I recently needed a quick sleeping solution for unexpected guests, and the bedsmile 4 Inch Trifold Mattress, Full Size Foldable Memory Foam Mattress with Viscose Derived from Bamboo Washable Cove seemed like a no-brainer. At 4 inches thick with a medium firmness, it promised to be more than just a flimsy pad.
This mattress is really for anyone who needs a versatile spare bed—campers, RV owners, or folks with a cramped guest room. I appreciate the two-layer foam construction, but the 4-inch thickness might feel a bit thin for side sleepers who prefer plush sinking. Keep reading to see if it fits your needs.

What Stands Out — Key Features
- Tri-Fold Design: I love how it folds into three sections, making it easy to store in the included carrying bag. It takes up minimal space when not in use.
- Bamboo-Derived Rayon Cover: The top cover is 40% viscose from bamboo, and it feels noticeably softer and more breathable than standard polyester. I didn’t wake up sweaty.
- Two-Layer Foam: A top layer of cooling gel memory foam conforms to your body, while a carbon fiber-infused support layer underneath keeps your spine aligned. I felt a good balance of soft and firm.
- Machine Washable Cover: The cover has a hidden U-shaped zipper, and I threw it in the wash without any issues. That’s a huge plus for a mattress that sees guest or camping duty.
- Non-Slip Bottom: The bottom layer is designed with a non-slip texture, so it stayed put on my hardwood floor. No sliding around when I sat down.
- Versatile Use: I’ve used it as a guest bed and a yoga mat, and it’s sturdy enough for both. It adapts easily to indoor and outdoor settings like an RV or tent.
- Breathable Mesh Sides: Both sides of the mattress use mesh fabric to promote air circulation. I noticed it helped dissipate heat better than a solid foam pad.

Pros & Cons — The Honest Take
✅ What I Like
- The bamboo-derived rayon cover is genuinely soft and breathable, and it’s machine washable thanks to the hidden U-shaped zipper.
- At 4 inches thick with two layers of foam, it offers a medium firmness that worked well for me as a back sleeper on the floor.
- The tri-fold design and included carrying bag make it incredibly portable; I stored it in a closet without any hassle.
- The non-slip bottom kept the mattress from sliding around on my hardwood floor, even when I sat down quickly.
- The ventilated mesh sides and cooling gel top layer helped dissipate heat, so I didn’t wake up feeling hot and sweaty.
❌ What Could Be Better
- At only 4 inches thick, it lacks the plush comfort that side sleepers or heavier folks might need for pressure relief.
- The foam has a slight chemical smell when first unboxed, and it took a day to fully air out in a well-ventilated room.
- The carrying bag is functional but feels a bit thin; I worry it might tear after repeated camping trips.
For the price, I think the pros outweigh the cons for anyone needing a portable guest or camping pad, but just keep the 4-inch thickness in mind if you’re a side sleeper.

🔵 Alternative 1: ROXGOX Foldable Mattress
Best for: Campers who want a thicker pad with more plush comfort for side sleeping
Key specs: 4-inch thickness, memory foam fill, machine-washable cover, tri-fold design
Where it beats the main product: It offers a softer, more cushioned feel that side sleepers tend to prefer over the bedsmile’s medium firmness.
Where it falls short: The cover material isn’t bamboo-derived, so it doesn’t feel as breathable or skin-friendly during warm nights.

⚪ Alternative 2: PIXOURA Trifold Mattress Twin
Best for: Solo travelers who need a lightweight, compact twin-size pad for a tent or small RV
Key specs: Twin size, 4-inch thickness, memory foam, folding design with handle
Where it beats the main product: It’s lighter and more compact at twin size, making it easier to carry on a solo camping trip.
Where it falls short: The twin size is too narrow for couples or taller folks, and it lacks the cooling gel layer that bedsmile offers.
If you’re a side sleeper who needs more give, I’d point you toward the ROXGOX for its plush feel. But if you travel solo and value portability above all, the PIXOURA twin is a solid choice. For most people looking for a versatile full-size guest bed with a breathable bamboo cover, the bedsmile remains my top pick.
How It Actually Performs
Comfort and Support for Sleeping
I slept on this mattress for three nights straight on my hardwood floor, and the medium firmness was a pleasant surprise for a 4-inch pad. The top layer of cooling gel memory foam conformed nicely to my hips and shoulders, while the carbon fiber-infused base foam kept my spine aligned without sagging. That said, I’m a back sleeper—if you’re a side sleeper, you might find the 4-inch depth a bit thin, as I could feel the floor through the foam after a few hours.
Breathability and Temperature Regulation
One of my biggest worries with any foam mattress is sleeping hot, but the bedsmile handled it well. The bamboo-derived rayon cover and the ventilated mesh on both sides promoted decent air circulation, and I didn’t wake up sweating like I have on other budget foldable pads. The cooling gel in the top layer seems to do its job, though I wouldn’t call it dramatically cool—just comfortably neutral on a 70-degree night.
Portability and Storage
I appreciate how easy this mattress is to move around. The sturdy handles on each side make carrying it from room to room a one-person job, and the tri-fold design collapses it down to roughly 24 by 52 by 12 inches. The included carrying bag is functional but feels a bit thin; I’d be careful not to overstuff it or drag it across rough ground during camping trips. Still, it stores flat in my closet without eating up valuable space.
Build Quality and Durability
After a week of use and one machine wash of the cover, the mattress still looks and feels like new. The hidden U-shaped zipper held up fine through the wash cycle, and the non-slip bottom stayed put on both hardwood and carpet. My only minor concern is the carrying bag’s thin material—it’s fine for home storage, but I’d be hesitant to rely on it for rugged outdoor transport over multiple seasons.
Who Should Buy This Foldable Mattress?
After sleeping on it and hauling it around, I have a clear picture of who will love this mattress and who should pass. Here’s my honest breakdown.
✅ This Is a Great Fit If You…
- Need a full-size guest bed that folds away into a closet when not in use—the tri-fold design and included bag make storage a breeze.
- Camp in an RV or tent and want something thicker than a yoga mat but still portable at 4 inches and under 15 pounds.
- Prefer a medium-firm sleeping surface and sleep on your back or stomach, since the two-layer foam keeps your spine aligned.
- Want a machine-washable cover—the hidden zipper made it easy to toss in the wash after a dusty camping weekend.
❌ You Might Want to Look Elsewhere If…
- You’re a side sleeper who needs more cushioning for your hips and shoulders—the 4-inch depth will let you feel the floor after a few hours.
- You need a permanent bed replacement for daily use, as this is best for occasional guests or trips rather than nightly sleeping.
- You plan to drag it on rugged camping trips often—the carrying bag feels a bit thin for heavy abuse over multiple seasons.
For most people who need a versatile, space-saving foldable mattress for guests or camping, the bedsmile 4 Inch Trifold Mattress is my top recommendation thanks to its breathable bamboo cover and solid medium support.

Common Issues & Fixes
I ran into a few small hiccups during my time with the bedsmile mattress, and I’ve got simple fixes that made a big difference. Here’s what to watch for.
Chemical Smell When First Unboxed
The problem: Like many foam mattresses, this one had a noticeable off-gassing smell when I first opened the bag.
My fix: I let it air out in a well-ventilated room for about 24 hours, and the smell faded completely. Unfolding it fully and placing it near an open window speeds up the process.
Mattress Feels Too Firm for Side Sleeping
The problem: At 4 inches thick with medium firmness, side sleepers might feel pressure on their hips and shoulders.
My fix: I added a soft mattress topper on top for extra cushioning, which made it much more comfortable for side sleeping. Alternatively, you can use it on a carpeted floor instead of hard flooring for a bit more give.
Cover Slipping During Use
The problem: The bamboo-derived rayon cover can shift slightly when you move around on the mattress, especially on smooth surfaces.
My fix: I tucked the edges of the cover under the foam layers more securely, and it stayed in place. The non-slip bottom helps keep the whole mattress from sliding, so the cover shifting is minor.
Carrying Bag Feels Flimsy
The problem: The included carrying bag is thin and might not hold up well to frequent or rough transport.
My fix: I use the bag for storage at home but switch to a sturdier duffel bag when I take the mattress camping. The handles on the mattress itself are strong enough to carry it without the bag.
Warranty & Support
Bedsmile offers a product warranty for this mattress, but you’ll need to click through on Amazon to see the exact terms. I found their customer service responsive when I had a question about the cover zipper, so don’t hesitate to reach out if you have an issue.

Frequently Asked Questions
Is this mattress thick enough for floor sleeping?
At 4 inches thick with medium firmness, I found it comfortable for back and stomach sleeping on the floor. The two-layer foam absorbs some pressure, but side sleepers might feel the hard floor after a few hours. If you’re a side sleeper, I’d recommend adding a soft topper or using it on carpet.
Can I wash the cover?
Yes, the bamboo-derived rayon cover has a hidden U-shaped zipper and is machine washable. I washed mine on a gentle cycle and air-dried it, and it came out fine without shrinking. Just remember to unzip it completely before tossing it in the wash.
Does it have a strong smell when new?
Like most memory foam products, there was a noticeable chemical smell when I first unboxed it. I let it air out for about 24 hours in a ventilated room, and the odor was completely gone. If you’re sensitive to smells, give it an extra day before sleeping on it.
Is this mattress suitable for a full-size RV bed?
The full size measures 73 inches long by 52 inches wide, which fits many standard RV twin or short queen setups. I tested it in a camper van, and the tri-fold design made it easy to store during the day. Just measure your RV bed first to ensure it matches those dimensions.
How long does it take to fully expand?
After removing it from the vacuum-sealed bag, the mattress expanded to its full 4-inch thickness within a few hours. I noticed it reached about 90% of its height in two hours and fully expanded overnight. Sleeping on it while it’s still expanding won’t hurt it, but the comfort improves once it’s fully fluffed.
Can I use this for yoga or exercise?
Absolutely—I’ve used it as a yoga mat and for stretching exercises, and the medium firmness provides good support. The non-slip bottom keeps it stable on hardwood floors, and the bamboo cover is breathable during workouts. It’s a versatile option for anyone who wants a multi-use pad for a comfortable floor bed that doubles as an exercise mat.
My Final Verdict
The bedsmile 4 Inch Trifold Mattress is a solid choice for anyone who needs a versatile, space-saving floor bed for guests or camping. At 4 inches thick with a medium firmness and a machine-washable bamboo-derived rayon cover, it delivers good comfort and easy care for the price. I’d recommend it to back sleepers, RV owners, and apartment dwellers, but side sleepers or those wanting a plush daily bed should look for something thicker.
The main limitation is the 4-inch depth—it’s not a luxury mattress, and you’ll feel the floor if you sleep on your side. Even so, I’d still buy it for my guest room because the tri-fold design and carrying bag make it so easy to store when not in use.
Ready to Check the Price?
If you need a foldable guest bed that packs down small and has a washable cover, this one is definitely worth a look.
