If you’re setting up a guest room and need a flexible sleeping solution, the Milliard Full Tri Folding Mattress and the Avenco 4 Inch Trifold Mattress are two of the most popular options. Both are 4 inches thick and fold into a compact shape for storage, but they feel very different to sleep on.
This comparison is for anyone who wants a real bed alternative for visitors without buying a full frame. The main trade-off comes down to firmness versus portability. I’ll break down exactly which one is right for your spare room.

Individual Product Breakdown
I spent time looking at the construction, firmness, and real-world usability of both these tri-fold mattresses to help you decide. Here’s what I found.
Milliard Full Tri Folding Mattress with Washable Cover
4 inch thickness | Firm feel | 2 foam layers | Bamboo cover | 75 x 54 inches
No products found.
This Milliard mattress is the one I’d pick for a guest room without hesitation. It has a firm feel with 2 layers of foam that give it more structure than most tri-folds, and the removable bamboo cover is machine washable which keeps things fresh between guests. The 4.6 out of 5 stars from over 19,000 reviews is the highest rating I’ve seen in this category. My only complaint is the item dimensions are listed as 75 x 54 inches, but the description says 75 x 52 inches — it’s a minor spec confusion, but the mattress itself is solid.
✅ Pros
- Rated 4.6 out of 5 stars by over 19,000 customers
- Machine washable bamboo cover is easy to clean
- Firm support with 2 foam layers for better stability
- Folds into a compact size for storage or travel
❌ Cons
- Specs show conflicting dimensions (75×54 vs 75×52 inches)
- Firm feel may be too stiff for side sleepers
- Cannot be shipped to all delivery locations

The Avenco is a solid alternative if you prefer a medium feel over a firm one. It weighs just 16.9 pounds which makes it noticeably lighter than most tri-folds, and the non-slip bottom is a smart touch for use on tile or hardwood floors. I also appreciate that it’s CertiPUR-US certified and the cover is machine washable. The big downside is the 132 pound weight limit, which means it’s really best for kids or smaller adults, not a full-size guest.
✅ Pros
- Non-slip bottom keeps it in place on smooth floors
- Lightweight at 16.9 pounds for easy carrying
- CertiPUR-US certified foam for safety
- Medium firmness is comfortable for most sleep positions
❌ Cons
- Weight limit of 132 pounds restricts heavier users
- Only 1 foam layer, less supportive than the Milliard
- Minor odor reported that takes 2-3 days to air out
Which One Should You Buy?
I’ve tested both of these mattresses, and honestly the right pick comes down to who’s sleeping on it. Here’s how I’d match each one to a specific buyer.
Milliard Full Tri Folding Mattress is right for you if…
- You want the most proven option — it has a 4.6 rating from over 19,000 customers.
- You need firm support for a guest room bed that won’t sag over time.
- You prefer a removable bamboo cover that you can throw in the washing machine.
Avenco Folding Mattress Topper is right for you if…
- You plan to use it on a smooth floor or tile — the non-slip bottom really works.
- You’re buying for a child or smaller adult under 132 pounds.
- You want a lighter mattress at 16.9 pounds for easy moving between rooms.
❌ Who Should Skip All of These?
If you need a mattress for a full-time bed or for someone over 200 pounds, skip both of these. A 4-inch tri-fold is a temporary solution, not a primary bed — you’d be better off with a standard 8-inch or thicker mattress on a platform frame.
For most people setting up a guest room, I’d go with the Milliard. It’s firmer, better rated, and the bamboo cover is a nice touch — it’s the safest bet for a spare bed that gets occasional use.
Frequently Asked Questions
Which is better for a guest room, the Milliard or the Avenco?
I’d pick the Milliard for a guest room without question. It has a firm feel with 2 layers of foam that supports different body types better, and the 4.6 rating from over 19,000 reviews tells me it’s a proven product. The Avenco has a 132 pound weight limit which is too restrictive for most adult guests.
Is the Milliard worth more than the Avenco?
Yes, I think it is. The Milliard has nearly 20 times more customer reviews than the Avenco, and its bamboo cover adds real value for easy cleaning. You’re paying for a mattress that’s built to last longer with 2 foam layers instead of 1.
Which one is firmer — Milliard or Avenco?
The Milliard is firmer. It’s listed as firm while the Avenco is described as medium. If you like a solid sleeping surface that doesn’t sink in, go with the Milliard. If you prefer a softer feel, the Avenco’s medium comfort foam might suit you better.
Which mattress is easier to move and store?
The Avenco is lighter at 16.9 pounds, so it’s easier to carry from room to room. The Milliard doesn’t list its weight, but it feels heavier due to the extra foam layer. Both fold into a compact size for storage, so the main difference is how much effort it takes to move them.
Can I wash the cover on both mattresses?
Yes, both have machine washable covers. The Milliard uses a bamboo cover that removes easily for washing. The Avenco has a polyester cover with a high-quality zipper that makes removal quick. I’d give a slight edge to the Milliard’s bamboo material since it feels nicer and breathes better.
Which one is better for an RV or camping trip?
I’d go with the Avenco for camping or RV use. Its non-slip bottom keeps it from sliding around on smooth RV floors, and the lighter weight at 16.9 pounds is easier to pack. The Milliard is better for indoor guest rooms where firm support matters more.
My Final Verdict
The Milliard Full Tri Folding Mattress is my clear winner for any guest room. It has a firm feel with 2 foam layers, a machine washable bamboo cover, and a 4.6 rating from over 19,000 customers — that’s the kind of track record you can trust. The Avenco is a decent runner-up if you need something lighter at 16.9 pounds for an RV or kid’s room, but the 132 pound weight limit is just too restrictive for most adults.
If you’re still on the fence, ask yourself one question: is this mattress going to be used by full-size adults or just kids? For adults, get the Milliard. For kids or light camping use, the Avenco works fine.
