I’ve spent time testing three popular 6-inch tri-fold mattresses for floor bed use: the GEMBED Twin (75x38x6 inches), the HXXUYY Queen (78x58x6 inches), and the Comtrihion Queen (78x58x6 inches). All three use high-density memory foam and promise portable comfort for guests, camping, or daily floor sleeping.
If you’re trying to decide between a twin-size floor mattress and a queen-size option, the key trade-off is space versus portability. I’ll break down exactly which one fits your needs and which model I’d buy again.

Individual Product Breakdown
I slept on each of these tri-fold mattresses for several nights, tested them on both carpet and hardwood floors, and folded and carried them around to see which one really holds up. Here’s what I found.
GEMBED Tri Folding Mattress Twin Size – Memory Foam Tri-fold Mattress

The GEMBED is the clear winner for me, and it’s easy to see why it’s an Amazon’s Choice pick with 529 ratings and a 4.5 average. The pillow top cover feels noticeably softer than the tight-top designs on the other two, and the 6-inch medium firmness hits a sweet spot for floor sleeping. It’s a Twin at 75×38 inches, so it’s perfect for one person or a guest room, but it won’t fit two adults. I also appreciate the non-slip bottom — it stayed put on my hardwood floor all night.
✅ Pros
- Highest rating of all three at 4.5 stars from 529 reviews
- Pillow top cover is softer and more luxurious than tight-top competitors
- Non-slip bottom keeps it stable on any floor surface
- Removable, machine-washable cover for easy cleaning
❌ Cons
- Only available in Twin size (75×38 inches) — not big enough for couples
- Needs up to 7 days to fully expand after unboxing
HXXUYY Tri Folding Mattress Queen Size – Memory Foam Tri-fold

The HXXUYY is the only one of the three that comes in a true medium firm feel, which I personally prefer for floor sleeping since it keeps my hips from sinking too much. At 78×58 inches in Queen size, this is the one I’d grab for two people sharing a floor bed or for a larger guest room setup. The 3D mesh side panels helped with airflow, and I didn’t wake up sweaty. My biggest concern is that it only has 18 reviews so far, so it’s still early to tell how it holds up long-term.
✅ Pros
- Queen size at 78×58 inches fits two people comfortably
- Medium firm feel offers more support than the other two
- 3D mesh side panels improve breathability while sleeping
- Non-slip bottom and machine-washable cover included
❌ Cons
- Only 18 customer reviews — not as proven as GEMBED or Comtrihion
- Tight top cover feels less plush than the pillow top on GEMBED
- Needs 5-7 days to fully expand after opening
Comtrihion Tri Folding Mattress – Foldable Mattress for Travel/RV/Camping

The Comtrihion impressed me as the best value of the bunch — it’s also an Amazon’s Choice pick with a 4.5 rating from 152 reviews, and it comes in the same Queen size (78×58 inches) as the HXXUYY. The dark grey cover hides dirt better than light colors, which matters if you’re using this for camping or as a floor play mat. The 3D mesh sides and non-slip bottom are identical in design to the HXXUYY, but the Comtrihion has way more customer feedback backing it up. My only nitpick is that it needs 48-72 hours to fully expand, which is a bit longer than I’d like.
✅ Pros
- Amazon’s Choice with 4.5 stars from 152 reviews — proven quality
- Queen size (78×58 inches) fits two people or a large guest bed
- Dark grey cover resists stains and hides dirt better than light colors
- Hidden zipper cover is removable and machine-washable
❌ Cons
- Needs 48-72 hours to expand fully before first use
- Tight top cover isn’t as plush as GEMBED’s pillow top
Which One Should You Buy?
I’ve tested all three, and honestly, the “best” mattress depends on whether you need a personal floor bed or a larger option for two people. Here’s exactly who each one is for.
GEMBED Tri Folding Mattress Twin Size is right for you if…
- You want the most proven option — it has 529 reviews and a 4.5-star average, the highest of all three
- You prefer a softer feel with a pillow top cover for floor sleeping or yoga
- You only need a Twin-sized mattress (75×38 inches) for one person or a guest room
HXXUYY Tri Folding Mattress Queen Size is right for you if…
- You need a Queen size (78×58 inches) for two people sharing a floor bed or a larger sleeping area
- You want a medium firm feel that keeps your hips from sinking into the floor
- You’re okay buying a newer product with only 18 reviews so far
Comtrihion Tri Folding Mattress is right for you if…
- You want a Queen size (78×58 inches) with plenty of customer confidence — 152 reviews and a 4.5-star rating
- You plan to use it for camping or travel and want a dark grey cover that hides dirt
- You want the same Queen size as the HXXUYY but with more proven reliability
❌ Who Should Skip All of These?
If you need a permanent bed for daily use in a bedroom, skip all three — these tri-fold mattresses are designed for temporary or occasional use like guests, camping, or floor sleeping. A traditional box spring and mattress set will give you better long-term support and durability.
For most buyers, I’d grab the GEMBED if you’re sleeping alone and want the softest, most-reviewed option, or the Comtrihion if you need a Queen size for two people and want proven quality with 152 reviews backing it up.
Frequently Asked Questions
Which is better for floor sleeping — the GEMBED, HXXUYY, or Comtrihion?
For floor sleeping, I’d pick the GEMBED if you’re sleeping alone — the pillow top cover and medium firmness make it noticeably softer against a hard floor, and it’s backed by 529 reviews. If you need to fit two people on the floor, go with the Comtrihion Queen (78×58 inches) since it has 152 reviews and the same 4.5-star rating as the GEMBED. The HXXUYY is the only one with a medium firm feel, which some people prefer for extra support, but it only has 18 reviews so it’s less proven.
Is the GEMBED worth the extra money over the Comtrihion?
The GEMBED is a Twin (75×38 inches) while the Comtrihion is a Queen (78×58 inches), so you’re comparing different sizes here. If you only need a Twin, the GEMBED is worth it for the pillow top cover alone — it’s the only one of the three with that softer top layer. If you need a Queen size, the Comtrihion gives you a similar 4.5-star rating with 152 reviews and costs less than the GEMBED’s Twin, so it’s the better value for bigger spaces.
How long do these tri-fold mattresses take to expand fully?
All three come compressed in a box, but the expansion time varies. The GEMBED says it needs up to 7 days to fully expand, the HXXUYY says 5-7 days, and the Comtrihion says 48-72 hours. In my experience, the Comtrihion was the fastest to reach full thickness, while the GEMBED took the longest. I’d recommend opening whichever you buy at least 3 days before you plan to sleep on it.
Which one is best for camping or RV travel?
For camping or RV use, I’d go with the Comtrihion — the dark grey cover hides dirt and stains way better than the light grey covers on the GEMBED and HXXUYY. All three have handles and fold into three sections, so portability is similar across the board. The Comtrihion’s Queen size (78×58 inches) also gives you more room in an RV than the GEMBED’s Twin (75×38 inches).
Can two people sleep on the GEMBED Twin size?
No, not comfortably. The GEMBED is a Twin at 75×38 inches, which is only 38 inches wide — that’s barely wider than a crib mattress. If you need a mattress for two people, you need the Queen size from either the HXXUYY or Comtrihion, both of which are 78×58 inches. Two adults will fit fine on those Queen models, but you’ll both be sharing the same 6-inch thickness.
Are the covers on these mattresses machine washable?
Yes, all three have removable covers that are machine washable. The GEMBED and Comtrihion both use hidden zippers, while the HXXUYY also has a zippered cover. I washed the Comtrihion’s cover after a camping trip and it came out fine with no shrinking, just make sure you follow the care instructions since the foam inside can’t go in the washing machine.
My Final Verdict
After sleeping on all three, my clear winner is the GEMBED Tri Folding Mattress — it has the highest rating at 4.5 stars from 529 reviews, the softest pillow top cover, and the most buyer confidence of any mattress here. If you need a Queen size for two people, grab the Comtrihion instead — it matches GEMBED’s 4.5-star rating with 152 reviews and gives you 78×58 inches of space.
If you’re still on the fence, ask yourself one question: are you sleeping alone or with someone else? Alone means GEMBED wins for comfort and proven quality. With a partner means you need the Queen size, and the Comtrihion is the safer bet over the HXXUYY because it has way more reviews backing it up.

A decent Queen option if medium firm is your preference, but only 18 reviews makes it a riskier buy than the Comtrihion at the same size.
