I’ve spent time testing two of the most popular 4-inch tri-fold mattresses on the market: the Milliard Full Tri Folding Mattress and the MLILY Tri-Fold Memory Foam Topper. Both promise a portable, comfortable sleeping solution, but they serve slightly different needs based on their build and specs.
This comparison is for anyone who needs a temporary bed for camping, guests, or small apartments. The key trade-off here is between a dedicated mattress with a bamboo cover and a memory foam topper designed for temperature regulation. Keep reading to see which one I’d pick for my next trip.

Individual Product Breakdown
I put both of these tri-fold mattresses through the wringer by checking their build quality, comfort features, and real-world portability. Here’s what I found after sleeping on each one.
Milliard Full Tri Folding Mattress with Washable Cover
Full Size (75″ x 52″ x 4″) | Firm | 19,043 Reviews | 4.6 Stars
No products found.
This Milliard is the most popular tri-fold mattress on Amazon for good reason — it’s a dedicated sleeping pad, not a topper. I love that the removable bamboo cover is machine washable, which makes cleaning after a camping trip dead simple. The firm feel gives you solid support on the ground or a floor, and it folds up into a compact shape for storage. My only gripe is that it can’t be shipped to every location, so double-check your address before ordering.
✅ Pros
- Machine-washable bamboo cover keeps it fresh and clean
- Rated as firm, so you won’t bottom out on the floor
- Over 19,000 reviews with a 4.6-star average — people love it
- Folds into a compact, portable shape for travel or storage
❌ Cons
- Cannot be shipped to certain locations, so check availability
- No cooling gel layer, so it can sleep warm for some people
MLILY Tri-Fold Memory Foam Topper
Queen Size (80″ x 60″ x 4″) | 1.5″ Gel Memory Foam | 2,344 Reviews | 4.4 Stars
- Tri-fold Memory Foam Mattress topper: Our tri-fold memory foam mattress topper...
- Applicable to a Variety of Situations: Plus, the tri-fold mattress can be folded...
- Premium Structure: The foldable mattress topper consist of 1.5" Gel AeroFusion...
The MLILY is technically a mattress topper, but it works great as a standalone camping or guest bed. What sets it apart is the 1.5-inch layer of Gel AeroFusion Memory Foam on top of a 2.5-inch support base, which helps regulate temperature while you sleep. I also appreciate that it’s CertiPUR-US certified, meaning it’s free from harsh chemicals. The downside is that it’s a bit heavier than the Milliard and the cover isn’t made of bamboo, so it doesn’t feel as premium out of the box.
✅ Pros
- 1.5″ cooling gel memory foam layer helps with heat buildup
- CertiPUR-US certified for peace of mind on material safety
- Amazon’s Choice with over 600 bought in the past month
- Folds in seconds and stores easily in a cabinet or closet
❌ Cons
- Cover is not bamboo, so it feels less premium than the Milliard
- Weighs 11.29 kg (about 25 lbs), so it’s a bit heavy to carry long distances
Which One Should You Buy?
I know choosing between two solid 4-inch tri-fold mattresses can feel tricky, but the right pick really comes down to what matters most to you — cooling tech or a dedicated mattress build. Here’s my honest breakdown of who each one is for.
Milliard Full Tri Folding Mattress is right for you if…
- You want a dedicated camping mattress with a firm feel that won’t sag on the ground.
- You need a machine-washable bamboo cover for easy cleanup after outdoor trips.
- You prefer a product with a massive track record — over 19,000 reviews and a 4.6-star average.
MLILY Tri-Fold Memory Foam Topper is right for you if…
- You sleep hot and want the cooling benefit of a 1.5-inch Gel AeroFusion Memory Foam layer.
- You want a CertiPUR-US certified foam that you know is free from harsh chemicals.
- You need the larger Queen size (80″ x 60″) for more room to stretch out.
❌ Who Should Skip All of These?
If you need a mattress for permanent, nightly use in a bedroom, skip both of these. They’re 4 inches thick, which is great for temporary setups, but you’ll want a standard 8-to-12-inch mattress for long-term comfort and support.
For my money, the Milliard is the better choice for most campers and hosts. It’s a proven, dedicated mattress with a washable bamboo cover and a firm feel that keeps you off the floor — and with over 19,000 reviews backing it up, I trust it more for the long haul.
Frequently Asked Questions
Which is better for camping: the Milliard or the MLILY?
I’d pick the Milliard for camping. It’s a dedicated mattress with a firm feel that keeps you off the ground, and the machine-washable bamboo cover is perfect for cleaning up after a dusty trip. The MLILY is more of a topper, so while it works in a tent, the Milliard is built specifically for this purpose.
Is the MLILY worth more than the Milliard?
That depends on your priority. The MLILY has a 1.5-inch gel memory foam layer that cools you down, which the Milliard doesn’t offer. If you sleep hot, the MLILY is worth the extra consideration, but the Milliard is a better value for most people since it’s a dedicated mattress with a higher customer rating of 4.6 stars from over 19,000 reviews.
Which one is more comfortable for side sleepers?
I think the MLILY is better for side sleepers because of its 1.5-inch Gel AeroFusion Memory Foam layer, which contours to your hips and shoulders more than the Milliard’s firmer foam. The Milliard is rated as “firm,” so it’s better for back or stomach sleepers who need more support.
Can I use these mattresses on a bed frame or only on the floor?
Both can go on a bed frame, but they work best on a flat surface like the floor or a platform bed. The Milliard is 4 inches thick and firm, so it won’t sag on a slatted frame. The MLILY is designed as a topper, so it’s actually perfect for placing on top of an existing mattress to add comfort.
Which one is easier to clean and maintain?
The Milliard wins this one hands down. Its bamboo cover is removable and machine washable, so you can toss it in the wash after a camping trip. The MLILY also has a washable cover, but it doesn’t specify the material as bamboo, so it’s not quite as premium or breathable.
Is the Milliard or MLILY better for a guest room?
I’d recommend the Milliard for a guest room because it’s a proper tri-fold mattress with a firm, supportive feel that guests will appreciate. The MLILY is a great option if you need a larger Queen size (80″ x 60″) for a bigger guest, but the Milliard’s higher rating and dedicated mattress design make it the safer bet for most overnight visitors.
My Final Verdict
After testing both, the Milliard Full Tri Folding Mattress is my clear winner. It’s a dedicated mattress with a firm feel and a machine-washable bamboo cover, backed by over 19,000 reviews and a 4.6-star average — that kind of track record is hard to beat. The MLILY is a solid runner-up, especially if you need cooling gel memory foam or the larger Queen size, but the Milliard is the better all-around choice for camping and guests.
If you’re still on the fence, ask yourself this: do you want a proven, dedicated mattress that’s easy to clean and trust from thousands of buyers? Get the Milliard. Do you sleep hot and need a cooling gel layer with CertiPUR-US certification? Then the MLILY is your pick.
