Sleep Foundation
Why Trust Us
Our mission to create a healthier, more well-rested world demands that our product reviews be best-in-class. You won’t find more expertise on mattresses and sleep products anywhere else.
The Sleep Foundation product testing team uses an industry-leading evaluation process paired with real world consumer feedback to come up with objective recommendations so that you can feel confident in your product decisions.
You should make a few considerations when choosing a mattress for your bunk bed. Most of these beds can accommodate twin, twin XL, and/or full size mattresses, but larger sizes will be too wide and long to fit within the bunks. Low-profile mattresses are often ideal, as well. Mattresses that are too thick are often too heavy for bunk beds, and these models can also pose safety concerns on upper bunks. Want to learn about our top mattress picks across all age groups?

How We Tested the Best Mattresses for Bunk Beds
Testing Criteria
Mattresses for bunk beds should do more than just fit the frame. They should also match specific safety, profile, and durability requirements that make bunk sleeping safe and comfortable for any kind of sleeper, regardless of their age or body type. For this category, we made sure to focus on mattresses that are designed to work well in layered sleep spaces without compromising support or longevity. The following factors informed our evaluation of bunk bed mattresses.
Mattress sizes and profiles: Bunk bed frames call for lower-profile mattresses to preserve headroom, maintain structural balance, and ensure safety with several inches of clearance between the mattress surface and bed rails. We prioritized models available in the standard bunk sizes of twin, twin XL, and full, with profiles that meet current safety standards for bunk bed mattresses.
Durability: Bunk beds, especially in kids’ rooms, may see accelerated wear and tear. We evaluated how well each mattress holds up over time, looking for materials and construction that are more resistant to sagging, indentation, and breakdown with regular use.
Bunk bed safety: Safety is central to any bunk bed setup. In addition to proper sizing, we considered features that work with guardrails and ladders, ensuring that mattresses do not compromise these important protective barriers. We also looked at certifications and materials linked to healthier indoor air quality, an important consideration in compact sleep spaces.
How We Evaluated
To evaluate the best bunk bed mattresses, we paired performance data with hands-on testing in our Seattle Test Lab.
We began by reviewing available mattress sizes and profile heights to ensure compatibility with common bunk bed dimensions and guardrail requirements.Then, we analyzed performance scores and sleeper feedback across core criteria, including durability, comfort, and structural integrity.
Each mattress underwent in-depth evaluation, focusing on the following:
- Firmness
- Lumbar support
- Edge support
Based on these findings, we selected the bed mattresses available in sizes and profiles that are compatible with standard bunk bed frames.

Best Mattress Overall: Helix Kids
Best Mattress Overall
8.3/10Test Lab Score
Helix Kids
A flippable hybrid designed for kids 3-12.
Key Details
- Who It’s Best For: Kids 3 to 7 years old (firm side) and kids 8 to 12 (softer side).
- Feel: Medium soft (4) side that hugs the body to relieve pressure points. Medium firm (6) side has a more responsive, bouncier feel.
- What It’s Made Of: Medium firm side has a responsive polyfoam layer, while the medium soft side has gel memory foam. Both sides share a pocketed coil core with reinforced edges, and a Tencel cover with water-repellent coating.
- What We Don’t Like: Not available in twin XL.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
While motion isolation may not be the biggest concern for sleeping kids, this mattress is somewhat responsive to movement. Children who share a bed may wake each other up with movements during the night.
Pressure Relief
Both sides of the Helix Kids alleviate pressure to a noticeable extent, but the softer surface gets the edge because it hugs the body more closely.
Temperature Control
The Helix Kids is fairly breathable thanks to steady airflow through its coil layer. While the foam layers can retain body heat, we don’t expect too many kids to feel uncomfortably warm on this mattress.
Edge Support
The Helix Kids offers decent edge perimeter due to the steel coils in its support core. The perimeter may not be extra strong, but chances are kids won’t be heavy enough to compress the edges excessively.
Ease of Movement
Kids shouldn’t have much trouble moving on the mattress. Foam layers can sink when weight is applied, but most children are light enough to move on foam without feeling stuck.
Durability
The Helix Kids mattress is a hybrid with a flippable design that should be suitable for kids through age 12. It uses memory foam on the softer side and polyfoam on the firmer side, as well as a pocketed innerspring support core. If it’s used by smaller children as intended, it should last them through grade school.
Best Value Mattress: Dreamfoam Hybrid
Best Value Mattress
7.6/10Test Lab Score
Dreamfoam Hybrid
Ultra-affordable hybrid with multiple firmness and thickness options.
Key Details
- Who It’s Best For: Side and back sleepers, especially those 130 to 230 pounds — children and adults.
- Feel: Medium firm (6). Quite squishy, offering a balance of contouring and spinal support.
- What It’s Made Of: Cover is quilted and has an integrated cooling panel made with phase change material. This is followed by 2.5 inches of gel memory foam, a 6-inch pocketed coil support core with reinforced sides, and a thin layer of base foam.
- What We Don’t Like
- May be too high for some bunks. May inhibit movement and allow too much sink for stomach sleepers. Return fee of $99.

In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Dreamfoam Hybrid performs surprisingly well when it comes to motion isolation, especially for a hybrid model at this price point. The gel-infused memory foam layer absorbs most movement before it can transfer across the surface, making this mattress a solid choice for couples or co-sleepers who are easily disturbed by motion at night.
Pressure Relief
The thick layer of memory foam delivers strong contouring and pressure relief, especially for side sleepers in the 130–230 pound range. The foam cradles common pressure points like the hips and shoulders, while the coils provide enough support to maintain healthy alignment for most back and stomach sleepers.
Temperature Control
Despite incorporating phase change material and gel-infused foam, the Dreamfoam Hybrid earns below-average marks for temperature regulation. The comfort layers tend to trap some heat, and although airflow through the coils helps to some extent, hot sleepers may find themselves seeking a cooler alternative.
Edge Support
While the Dreamfoam Hybrid doesn’t have reinforced edges, the perimeter still feels reasonably stable thanks to the support of the pocketed coils. Most sleepers should feel secure sitting or sleeping near the edge, but heavier individuals may notice more sinkage when getting in and out of bed.
Ease of Movement
The Dreamfoam Hybrid may feel slightly restrictive for combination sleepers or those who shift positions often. The memory foam creates a close “hug” around the body, which can make it harder to move freely or get out of bed quickly,particularly for those who prefer a bouncier surface.
Durability
Best Luxury Mattress: Saatva Youth
Best Luxury Mattress
8.4/10Test Lab Score
Saatva Youth
A reversible hybrid meant for growing children.
Key Details
- Who It’s Best For: Children and pre-teens.
- Feel: “Younger” side is firm (7) with sturdier spinal support to support development. The other side has more cushioning, with a medium (5) feel that may appeal more to older children.
- What It’s Made Of: Water-resistant organic cotton cover with a natural thistle flame barrier. Younger side is a polyfoam comfort layer with five zones, including a firmer section in the middle third. The softer side has a layer of convoluted polyfoam, backed by lumbar spinal wire. An innerspring core supports both sides.
- What We Don’t Like: Return fee of $99. Might be too thick for the lower bunk.

In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Saatva Youth feels fairly springy and responsive to movement, especially on the firmer side. Since motion isolation isn’t a major concern for most kids, this shouldn’t be an issue — and may even be a bonus for those who enjoy bouncy sleep surfaces. However, children who share a bed may wake each other up at night with position changes and trips to the bathroom.
Pressure Relief
The softer side of the Saatva Youth alleviates pressure by hugging the body and cradling sore spots. Sleepers may feel more pressure on the firmer side, which does not contour as closely.
Temperature Control
The Saatva Youth sleeps fairly cool thanks to breathable comfort system materials and steady air circulation through the support core. If your child sleeps hot, this mattress is a very safe bet.
Edge Support
The Saatva Youth’s perimeter is remarkably sturdy for a kid’s mattress. On top of the robust design, most kids won’t weigh enough to compress the edges on either surface of the mattress.
Ease of Movement
Both sides of the Saatva Youth are springy and responsive to movement, so kids should have an easy time moving on this mattress regardless of which surface they use.
Durability
The Saatva Youth should hold up at least seven to eight years, likely long enough for your child to grow out of it. Hybrid designs generally last longer than the average bed thanks to the durability of the coil support core, and the Saatva Youth uses particularly thick coils. The comfort layers on both sides use polyfoam, which is generally more durable than memory foam, though still tends to develop impressions and soft areas after enough use.
Most Comfortable Mattress: Bear Cub
Most Comfortable Mattress
7.7/10Test Lab Score
Bear Cub
A kid-friendly hybrid that’s firm and supportive.
Key Details
- Who It’s Best For: Teenagers, as well as kids aged 3 and up.
- Feel: Firm (7). Sleepers stay mostly on top of the bed and enjoy plenty of bounce from the coils.
- What It’s Made Of: Quilted Tencel cover, followed by a layer of gel memory foam, a layer of responsive polyfoam, and a 6-inch pocketed coil base.
- What We Don’t Like: Not at much pressure relief or “hug” as other mattresses.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Bear Cub is fairly firm and its coils add bounce, but the foam layers do a good job of muffling movement and preventing motion from transferring. Motion isolation is virtually a non-issue for children who sleep alone, but those who share a bed may feel some movement when their co-sleeper moves in bed.
Pressure Relief
The Bear Cub alleviates some pressure with its memory foam comfort layer, but the mattress may feel too firm for kids who enjoy a close hug from their mattress. On the flip side, a firmer mattress can help promote proper spinal alignment for children.
Temperature Control
Although the Bear Cub’s foam layers retain some heat, its support core promotes steady air circulation throughout the interior and the cover is made of breathable fabric. Hot sleepers should feel comfortable on this mattress.
Edge Support
The Bear Cub feels quite sturdy along its perimeter. This can be attributed to its firm feel and robust coil system.
Ease of Movement
Since the Bear Cub is firm and responsive to movement, most kids should be able to move across its surface easily and not feel “stuck” in the foam layers.
Durability
As it’s a hybrid mattress, the Bear Cub should hold up longer than the average bed, likely around seven to eight years. Hybrid models tend to be more durable, because their coil support cores maintain their performance better than all-foam counterparts. The Bear Cub’s polyfoam and memory foam comfort layer may develop impressions or sagging. However, since it’s designed for children who tend to weigh less, the foam may last a bit longer.
Best Mattress for Younger Kids: Nest Bedding Puffin
Best Mattress for Younger Kids
7.6/10Test Lab Score
Nest Bedding Puffin
A firm all-foam mattress built with kids in mind.
Key Details
- Who It’s Best For: Toddlers and young school-age children, as well as hot sleepers.
- Feel: Firm (7). Quick-response foam in the top layer prevents kids from feeling “stuck” in the bed.
- What It’s Made Of: Quilted cover lined with phase change material. Comfort system contains 2 inches of Energex polyfoam. Base is 5-inch polyfoam.
- What We Don’t Like: Weight limit is 110 pounds.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Nest Bedding Puffin isolates a decent amount of motion due to its all-foam design. That said, motion isolation won’t be a major concern for kids unless they share their bed with someone else.
Pressure Relief
The Puffin’s all-foam design offers decent pressure relief with a light, even contour on the surface with just enough hug to keep kids comfy. The firmer feel also helps ensure proper spinal alignment for young sleepers.
Temperature Control
The Puffin’s foam layers can absorb heat, but this shouldn’t be a major issue because the mattress is firm and doesn’t hug too closely. Cooling sheets may be helpful for kids who run extra warm in bed.
Edge Support
Edge support is fair. The Puffin’s firmer feel makes the surface feel stable, but the base foam may still sink along the perimeter when more than 50 pounds is applied.
Ease of Movement
The Puffin is firm, but also contains foam layers that can sink and make people feel “trapped” when they move on the surface. However, most kids won’t weigh enough to encounter much resistance on this mattress.
Durability
The low durability score for the Nest Bedding Puffin is mainly due to the fact it’s designed for children, and therefore has a thinner profile and less robust support core. Nest Bedding specifies a 110-pound weight limit for this all-foam bed. Children in this weight category exert less pressure on the mattress, and with its firm surface, the bed should still last quite a few years before needing to be replaced.
Best Low Profile Mattress: Dreamfoam Essential
Best Low Profile Mattress
7.2/10Test Lab Score
Dreamfoam Essential
A budget-friendly foam mattress with many firmness options.
Key Details
- Who It’s Best For: Adult side sleepers (10-inch model), as well as kids and adult back or side sleepers (6- or 8-inch model).
- Feel: Medium soft (4) to firm (8). The thinner models are firmer due to their thinner comfort systems.
- What It’s Made Of: A layer of gel-infused memory foam over a high-density polyfoam base. The 12- and 14-inch models have an additional layer of transitional polyfoam.
- What We Don’t Like: May trap heat. Difficult to change positions. Return fee of $99.

The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
Based on our tests, the 12-inch and 14-inch models of the Dreamfoam Essential Mattress perform best at motion isolation, while the 6-inch and 8-inch models may be too disruptive for sensitive sleepers who share the bed. The superior motion isolation of the thicker models is largely due to their thicker layer of memory foam, a material known for its ability to absorb movement, while the thin models lack the necessary cushioning to dampen movements.
Pressure Relief
With thick memory foam layers, the 12- and 14-inch Dreamfoam Essential beds provide above-average pressure relief. Plush cushioning in areas like the shoulders and hips is especially important for side sleepers.Most of our back and stomach sleepers sank too deeply into these models, but some found that the medium firm (6) 10-inch model struck a nice balance of cushioning and support.Due to their thinner profiles, the 6- and 8-inch models offer limited pressure relief.
Temperature Control
Traditional memory foam can retain heat and sleep hot. The Essential features breathable open-cell foams and gel infusions designed to limit heat buildup in the mattress.The 6- and 8-inch Dreamfoam Essentials sleep cooler than other memory foam models. These models are quite firm and don’t sink much, so air flows more easily around the skin. Hot sleepers may want to avoid the 10-inch, 12-inch, and 14-inch options, as our temperature tests show these mattresses can sleep warm.
Edge Support
Our testing team found that the thinner, firmer Dreamfoam Essential models provided a reliable base when getting in and out of bed. Testers were also able to lie close to the edge of the bed without feeling like they were going to roll off.By contrast, the thicker Dreamfoam Essential models allowed more compression around the perimeter. This led some of our testers to report feelings of instability, particularly for those who weigh more than 230 pounds.
Ease of Movement
Ease of movement describes how easy it is to switch sleeping positions. Foam mattresses don’t usually excel in this category because they offer little bounce and can feel clingy due to its close conforming. While the Essential doesn’t perform as well as a latex or hybrid mattress, we found it was modestly better than many other memory foam models. The memory foam layer is relatively thin, and the polyfoam layers below offer a firmness that prevented our testers from feeling trapped in the bed.
Durability
Durability is not one of the Dreamfoam Essential’s strong points. The firmer models are on the thinner side and may bottom out over time, whereas thicker models are softer and prone to surface-level indentations after a few years of use. While this mattress makes a great kid’s or guest room bed, it’s not really built to last and will probably need to be replaced within 5 years or so.
Best Organic Mattress: Avocado Eco Organic Kids Mattress
Best Organic Mattress
7.7/10Test Lab Score
Avocado Eco Organic Kids Mattress
A durable, supportive mattress for kiddos.
Key Details
- Who It’s Best For: Young back and side sleepers, as well as hot and combination sleepers.
- Feel: Firm (7). Latex provides resistance to prevent sleepers from sinking too far into the bed, while the coils below add pushback and a slight bounce.
- What It’s Made Of: Organic cotton cover lined with a moisture-wicking organic wool fire barrier. The body is 1 inch of Dunlop latex and a 6-inch pocketed coil core that’s made with recycled steel and encased in food-grade fabric.
- What We Don’t Like: Doesn’t offer plush pressure relief. Shipping take longer than usual. Return fee of $99.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Eco Organic doesn’t isolate motion very well due to its responsive latex and coil layers. That said, most kids won’t be bothered by this unless they share their bed with someone else.
Pressure Relief
Pressure relief is limited on this mattress due to the latex comfort layer, which provides some cushioning but doesn’t contour like foam. On the other hand, this mattress does a very good job of keeping the body on an even plane and promoting proper spinal alignment.
Temperature Control
The Eco Organic Kids sleeps very cool due to ventilated latex that promotes airflow near the surface and steady circulation through the coil layer. A breathable organic cotton cover also helps the mattress maintain a comfortable temperature.
Edge Support
Edge support is very sturdy for this mattress. Even adults should find the perimeter keeps them upright and doesn’t buckle too much beneath their weight.
Ease of Movement
This mattress is quite easy to move on because the latex and coil layers respond to movement with a strong bounce. Kids who enjoy springy beds should be happy with this model.
Durability
This mattress is exceptionally breathable, especially compared to other kid-friendly models. Latex resists wear and tear much better than foam, and the coils are thick and sturdy enough to provide years of robust support.
Best Mattress for Pressure Relief: Brentwood Home Juniper
Best Mattress for Pressure Relief

Brentwood Home Juniper
A cushy all-foam bed intended for little sleepers.
Key Details
- Who It’s Best For: Children who sleep primarily on their side or back.
- Feel: Medium firm (6). Cradles the sleeper to relieve pressure points without excessive sinkage.
- What It’s Made Of: One inch of gel memory foam over a 5-inch polyfoam base. Both foam layers contain a portion of plant-based materials, and the mattress is wrapped in a GOTS-certified organic cotton cover.
- What We Don’t Like: May sleep hot. Initial odor may linger.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Juniper isolates motion very well thanks to its all-foam design, which absorbs movement on the surface and prevents it from transferring elsewhere. However, motion isolation isn’t a major issue for kids who sleep alone.
Pressure Relief
Pressure relief is a major strength of the Brentwood Home Juniper, which conforms lightly and evenly to cradle children while they sleep.
Temperature Control
The Juniper uses breathable foam layers that resist heat buildup better than traditional memory foam. Kids may notice some warmth building up on the surface, but this shouldn’t be a major issue.
Edge Support
Edge support is limited, so kids may sink a bit when they get on and off the Juniper. If the mattress is placed on a top bunk, edge support is pretty much is a non-issue.
Ease of Movement
Some kids may struggle to move on the Juniper, but most are too light to compress the foam to a noticeable extent. Kids may have a harder time moving across the mattress as they grow older.
Durability
Durability is average for the Juniper. Like a lot of all-foam beds, this one may develop indentations and impressions in its surface within a few years of use.
How to Choose the Best Bunk Bed Mattress
In order to find the best mattress for a bunk bed, you’ll need to take a few factors into account. The mattress should meet certain size, weight, and thickness requirements for the bed, especially if you plan to use it on a top bunk. Other variables include price, durability, firmness level, and the age, body type, and sleep position of the sleeper who will primarily use the mattress.
Read on to learn more about choosing the best bunk bed mattress. We’ll also cover bunk bed styles and safety concerns for these bed models.
What to Look for in a Bunk Bed Mattress
During your search for the right bunk bed mattress, you’ll likely come across a wide variety of beds advertised with misleading terms and descriptions. Some mattress companies tout their models for “universal comfort” regardless of the sleeper’s body type and sleep position, or make the claim that their beds will last for at least 10 years. As you browse different brands and models, keep in mind that each mattress is designed to feel more comfortable for certain types of sleepers, and less so for others. We encourage you to focus on the nuts and bolts of the mattress and consider the following factors instead.
- Size: The vast majority of bunk beds sold today are compatible with twin, twin XL, and/or full mattress sizes. All three of these sizes are best suited to one person and will probably be too narrow for two or more sleepers. Make sure to check the specs on your bunk bed to see the proper size for each individual bunk.
- Profile: Low-profile mattresses of 6 to 7 inches thick are typically best for bunk beds. This ensures the mattress is thick enough to support the sleeper, but not too tall for the bunk and its safety rails. According to the U.S. Consumer Product Safety Commission, the mattress should be at least 5 inches shorter than the top of the rails. (Scroll down for a detailed list of bunk bed safety tips.)
- Weight: Bunk beds always have a listed weight capacity that includes all mattresses and sleepers. For this reason, lighter mattresses tend to be best for bunk beds. Excessively heavy mattresses pose serious safety concerns for sleepers on lower bunks. Before selecting a mattress, add up the total weight for all sleepers who will use the bed and subtract this number from the bed’s listed weight capacity.
- Contouring: Mattresses that contour evenly and consistently can distribute your weight and reduce pressure points throughout the body. Poor spinal alignment is a common issue for side sleepers, so they typically need closer contouring to ensure the shoulders, lower back, and hips are evenly supported.
- Noise: When picking out mattresses for a bunk bed, you should consider all-foam or all-latex models that do not make any noise. This can reduce nighttime disruptions for everyone sharing the bunk bed. Hybrids and innersprings tend to produce more squeaks and creaks due to their coil systems.
- Price: The cost of a new mattress largely depends on the bed’s material composition. All-foam and innerspring mattresses are the cheapest options, with an average queen size price-point of $900 to $1,200. All-latex and hybrid models cost a bit more – about $1,600 to $2,200 for a queen mattress, on average.
- Temperature Regulation: Mattresses with breathable components tend to sleep noticeably cooler than other models. These components may include ventilated latex or foam comfort layers, coil systems that promote steady air circulation, and covers made from breathable fabrics and fibers. All-foam mattresses generally absorb and trap the most body heat.
- Durability: The average mattress will perform for six to eight years before a replacement is needed. Excessive sagging and loss of support are the most common reasons for retiring a mattress. All-latex mattresses tend to last longer because latex is a naturally durable material that won’t sag or deteriorate as quickly as memory foam or polyfoam.
- Firmness Level: Mattress firmness is assigned using a 1-10 scale, with 1 being the softest and 10 the firmest. Most mattresses sold today fall between 3 and 8. A softer mattress conforms more closely for side sleepers and those weighing less than 130 pounds, but it will probably sink too much for people who weigh more than 230 pounds – especially back and stomach sleepers. These individuals should consider a firmer mattress with stronger support instead.
- Pressure Relief: For any given sleeper, the best mattress for pressure relief will conform to the body and support the spine without sagging too much beneath the sleeper’s heaviest areas. Therefore, a mattress that alleviates pressure very well for one sleeper may not provide enough relief for another person with a different body type or way of sleeping.
What Types of Bunk Beds Are Available?
If you’re in the market for a new bunk bed, you’ll be able to choose from a wide range of styles. The most common bunk bed designs include the following:
- Standard: A standard bunk bed is constructed with two stacked bunks of the same size. Most standard models are designed for two twin bunk bed mattress models, but you may also find some that are compatible with twin XL or full sizes instead. The top bunk is detachable, allowing you to separate the beds. This makes standard bunks ideal for two siblings who will eventually sleep in separate rooms.
- Triple: Triple bunk beds are built with three separate bunks of a matching size – twin, in most cases. The bunks may be stacked three-high. Another common design is two adjoining bunks on the bottom in a straight line or an L-shape, with the third bunk stacked over the middle where both bottom bunks intersect. Like standard bunk beds, most triple bunk beds can be detached to create three individual beds.
- Standard Loft: In a standard loft bunk bed, the sleep surface is stacked over an open space that measures at least three to four feet high. This space may contain a workstation with a desk and computer – a popular layout for college dorms and teenager bedrooms. Most standard lofts are also tall enough for a sofa or chair to fit underneath.
- Triple Loft: Triple loft bunk beds feature two top bunks that connect at a 90-degree angle. As is the case with a standard loft, you’ll find an open space of at least three to four feet high beneath one of the bunks. The other bunk is stacked over a third bed. Due to their larger specs, these bunk beds are normally positioned in one corner of a room to maximize floor space.
- L-Shaped Bunk: An L-shaped bunk bed features two individual bunks. Rather than being evenly stacked, the bunks are stacked in perpendicular fashion. A ladder next to the lower bunk allows sleepers to access the top bunk. Many L-shaped bunks also offer drawers or compartments for added storage.
- Twin-Over-Full: As the name suggests, a twin-over-full bunk bed is constructed with a twin size top bunk and a full size bottom bunk. These beds are a good option if you have three children sharing the bed but their room is not tall enough to accommodate a triple bunk.
- Trundle: A trundle bunk bed accommodates three individual sleepers. Two use the evenly stacked bunks, while a third bed can be accessed using a pull-out drawer attached to the bottom bunk. When not in use, the third bed can be pushed back in to free up more floor space.
- Futon: A futon bunk bed has a top bunk similar to that of a standard or triple bunk. The bottom contains a futon-style sofa that can be folded down to create a bed surface. Futon bunk beds are another popular choice for dorm rooms.
What Types of Mattresses Are Best for Bunk Beds?
Material composition is an important mattress consideration because each mattress type carries certain pros and cons based on its components. For bunk beds, all-foam models tend to work best. These mattresses are relatively light, so you won’t need to worry about exceeding the bunk bed’s weight capacity. They are also completely silent, allowing sleepers to get onto their bunk without disturbing their bunkmates.
Most mattresses sold today fall into one of five general categories based on their materials, but only a few of them are best for use in a bunk bed. Each category is fairly consistent across different models in terms of price, durability, and performance, but you’ll also find plenty of variation between models of the same type.
Foam
Definition: An all-foam mattress is constructed with comfort and transitional layers of memory foam or polyfoam. If a mattress contains both types of foam, it is considered a “mixed-foam” model. The support core is always made of high-density polyfoam. The average all-foam mattress costs between $900 and $1,200 in a queen size.
Exceptional Pressure Relief: Most all-foam mattresses offer noticeable body-conforming and even weight distribution. For side sleepers, softer all-foam models cushion the shoulders and hips to help align the spine and alleviate pressure. Firmer foam mattresses tend to alleviate more pressure for back and stomach sleepers by promoting even support with minimal sagging.
Hybrid
Definition: A hybrid is a specific type of coil mattress that offers more cushioning and closer body-conforming than a traditional innerspring. The comfort layers are often made from contouring materials like memory foam, latex, and microcoils, while the support core almost always contains pocketed coils and some type of base polyfoam. The average hybrid costs between $1,600 and $2,200 in a queen size.
Balanced Comfort and Support: Hybrids are a comfortable compromise for many sleepers. Their adaptive comfort layers offer a deeper contour, resulting in better pressure relief and motion isolation than you normally receive from a coil mattress. However, the coils offer sturdy edge support and better temperature control than the solid base layers found in all-foam and all-latex models.
Innerspring
Definition: An innerspring is usually constructed with one or two thin comfort layers of polyfoam, along with a support core of steel coils. Innersprings are the most popular type of mattress sold today. This category is also the cheapest, with the average queen size model priced between $900 and $1,100.
Excellent Responsiveness: Innersprings are highly responsive, creating a noticeable bounce on the surface than many people enjoy for sleeping (as well as sex). Most people have an easier time moving across these mattresses compared to those that respond more slowly and sink deeply. Edge support for innersprings is above average, as well.
Latex
Definition: Latex is a foamy material processed from the sappy extract of rubber trees. Latex is naturally responsive and feels bouncier than polyfoam or memory foam, but it also offers body-contouring and pressure relief without a deep sink. Latex is very durable, as well. The average latex mattress costs between $1,600 and $2,200 in a queen size.
Temperature Control: Latex does not absorb and trap heat like foam, so all-latex mattresses tend to sleep quite cool. Many of these models have ventilated layers for added airflow, and their covers are often made of breathable fabrics like organic cotton and rayon from bamboo.
Last Things to Consider with a Bunk Bed Mattress
Now that we’ve discussed bunk bed styles and the best types of mattresses for these beds, let’s conclude this guide with some final considerations for first-time bunk bed shoppers.
Bunk Bed Safety
Bunk beds are subject to federal laws outlined in the Consumer Product Safety Improvement Act of 2008 and other pieces of legislation. According to the U.S. Consumer Product Safety Commission (CPSC), federal bunk bed requirements include the following:
- Each upper bunk must have a guardrail on each side. Lower bunks do not require guardrails if they are 30 or fewer inches off of the ground.
- The guardrail must run the entire length of the side next to the wall. An exception is made for gaps of .22 inches or less between the guardrail and the nearest end.
- On the side away from the wall, gaps between the guardrail and the end of the bed cannot exceed 15 inches.
- The top of the guardrail must exceed the mattress profile by at least 5 inches on all sides.
The CPSC also lists requirements for bunk bed ends, entrapment prevention, and materials used to construct the bed. We encourage you to read all CPSC bunk bed requirements, and please make sure the bunk bed you buy meets all of the federally mandated criteria.
Long-Term Use
Mattress durability should be a major consideration, but you may not need a mattress with an exceptionally long lifespan for your bunk bed. Children often outgrow their mattresses during their pre-teen and teenage years. By the time they hit junior high or high school, they may be too tall for a twin or full size bunk bed mattress. In these cases, buying a cheaper mattress with a shorter lifespan for the bunk bed may be more cost-effective than paying top dollar for a very durable model.
Many siblings also stop sharing bedrooms when they reach these ages. Most bunks can be disassembled into single beds, allowing your child to keep using the same mattress after they no longer sleep in the bunk. If your child does not undergo any major growth spurts, they may be able to use the same mattress for the remainder of their childhood.
Body Weight
As we mentioned earlier, the listed weight capacity of a bunk bed refers to the sleepers and their mattresses. If your two children weigh 50 to 60 pounds and share a bunk bed with a 200-pound weight capacity, this means their mattresses should weigh no more than 40 to 50 pounds each. If the same children share a bunk bed with a weight capacity of 400 to 500 pounds, you’ll have more wiggle room for selecting a mattress based on weight.
Most bunk beds have weight capacities of 200 to 500 pounds. Always check this figure before buying mattresses for your bunk and never exceed the weight capacity under any circumstances.
How We Test: Your Comfort Is Our Science
Our industry-leading product testing team cares deeply about improving your sleep. Having a holistic understanding of a mattress’s role as part of a sleep system is paramount to our testing process. Since a bed’s comfort and feel depend largely on body weight and sleeping position, our testing team represents a wide range of body types, sleep positions, and comfort preferences.
In our Seattle-based Test Lab, we use an objective, hands-on process to evaluate mattresses across performance categories. The following are the key guidelines that inform our performance ratings. Our ultimate goal is to ensure you have all the information you need to make the best purchase decision for you.
Construction analysis: Mattress construction plays a major role in our ratings system. We begin our testing with a top-to-bottom analysis of each mattress, making note of its materials, firmness, thickness, and other physical attributes. Price-point is another major factor as we assess quality of materials and overall value.
Quantitative product testing: For hands-on testing, our team members take turns lying and moving on each mattress. This immersive process helps us evaluate beds for performance categories like motion isolation, pressure relief, ease of movement, and temperature control.
Field testing: Once we’re finished testing a mattress in our lab, one of our team members takes it home and sleeps on it in their own bedroom for two to three weeks. Field testing helps us understand how each mattress performs in the long term.
User feedback: In addition to our team’s testing data, we draw from customer surveys and product reviews to calculate our final ratings. This helps us ensure our findings are consistent with real-world experiences.
How We Determine Our Overall Scores
To determine a mattress’s overall score, we assign weighted percentages to performance categories based on how important they are to the individual sleep experience. For instance, areas like pressure relief and temperature control tend to matter more to people than something like off-gassing, and because more people sleep on their side and back than on their stomach, we weigh those positions more heavily
Performance Categories
Motion Isolation
This criteria alludes to the amount of motion a mattress absorbs when a sleeper moves on the surface. We use two testers lying side by side to evaluate motion isolation, who each feel for transfer while the other person moves on the mattress.
Temperature Control
To determine how well a mattress regulates temperature, we perform temperature tests and look closely at its materials and construction. Many mattresses are designed with cooling components meant to reduce heat retention.
Pressure Relief
A bed with strong pressure relief excels at preventing pressure from building up in areas like the shoulders and hips. Beds with even contouring and weight distribution are top performers when it comes to pressure relief.
Off-Gassing
A mattress in a box may release unpleasant chemical odors for a short period after you’ve unboxed it. The initial smell may be strong but typically fades within 2 or 3 days.
Ease of Movement
This criteria reflects how easily a sleeper can move across a bed’s surface. Responsive surfaces made of latex typically perform better than foam surfaces, which can inhibit movement.
Edge Support
We perform sit tests along a bed’s perimeter to measure how well the edges push back against weight. Mattresses with strong edge support have minimal sagging when sleepers sit on or lie close to the perimeter.
