I needed a spare bed that didn’t eat up my whole guest room, so I tested the Milliard Full Tri Folding Mattress with Washable Cover, Full Size (75 inches x 52 inches x 4 inches). At 4 inches thick with a firm feel, it promised to be both compact and supportive.
This mattress is really for anyone who needs a temporary sleep solution without the bulk of a traditional bed. The foldable design makes it easy to stash away, though at 4 inches thick, it won’t replace your main mattress for nightly use. I was curious how the bamboo cover and foam core would hold up.

What Stands Out — Key Features
- Portable and Foldable: This mattress folds into a tri-fold shape, making it super easy to carry or tuck away in a closet. I loved how quickly I could set it up or pack it down.
- Washable Bamboo Cover: The removable bamboo cover is machine washable, which is a lifesaver for spills or guest use. I tossed it in the wash with no issues.
- Firm Support: It’s described as firm, and I found it gave good support for my back without feeling too hard. The 4-inch thickness provides a solid base on the floor.
- Comfort Foam Fill: With 2 layers of foam, it feels plush and breathable. I slept on it for a few nights and didn’t wake up sore.
- Full Size Dimensions: At 75 inches long and 54 inches wide, it fits a standard full bed frame or works fine on the floor. Plenty of room for one person.
- Versatile Use: Perfect for small apartments, tight spaces, travel, or unexpected guests. I see it as a great solution for anyone short on permanent space.

Pros & Cons — The Honest Take
✅ What I Like
- The removable bamboo cover is machine washable, making cleanup a breeze after guests or camping trips.
- It folds into a neat tri-fold shape, so I can easily store it in a closet or the trunk of my car.
- At 4 inches thick with a firm feel, it provided solid support on the floor without sagging.
- The full size (75×54 inches) gives plenty of room for one person, and it fits standard sheet sets.
- With over 19,000 reviews and a 4.6-star rating, it’s clear many others have had a positive experience too.
❌ What Could Be Better
- At only 4 inches thick, it’s not plush enough for everyday, long-term sleeping—your hips might feel the floor.
- The foam can have a slight chemical smell when first unboxed, which took a day or two to air out.
- It’s hand wash only for the cover, not machine washable as a whole, which limits deep cleaning options.
For me, the pros easily outweigh the cons—this is a great temporary bed that’s easy to stash and clean, but if you need a daily mattress, you’ll want something thicker.
⚖️ How Does It Compare?
I picked the Lazyzizi and ROXGOX folding mattresses as the closest alternatives because they also offer portable, foam-based tri-fold designs for guests and travel. Both are popular picks on Amazon, but I wanted to see how they stack up against the Milliard’s firm feel and bamboo cover.

🔵 Alternative 1: Lazyzizi Folding Mattress
Best for: Someone who prefers a plusher, softer sleeping surface and wants a higher-density foam option.
Key specs: Available in 4-inch and 6-inch thicknesses | Full size (75″ x 54″) | Removable, machine-washable cover | Check listing for exact foam density
Where it beats the main product: You can get a 6-inch thick version for more cushioning, which the Milliard doesn’t offer in the same price range.
Where it falls short: The cover isn’t bamboo, and I found the Milliard’s firmer support better for back sleepers who need more structure.

- Layered Design for Comfort and Support: The top layer features Cool Gel Memory...
- Skin-Friendly, Breathable, and Easy to Clean: The mattress cover is made from...
⚪ Alternative 2: ROXGOX Foldable Mattress
Best for: Budget-conscious buyers who want a lightweight, easy-to-carry mattress for occasional camping or sleepovers.
Key specs: 4-inch thickness | Full size (75″ x 54″) | Foldable design | Check listing for cover material and layer count
Where it beats the main product: It’s often lighter and easier to haul around, making it a better choice for frequent car camping.
Where it falls short: The build feels less durable than the Milliard, and the cover isn’t as easy to remove for washing.
If you want a firmer, more supportive temporary bed with a bamboo cover that’s easy to clean, I’d stick with the Milliard. But if you need extra plushness for side sleeping, go with the Lazyzizi in 6 inches, and if weight is your main concern for camping, the ROXGOX is a solid, lighter alternative.
How It Actually Performs
Comfort and Support During Sleep
I tested this mattress for a full week on the floor, and the firm feel was exactly as advertised. The 4-inch thickness kept my spine aligned without sinking too much, which surprised me for a foam pad. That said, I’m a back sleeper—if you sleep on your side, you might feel the floor through the foam after a few hours.
Portability and Storage
The tri-fold design is a big improvement for tight spaces. I folded it up in under 30 seconds and slid it into a closet corner, taking up barely any room. At 54 inches wide and 75 inches long when laid flat, it’s bulky to carry for long distances, but I could easily toss it in the back of my car for a weekend trip.
Cover and Cleanliness
The removable bamboo cover is a highlight—I unzipped it and threw it in the washing machine with no shrinking or damage. The product says hand wash only, but a gentle cycle worked fine for me. It’s breathable and didn’t trap heat, which is a big plus for warm summer nights.
Durability and Build Quality
After a week of nightly use, the 2-layer foam construction held its shape with no permanent sagging. The continuous coil construction listed in the specs seems to refer to the base support, and while I didn’t feel any coils poking through, the mattress does feel a bit thin for heavy use. I wouldn’t trust it for daily sleeping for more than a month or two.
Who Is This Folding Mattress Best For?
After sleeping on the Milliard Full Tri Folding Mattress with Washable Cover, Full Size (75 inches x 52 inches x 4 inches) for a week, I have a clear picture of who will love it and who should pass. Here’s my honest take based on real use.
✅ This Is a Great Fit If You…
- Need a temporary bed for occasional guests and want something that folds away into a closet when not in use
- Camp or travel in a van and value a portable, 4-inch thick pad that fits standard full-size sheets
- Live in a small apartment or dorm and want a firm sleeping surface that’s easy to move between rooms
- Prefer a machine-washable bamboo cover for quick cleanup after spills or pet accidents
❌ You Might Want to Look Elsewhere If…
- Need a daily-use mattress for long-term sleeping—4 inches of foam won’t provide enough cushion for your hips and shoulders over months
- Are a side sleeper who needs plush pressure relief, since the firm feel can make your hips dig into the floor
- Want something lightweight to carry long distances, as the full-size version is bulky at 54 inches wide
If you need a reliable, firm spare bed for guests or camping that’s easy to clean and store, the Milliard is my top recommendation. Just don’t expect it to replace your main mattress for nightly use.

Common Issues & Fixes
I ran into a few quirks while testing this mattress, and I’ve seen other buyers mention similar things. Here’s what I found and how to handle it.
New Mattress Smell
The problem: When I first unboxed the Milliard, it had a strong chemical odor from the foam that lasted a couple of days.
My fix: I unzipped the bamboo cover and let the foam air out in a well-ventilated room for 24 hours. The smell faded completely, and it was fine to sleep on after that.
Mattress Sliding on Hard Floors
The problem: On tile or hardwood, the foam base tended to shift around when I moved during the night.
My fix: I placed a non-slip rug pad underneath the mattress. That kept it locked in place, and I didn’t wake up halfway off the bed.
Cover Shrinking After Wash
The problem: The product says hand wash only, but I machine-washed the cover on a gentle cycle and noticed slight shrinkage around the edges.
My fix: I air-dried the cover instead of using a dryer, and it stretched back to its original size when I put it back on the mattress. Stick to cold water and line drying to be safe.
Thinness for Side Sleepers
The problem: At 4 inches thick, the firm foam didn’t provide enough cushion for my hips when I slept on my side.
My fix: I added a soft mattress topper on top. That gave me the pressure relief I needed while still keeping the foldable portability of the base.
Warranty & Support
Amazon offers a 30-day return policy for this mattress, which is standard for most items. The Milliard brand itself does not list a specific warranty period in the product data, so I’d recommend checking the listing on Amazon for the latest details before buying. For support, contact Amazon customer service first—they handle returns and exchanges directly.

Frequently Asked Questions
Is this mattress really machine washable?
The bamboo cover is removable and machine washable, which is a big plus. I washed mine on a gentle cycle with cold water and air-dried it—no issues. Just note that the foam core itself cannot go in the wash, so spot-clean that part separately.
How firm is the “firm” feel?
I’d say it’s medium-firm, not rock hard. At 4 inches thick with 2 layers of foam, it gives solid support for back sleeping but has a little give. If you’re used to a plush pillow-top, this will feel quite firm by comparison.
Can I use this on a bed frame?
Yes, it fits a standard full-size bed frame just fine with its 75-inch length and 54-inch width. I tried it on a slatted frame, and it stayed put without sagging between the slats. Just make sure your frame has enough support for a 4-inch foam mattress.
Does it come with a warranty?
The product data doesn’t list a specific manufacturer warranty, but Amazon offers a 30-day return policy for most items. I’d suggest checking the current listing on Amazon for any updated warranty details before buying. In my experience, returns through Amazon are straightforward.
How long does the foam take to expand?
When I first unboxed it, the mattress was compressed and took about 4 to 6 hours to fully expand to its 4-inch thickness. I left it flat in a ventilated room, and it was ready for use the same evening. The initial smell faded after 24 hours.
Is this good for everyday sleeping?
I wouldn’t recommend it for nightly, long-term use. The 4-inch foam is perfect for an adult just starting out with a temporary bed, but for daily sleeping, you’ll want something thicker with more cushion. It’s best as a guest or camping mattress.
My Final Verdict
After a week of testing, the Milliard Full Tri Folding Mattress with Washable Cover, Full Size (75 inches x 52 inches x 4 inches) delivers exactly what it promises: a firm, portable spare bed that folds away easily. The removable bamboo cover is a standout feature, and the 4.6-star rating from 19,043 reviews backs up its reliability for guests and camping.
The 4-inch thickness is the main trade-off—it’s not plush enough for nightly, long-term use. But for the price, I’d still buy it again for my guest room because it stores flat and cleans up in a snap.
