At The Beloit Mattress Company, we handcraft each trundle mattress to fit perfectly under daybeds, bunk beds, and guest beds while providing real comfort that lasts.
Trundle Mattresses – Handcrafted Comfort for Small Spaces
We’re a fifth-generation, family-owned mattress manufacturer proudly building every mattress right here in our Wisconsin factory. Since 1929, we’ve handcrafted premium, factory-direct mattresses one at a time, never mass-produced.

Whether you’re outfitting a twin trundle for your child’s room, adding a hidden guest bed, or creating a cozy sleep space in a small apartment, choosing the right handcrafted trundle mattress makes every inch of your home more functional and inviting.

Gel Memory Foam
Our cooling gel memory foam trundle mattresses use CertiPUR-US® certified foams for healthier sleep and lasting performance. Multiple foam layers contour to the body, reducing motion transfer and providing deep pressure relief. Advanced cooling gel and breathable cotton covers help regulate temperature, keeping you comfortable all night. This option is especially beneficial for side sleepers and stomach sleepers who want a cooler, more adaptive mattress feel.
Ideal for: Guest rooms or kids’ trundles where cooler sleep and gentle pressure relief matter; great for side and stomach sleepers.
Natural Latex
Crafted with premium natural latex, our latex trundle mattresses are buoyant, breathable, and eco-friendly. Latex adapts naturally to all sleeping positions, making it an excellent choice for your main bed or guest rooms. The open-cell design improves airflow, while cotton and wool layers add softness, comfort, and temperature regulation. With natural latex, you get exceptional pain relief, durability, and a mattress built with safe materials that support better sleep quality.
Ideal for: Guest beds used frequently or nightly; ideal for allergy-sensitive sleepers and anyone wanting breathable, eco-friendly comfort.
Innerspring
Our innerspring mattresses for trundles use the Luxcore Spring Unit System, made with American 100% recycled steel wire. This design sleeps cooler than many foam builds, lasts longer, and provides targeted zoning for ideal firmness and support. The Vigor Edge Zoned Steel Perimeter gives strong edge stability, reduces roll-off, and ensures a consistent sleep experience. A great option for back sleepers and who want a traditional, responsive yet firm mattress feel.
Ideal for: Occasional guests, teens, or anyone who prefers a traditional, firmer mattress with durable edge support and cool airflow.
Hybrid
Our Hybrid trundle mattresses combine premium coil systems with plush foam layers or natural latex to create a balanced medium-firm profile. The coil support layer adds resilience and breathability, while the comfort layer provides adaptive contouring with either cooling gel foam or latex. This design offers superior pressure relief, reduced back pain, and versatility for multiple sleep positions. It’s a good choice for households needing a mattress that works for both kids and adults, whether for everyday use or occasional guests.
Ideal for: Versatile guest spaces needing universal comfort, combines coil support and plush foam or latex layers for all sleep positions.
Trundle Beds vs Sofa Beds vs Bunk Beds
When space is limited, choosing the right sleep setup matters.
- A trundle bed offers a hidden, pull-out sleeping space that saves floor space — perfect for kids’ rooms, guest areas, and small spaces.
- A sofa bed can work in a pinch, but most rely on thin fold-out cushions and metal bars that reduce comfort and long-term support. In contrast, a trundle bed paired with a handcrafted mattress delivers a real, supportive sleep experience every night.
- A bunk bed maximizes vertical space but can be harder to access, especially for adults or guests. A custom trundle mattress provides the same variety of sizes and sleeping capacity — without the ladders or bulky frames.
Here’s a quick look at how trundle beds compare to sofa beds and bunk beds at a glance:
| Feature | Trundle Beds | Sofa Beds | Bunk Beds |
|---|---|---|---|
| Sleeping Space | Hidden pull-out mattress that saves floor space | Fold-out cushions with bars and gaps underneath | Stacked beds maximize vertical space |
| Comfort & Sleep Quality | True handcrafted trundle bed mattress with customizable firmness and support | Thin, foldable cushions that reduce support and overall sleep quality | Varies by mattress type, but often limited in thickness |
| Best Use Cases | Guest rooms, kids’ rooms, and small spaces where flexibility is key | Occasional seating-to-bed conversion in living spaces | Permanent setups for kids or shared rooms |
| Accessibility | Easy pull-out design, low to the ground, safe for kids and adults | Simple fold-out but often heavy to set up | Top bunk is harder to access, especially for adults |
| Variety of Sizes | Available in twin trundle, full mattress, and custom builds | Usually full or queen, less flexible for custom mattress size | Mostly twin or twin XL, limited sizing options |
| Everyday Use | Excellent option with the right mattress build for nightly sleep | Not recommended for daily use due to poor support | Practical for kids, less ideal for adults long-term |

Trundle Mattress FAQs
Have questions about a trundle mattresses? Count on us to help you in any way we can.
What kind of mattress goes in a trundle bed?
Most trundle beds are designed for twin trundle mattresses, though some frames can fit a full mattress.
Is a trundle mattress the same as a twin?
A twin mattress is the most common size used in trundle beds, but not every trundle setup is identical. Some frames require slimmer builds or unique dimensions to slide properly under the main bed. We can handcraft your mattress to the exact mattress size and thickness your trundle bed frame requires.
Do trundle beds require special mattresses?
Not always, but they do require mattresses that fit the frame’s clearance. Many standard mattresses are too tall for a bottom trundle, so a thinner profile is usually best. Our team builds custom trundle mattresses with the right thickness so your bed opens and closes smoothly.
What are the disadvantages of a trundle bed?
The main limitation is clearance. Because trundle beds sit low to the ground, they sometimes need slimmer mattresses than traditional beds. Some models also require lifting or pulling out the bottom trundle, which may be less convenient for daily use. However, with a properly sized mattress and a quality build, a trundle bed is an excellent solution for small spaces and guest rooms.
How thick should a trundle mattress be?
Most trundle beds fit mattresses between 5 and 9 inches thick. This keeps the mattress low enough to slide under the main bed. We can adjust thickness based on your exact trundle bed setup, ensuring the perfect balance of comfort and functionality.
Can an adult sleep in a trundle bed?
Yes. With the right design, a trundle can comfortably support both kids and adults. We often recommend high-density foam or hybrid builds for adults who plan to use the bed for everyday use, since these materials offer long-lasting support and durability.
