If you have scrolled through TikTok or Instagram lately, you have likely seen the “floor living” aesthetic: cozy, minimalist bedrooms with no bed frames, just plush mattresses on tatami mats. Or maybe you are just tired of inflating air mattresses for guests only to have them wake up on the floor by 3 AM.
Enter the Zonli 4-Inch Memory Foam Floor Mattress. Zonli is primarily famous for their cooling blankets, but they have quietly entered the floor mattress game to compete with heavyweights like MAXYOYO. It promises the support of a real bed with the portability of a sleeping bag. But is 4 inches really enough to keep your hip bones off the hardwood?
My Experience With The Zonli Floor Mattress
I purchased the Queen Size, 4-Inch “Upgraded” model (Wheat color).
I intended to use it as a guest bed, but for the sake of this review, I slept on it for a week straight on a hardwood floor.
Unboxing: It arrives vacuum-sealed in a surprisingly small box. Once you cut the plastic, it hisses and starts to expand.
Warning: It smells. There is a distinct “new car/chemical” scent (off-gassing) common with memory foam.
I had to unzip the cover and let it air out in a spare room with the window open for a full 48 hours before the smell faded and the foam reached its full 4-inch height.
The Sleep Test: The mattress is constructed with a layer of memory foam sandwiched between plush fiber filling. The result is unique—it feels firmer than an air mattress but softer than a traditional Japanese cotton futon.
- Back Sleeping: Fantastic. The memory foam fills the arch of your back, and you feel grounded and stable.
- Side Sleeping: Surprisingly okay. My hips didn’t hit the floor, but after 6 hours, I did feel a little pressure on my shoulder. If you are a heavy side sleeper (over 200 lbs), 4 inches might be pushing the limit.
The “Cooling” Factor: Since Zonli is a cooling brand, the cover is made of 100% cotton and feels breathable. I didn’t wake up sweaty, which is a common problem with all-foam floor mats. It doesn’t feel “cold” like an ice pack, but it doesn’t trap heat like a polyester sleeping bag.
Storage: Rolling this thing up is a workout. It comes with two straps and a storage bag, but wrestling a Queen-sized foam slab into a burrito shape requires some elbow grease. It is not tiny when packed; imagine a very large, heavy yoga mat. It takes up a good chunk of closet space.

Pros Of The Zonli Floor Mattress
- Superior to Air Mattresses: This is the main selling point. It will never pop, it will never leak, and it doesn’t make that squeaky rubber noise when you roll over. Your guests will actually sleep through the night.
- Removable, Washable Cover: Unlike many traditional futons where you are stuck with the fabric forever, the Zonli 4-inch model has a zipper. You can take the cover off and machine wash it. If you have kids or pets, this is a non-negotiable feature.
- Hybrid Foam/Fiber Feel: Pure memory foam can be too sinking; pure cotton batting can be too hard (like sleeping on a gym mat). Zonli hits a “Goldilocks” zone—the foam provides support, while the fiber top adds that “cloud” pillow-top feel.
- Non-Slip Bottom: The underside has little silicone grip dots. This sounds minor, but it prevents the mattress from surfing across the room if you toss and turn on a hardwood floor.
- Versatility: I found myself dragging it into the living room for movie nights. It turns any floor space into a lounge. It’s also excellent for car camping if you have an SUV or truck bed.
Cons Of The Zonli Floor Mattress
- Bulky Storage: Do not underestimate the size. Even when rolled up and strapped, a Queen size is roughly the size of a large checked suitcase. If you live in a tiny studio with zero closet space, this will be an obstacle in the corner of your room.
- The “Egg Crate” Texture: One side of the internal foam is flat, and the other is an “egg crate” (convoluted) texture. Some users find the egg crate side feels lumpy. You can flip the internal foam, but you have to unzip the whole thing to check which side is up.
- Off-Gassing Odor: As mentioned, you cannot use this the night you buy it. You must plan for a 24-48 hour airing-out period. If guests are arriving in 2 hours, this won’t work.
- Not for Heavy Side Sleepers: If you are over 200-220 lbs and sleep strictly on your side, you might “bottom out” (compress the foam until you feel the hard floor). Back sleepers or lighter side sleepers won’t have this issue.
Maintenance & Setup Tips
- The “Walking” Trick: To help it expand faster after unboxing, walk gently all over the mattress in your socks. This helps break the vacuum seal in the foam pores and encourages it to fluff up.
- Sheet Hack: While the cover is washable, it’s a pain to take off and put back on. I recommend using a standard fitted sheet over it. A standard Queen fitted sheet will be loose (since the mattress is only 4 inches thick), but you can use “sheet suspenders” to clip it tight underneath.
- Rotate It: If you sleep on it nightly, rotate it head-to-toe every two weeks. Floor mattresses are prone to developing body impressions faster than thick coil mattresses.
- Sun It: Like traditional Japanese futons, putting this in direct sunlight for an hour once a month helps kill bacteria and refreshes the loft of the fiber filling.
Comparison with Competitors
- Zonli vs. MAXYOYO: MAXYOYO is the most popular brand on Amazon. Zonli generally has a better cover. MAXYOYO often uses microfiber (polyester) which can sleep hot. Zonli uses cotton, which breathes better. However, MAXYOYO offers way more fun patterns and colors. If you care about sweat, pick Zonli. If you care about aesthetics, pick MAXYOYO.
- Zonli vs. Traditional Shikibuton (J-Life): A real Japanese Shikibuton is 100% cotton with no foam. They are much harder and require daily folding. Zonli is softer and more “Western.” If you want the authentic, firm experience, get a J-Life. If you want comfort and familiarity, get the Zonli.
- Zonli vs. Air Mattress: There is no competition. An air mattress is a temporary emergency solution. The Zonli is a legitimate piece of furniture. It costs about $40 more than a high-end air mattress, but it lasts for years.

Frequently Asked Questions (FAQ)
Yes. Many people use this as their permanent bed (often paired with a Tatami mat underneath for airflow). It is supportive enough for daily use, provided you are okay with a firm surface.
If you live in a humid climate, yes. Placing any mattress directly on the floor can trap moisture and cause mold. A Tatami mat or slat roll allows air to circulate under the mattress. If you are just using it for guests for 2-3 nights, the floor is fine.
The standard “Floor Mattress” is not waterproof. However, Zonli sells a specific “Camping” version that is water-resistant. If you are buying the soft cotton version for indoor use, use a waterproof protector if you have pets.
Unzip it, remove the foam core (this is a two-person job usually), and wash the cover on a gentle cycle with cold water. Air dry the cover; putting it in a hot dryer might shrink the cotton, making it impossible to get back on the foam.
Conclusion
The Zonli Floor Mattress is the “Air Mattress Killer.” It bridges the gap between a college sleeping bag and a real bed. While it requires storage space and a break-in period for the smell, the sleep quality is undeniably better than any inflatable option. It is perfect for minimalist living, frequent movers, or anyone who wants their guests to actually like them.
