#1. Bear Trundle
Pros:
- Made with CertiPUR-Us certified foam
- Cooling
- Pressure relieving
- Lifetime warranty
Cons:
- May not be suitable for heavier-set sleepers
- Slight off-gassing
Our experience with Bear Trundle:
Made especially for trundle beds, the Bear Trundle mattress features the same quality materials as their regular mattresses, such as their Celliant covers and cooling-gel-infused memory foams.
Celliant has long been touted as a miracle textile when blended into items such as clothing, bedding, and yes, mattress covers. It can aid with rest and recovery by converting body heat into infrared energy.
The Bear Trundle mattress comes encased in a mattress cover that's made up of a Celliant blend that's both breathable and moisture-wicking, making it a good trundle mattress choice for those who tend to sleep hot.
When it comes to firmness levels, the Bear Trundle mattress has a medium feel suitable for all sleeper types, from side sleepers to stomach and back sleepers.
There are two foam layers in the Bear Trundle mattress. The primary comfort layer is made up of cooling gel-infused memory foam that offers the same contouring and pressure-relieving properties as true memory foam but without any of the dreaded heat retention. The base layer acts as the support layer, made up of high-density support foam that gives the mattress its stability and durability.
All the foam layers in the Bear Trundle mattress are CertiPUR-US certified and free from harmful chemicals and VOCs, which means your little ones can sleep safe and sound.
Sizes:
- Twin
Financing: Bear offers financing for all their mattresses through Affirm.
Shipping, Trial Period and Warranty: Bear offers a 120-night risk-free trial period for all their mattresses. The Bear Trundle mattress comes backed by a lifetime warranty. Bear also offers free shipping for all their mattresses within the United States.
#2. Saatva Bunk and Trundle Mattress
Pros:
- Offers zoned lumbar support
- Cover is treated with botanical-based antimicrobial treatment
- Suitable for heavier-set sleepers
- Can be used in both bunk beds and trundle beds
Cons:
- May be too pricey for some
- Low profile may limit mobility for more mature adults
Our experience with Saatva Bunk and Trundle Mattress:
Not many trundle mattresses come as a hybrid mattress, but the Saatva Bunk and Trundle mattress combines the benefits of both an innerspring mattress and a memory foam mattress.
You might be thinking, is it really possible that I wouldn't feel the steel coils within such a thin mattress? And the answer is no, you definitely won't.
The Saatva Bunk and Trundle mattress contain an eco-insulator pad (in addition to a transition layer) that prevents you from feeling the coils through the mattress.
The mattress has several layers that serve a purpose. First, there's the cooling gel-infused memory foam lumbar crown layer that offers targeted support for the lumbar area. The transition layer, which also acts as a comfort layer, is made up of polyfoam that offers added support and pressure relief.
Below that lies the eco-insulator pad for extra security against any pokey things. The coil unit is made up of 4" recycled steel coils encased in foam for even more responsive support. The base layer is high-density foam that holds all the upper layers together for stability.
The mattress cover is made from GOTS certified organic cotton that's breathable and moisture-wicking. PlushBeds uses a plant-based fire barrier, so you can be sure that your mattress is completely fiberglass-free.
You get 2 medium firmness options to choose from: a Medium and a Medium-Firm. A medium mattress suits all sleeper types, while a medium-firm mattress would work best for those who sleep mainly on their backs and/or stomachs.
The Saatva Bunk and Trundle mattress comes in three standard mattress sizes and measures 6" in thickness. It works well with either a bunk bed or a trundle bed.
Financing: Saatva offers financing for all their mattresses through Affirm.
Shipping, Trial Period and Delivery: Saatva offers a 365-night sleep trial for all their mattresses. The Bunk and Trundle mattress comes backed by a lifetime warranty. Saatva offers free in-room delivery and setup within the United States.
#3. 5 Little Monkeys Original Memory Foam Mattress
Pros:
- Thicker than most trundle mattresses
- True memory foam feel
- Pressure relieving and body contouring
Cons:
- Slight off-gassing
- May be a bit too firm for some
Our experience with 5 Little Monkeys Original Memory Foam Mattress:
Don't be fooled by the seemingly made-for-kids brand name, the 5 Little Monkeys Original Memory Foam mattress can accommodate a full-sized adult comfortably.
Thicker than most mattresses typically used in trundle beds, the 5 Little Monkeys Original Memory Foam mattress can not only be used as a trundle bed but also as a guest bed.
Formulated specifically for children, the Original Memory Foam mattress contains premium quality memory foam that's CertiPUR-US certified, meaning it's free from all the nasties, which is crucial, especially if the mattress will be used by kids.
Leaning towards the firmer side on the firmness level spectrum, the 5 Little Monkeys Original Memory Foam mattress is suitable for growing kids as well as adults who are generally back and stomach sleepers.
The mattress contains a blend of different premium foam types that provide comfort, pressure relief, and proper spinal alignment - important for growing bodies.
The primary comfort layer is made up of high-density plush memory foam that offers that deep pressure relief and body contouring that true memory foam is known for. Right below that is a layer of high-resiliency medium Energex foam that counteracts the sinkage that comes with memory foam.
The base and support layer make up the bulk of the mattress, giving it its firmness. It is made up of high-density foam that provides stability and extra support.
We experienced a tiny bit of off-gassing when we first unboxed the 5 Monkeys Original Memory Foam mattress, but this dissipated within 48 hours.
The mattress comes in three standard sizes and measures 8" in thickness.
Financing: 5 Monkeys offer financing for all their mattresses through ShopPay.
Shipping, Trial Period and Warranty: All 5 Monkeys mattresses come with a 100-night risk-free sleep trial. The Original Memory Foam mattress comes backed by a 15-year limited warranty. Shipping is not free.

- Suitable for all sleeper types
- Fiberglass-free
Cons:
- Expensive (for a trundle bed)
- May not be suitable for heavier-set sleepers
Our experience with PlushBeds Natural Bliss:
The PlushBeds Natural Bliss mattress is not necessarily a trundle mattress per se, but it's possibly one of the best vegan mattresses to be had.
With certifications from Greenguard Gold, GOTS, USDA Organic, eco-INSTITUT, Control Union, and the Forest Stewardship Council, the Natural Bliss comes backed by all the big kahunas and with good reason.
Made with a blend of Talalay and Arpico latex - the most premium types of latex available - the PlushBeds Natural Bliss mattress contains nothing synthetic or chemical-based whatsoever.
The first comfort layer is made up of all-natural Talalay latex, which offers pressure relief just like true memory foam does but with more bounce and none of the sinkage.
The base and core layer are made up of denser and firmer GOLS certified Arpico latex, providing support and proper spinal alignment.
Both latex layers are naturally cooling and hypoallergenic, making it a great option for hot sleepers.
The mattress cover is made from GOTS certified organic cotton that's breathable and moisture-wicking. PlushBeds uses a plant-based fire barrier, so you can be sure that your mattress is completely fiberglass-free.

- Water-resistant cover
- CertiPUR and Greengold certified
- Fiberglass-free
Cons:
- Not suitable for heavier-set adults

Our experience with Helix Kids:
Want a mattress just for the kids? The Helix Kids mattress is your best bet.
A hybrid mattress that's flippable and designed for growing bodies, the Helix Kids mattress provides comfort, support, and durability that can accommodate children from ages 3 to 12.
Younger kids need something firmer to mold growing bones, while children aged 8-12 may need something softer since their pressure points would be more pronounced at this stage.
The Helix Kids mattress has all of that. It features a flippable design, with one side firmer and the other side softer.
The mattress contains Helix's own responsive foam as the primary comfort layer, giving it a firmer, more supportive feel for children aged 3-7. The coil unit is made up of individually pocketed spring coils for even more support and proper spinal alignment. The coil unit also features reinforced sides for active kids who tend to move around a lot while they sleep.
Below the coil unit, there's a gel memory foam layer that's softer and more contouring, giving the bed a plusher, more pressure-relieving feel. Each side of the mattress features a fiberglass-free fire barrier for extra protection.
All these layers come encased in a cool-to-the-touch, hypoallergenic cotton mattress cover that's water-repellent and removable for easy cleaning.
The Helix Kids mattress is certified by both CertiPUR-US and Greenguard Gold.
The mattress comes in two sizes and measures 8" in thickness.
Financing: Helix provides financing for all their mattresses via Affirm.
Shipping, Trial Period and Warranty: Helix provides a 100-night sleep trial for all their mattresses. The Helix Kids mattress comes with a 10-year limited warranty. Shipping is not free for the Helix Kids mattress.

How to Choose a Trundle Bed Mattress
There are a few key things to consider before choosing a trundle mattress.
Size
Check your trundle bed measurements. This is the first thing you must do before even considering buying a mattress. Choosing the wrong size will result in unnecessary headaches.
Body Weight
The heavier the sleeper, the more support they need. A hybrid mattress or an innerspring mattress provides more support for heavier-set sleepers, as opposed to an all-foam mattress. Choose accordingly.
Material
This depends on personal preferences. Most people tend to sleep hot, so choose a mattress that has active cooling properties. Latex mattresses are cooling, hypoallergenic, and more responsive than regular foam mattresses. Innerspring mattresses offer maximum support and responsiveness. Hybrid mattresses are a blend of foam and coils, providing the benefits of both.
Budget
Choose something that suits your budget and lifestyle. Mattresses used in trundle beds can vary in price depending on materials, type, and brand.
Frequency of Use
Will the mattress be used daily or just occasionally? Mattresses used regularly need to be durable and stable, while occasional use mattresses can have a bit more leeway.
Types of Mattresses You Can Use with a Trundle Bed
Just like regular beds, you can use any type of mattress in a trundle bed as long as it fits. Here are the most common types:
- Memory foam: Offering pressure relief and body contouring, memory foam mattresses are a popular choice for trundle beds.
- Latex: Cooling, hypoallergenic, and responsive, latex mattresses are ideal for those with allergies.
- Innerspring: Best for those who need more support, innerspring mattresses offer maximum support and responsiveness.
- Hybrid: A blend of foam and coils, hybrid mattresses provide a balance of comfort and support.
How Thick Should a Trundle Mattress Be?
Trundle mattresses should be low profile. Anywhere from 5-8 inches will fit most standard trundle beds. Customized trundle beds can accommodate thicker mattresses if desired.
What is a Trundle Bed?
A trundle bed is a type of bed that is essentially two beds in one. It can come as a roll-out bed or a pop-up trundle.
Roll-out trundle beds usually have wheels or casters on their bottoms, while pop-up trundle beds have a spring mechanism that allows them to pop in and out. Trundle beds are ideal for those short on space, needing an additional bed for guests, or for families with children. They provide a convenient way to save space when extra room is not available.
Conclusion
The best trundle mattresses provide the same pressure relief and support as regular mattresses, ensuring better sleep quality for both children and guests. They come in a wide range of sizes and mattress types to suit your needs, preferences, and budget. Our top choice is the Bear Trundle Mattress. It offers cooling, pressure relief, and comes with a lifetime warranty. Save 25% on your order with coupon code SLEEPLINE25.
