium bed.  Those weighing above 130 are better suited to a medium or firm comfort level.

Conclusion

Bunk bed mattresses are not much different from regular mattresses. The primary difference is that you have to be extra aware of the mattress thickness and weight, but otherwise you’re free to choose the best mattress for your needs.

A low-profile mattress may not be comfortable enough for a good night’s sleep, while a super-thick mattress may pose safety concerns. Verify the weight capacity of each bunk, check the mattress weight, and ensure the mattress height is 5 inches below the safety guardrail.
