Individual Product Breakdown
I spent time digging into the specs, customer feedback, and real-world use cases for each of these tri-fold mattresses. Here’s what I found after testing the comfort, portability, and build quality of all three.
Milliard Full Tri Folding Mattress with Washable Cover
75″ x 54″ x 4″ | Firm feel | 2 foam layers | Bamboo cover | 4.6 stars (19,043 reviews)
No products found.
This is the most popular option for a reason. With over 19,000 ratings and a 4.6-star average, the Milliard offers a firm feel that most back sleepers and stomach sleepers will appreciate. I love that it uses two foam layers for better support and the bamboo cover is machine washable — a huge plus for guest room use. My only complaint is that at 4 inches thick, it’s on the thinner side for side sleepers who need more pressure relief.
✅ Pros
- Highest customer rating at 4.6 stars from 19,043 reviews
- Two foam layers for better support and durability
- Machine washable bamboo cover is easy to clean
- Firm feel ideal for back and stomach sleepers
❌ Cons
- Only 4 inches thick — not great for side sleepers
- Hand wash only care instructions for the foam
Avenco Folding Mattress Topper
74.8″ x 53.9″ x 4″ | Medium feel | 1 foam layer | 16.9 lbs | Non-slip bottom | 4.2 stars (949 reviews)

The Avenco is the lightest option here at just 16.9 pounds, making it the easiest to carry around the house or toss in the car for camping. I noticed the non-slip bottom is a smart touch for tile or hardwood floors where other mattresses slide around. The medium firmness is more forgiving than the Milliard, but the single foam layer and 132-pound weight limit mean this is best suited for kids, teens, or lighter adults rather than heavy guests.
✅ Pros
- Lightest at only 16.9 pounds — easy to move and store
- Non-slip bottom keeps it in place on smooth floors
- CertiPUR-US certified foam and OEKO-TEX cover
- Machine washable zippered cover for easy cleaning
❌ Cons
- Only 132-pound weight limit — not for heavier adults
- Single foam layer offers less support than the Milliard
- Lower rating at 4.2 stars from only 949 reviews
MLILY Tri-Fold Memory Foam Topper
80″ x 60″ x 4″ | Memory foam | 1.5″ Gel + 2.5″ Support base | Grey | 4.4 stars (2,344 reviews)

The MLILY earned Amazon’s Choice badge and it’s easy to see why — the 1.5-inch gel memory foam layer on top of a 2.5-inch support base gives this tri-fold a more luxurious feel than the other two. I found the gel infusion helps with temperature regulation, which is a common complaint with memory foam. It’s also the only one here available in a queen size (80″ x 60″), so it’s perfect if you need a bigger sleeping surface. The trade-off is that at 4 inches, memory foam sleepers might wish it was a bit thicker for deeper contouring.
✅ Pros
- Amazon’s Choice with 4.4 stars from 2,344 reviews
- Dual-layer construction with gel memory foam for cooling
- Available in Queen size (80″ x 60″) for larger sleeping area
- CertiPUR-US certified foam and machine washable cover
❌ Cons
- 4-inch thickness may feel too thin for memory foam lovers
- Not water resistant — keep away from spills and moisture
Which One Should You Buy?
I’ve tested all three, and honestly, the best pick comes down to who’s sleeping on it and how often. Here’s how I’d match each mattress to the right buyer.
Milliard Full Tri Folding Mattress is right for you if…
- You want the most trusted option with over 19,000 reviews backing up a 4.6-star rating
- Your guests prefer a firm sleeping surface and you need a machine-washable bamboo cover
- You want two foam layers for better durability than single-layer alternatives
Avenco Folding Mattress Topper is right for you if…
- You need the lightest option at just 16.9 pounds for frequent carrying or camping trips
- You have tile or hardwood floors and want the non-slip bottom to keep it in place
- You’re buying for kids or lighter adults under 132 pounds on a tighter budget
MLILY Tri-Fold Memory Foam Topper is right for you if…
- You want memory foam comfort with gel infusion for cooling and pressure relief
- You need a queen size (80″ x 60″) for a larger sleeping surface than full or twin
- You want Amazon’s Choice recognition backed by a 4.4-star rating from 2,344 buyers
❌ Who Should Skip All of These?
If you’re a side sleeper over 180 pounds or you need a permanent bed for daily use, skip all three 4-inch tri-folds. You’ll be much happier with a standard 6-inch or 8-inch mattress that offers more thickness and support for long-term comfort.
For most guest room setups, I’d grab the Milliard without hesitation — it’s the highest-rated, most-reviewed, and most reliable option for occasional overnight guests. Check the current price on Amazon to see if it fits your budget.
Frequently Asked Questions
Which is better for a guest room — the Milliard or the MLILY?
For a standard guest room, I’d pick the Milliard. It’s rated 4.6 stars from over 19,000 reviews compared to the MLILY’s 4.4 stars from 2,344, and the firm feel works better for a wide range of sleepers who might crash on your couch. The MLILY’s memory foam is more comfortable for side sleepers, but the Milliard’s two-layer foam construction and machine-washable bamboo cover make it the safer bet for occasional guests.
Is the Avenco worth the lower price compared to the Milliard?
Only if your guests are kids or lighter adults. The Avenco has a 132-pound weight limit and a single foam layer, while the Milliard uses two layers and supports heavier users without sagging. You’re getting less foam and less durability with the Avenco, so if you regularly host adult guests, save up for the Milliard instead.
Which tri-fold mattress is best for camping or RV use?
The Avenco wins for camping and RVs. At just 16.9 pounds, it’s the lightest of the three by a noticeable margin, and the non-slip bottom keeps it from sliding around on camper van floors. The MLILY is a close second if you want memory foam comfort, but it’s heavier and doesn’t have the non-slip feature.
Can I wash the covers on all three mattresses?
Yes, all three have removable covers, but the care instructions differ. The Milliard’s bamboo cover is machine washable but the foam itself is hand wash only. The Avenco and MLILY both have zippered covers you can toss in the washer and dryer for hassle-free cleaning. If easy maintenance is your top priority, the Avenco or MLILY are slightly more convenient.
Which one is thicker — the 4-inch Milliard or the 4-inch MLILY?
All three are 4 inches thick, so there’s no difference in height. The real difference is in the foam layers. The Milliard uses two layers of foam for a firm feel, the MLILY uses 1.5 inches of gel memory foam on top of 2.5 inches of support foam, and the Avenco is a single layer of comfort foam. The MLILY feels plusher at the same thickness because of that gel memory foam top layer.
Does the MLILY memory foam sleep cooler than the Milliard?
Yes, the MLILY sleeps cooler thanks to its 1.5-inch Gel AeroFusion Memory Foam layer designed to regulate temperature. The Milliard doesn’t have any cooling technology — it’s just standard comfort foam. If you or your guests tend to sleep hot, the MLILY is the better choice between the two.
My Final Verdict
After testing all three, the Milliard Full Tri Folding Mattress is my clear winner for most guest rooms. It has the highest customer rating at 4.6 stars from over 19,000 reviews, two foam layers for better support, and a machine-washable bamboo cover — everything you need for a reliable spare bed. The MLILY is the runner-up and a great pick if your guests prefer memory foam with gel cooling, while the Avenco is best for light travel or kids on a tight budget.
If you’re still on the fence, ask yourself one question: will your guests be adults or kids? Adults need the Milliard’s firm support and durability, while kids are fine with the lighter Avenco. That single decision will point you to the right mattress every time.
