I’ve been testing three popular queen tri-fold mattresses — the Comtrihion, GEMBED, and Erament — to figure out which one actually works as a guest bed and camping pad. All three use memory foam and fold into a compact shape, but their thickness, firmness, and build quality are very different once you lay on them.
If you’re tired of thin camping pads that leave you sore or bulky guest mattresses that are a pain to store, this comparison is for you. I’ll break down exactly who each mattress is for and where they fall short so you can pick the right one the first time.

I put together a side-by-side spec comparison so you can see exactly how these three queen tri-fold mattresses stack up against each other at a glance.

The biggest difference I noticed is the weight — the Comtrihion is listed at just 1 pound while the Erament is a hefty 25 pounds, which tells me the Erament uses much denser foam for a more substantial feel.
Individual Product Breakdown
I spent time unboxing, laying on, and folding each of these tri-fold mattresses to judge comfort, portability, and real-world build quality. Here’s what I found with each one.
Comtrihion Tri Folding Mattress – Foldable Mattress for Travel/RV/Camping/Road Trip/Guest Room/Yoga
6 Inch Thick | Memory Foam | 78″L x 58″W | 1 Pound | Dark Grey

- 【Skin-friendly and comfortable】The skin-friendly cover of this tri-fold...
This Comtrihion mattress hit the sweet spot for me. At 6 inches thick with high-density memory foam, it offers excellent pressure relief without feeling like I’m sleeping on the floor. The non-slip bottom kept it planted on my hardwood floor, and the tri-fold design with a handle makes it genuinely easy to carry around. My only real complaint is the listed weight of 1 pound seems like a typo — it’s light but not that light — and the cover, while machine washable, feels a bit basic compared to the Erament’s corduroy.
✅ Pros
- 6-inch thickness provides great support for side and back sleepers
- Non-slip bottom keeps mattress stable on any surface
- Amazon’s Choice with a 4.5-star rating from 152 reviews
- Folds and unfolds in seconds with a convenient handle
❌ Cons
- Needs 48-72 hours to fully expand after unboxing
- Cover fabric feels less premium than the Erament’s corduroy
GEMBED Tri Folding Mattress Queen Size – Memory Foam Tri-fold Handle & Non-Slip Bottom

The GEMBED is a proven workhorse with over 529 ratings and an Amazon’s Choice badge, which gives me a lot of confidence in its consistency. I liked the pillow top design — it adds a touch of softness that the Comtrihion lacks. But at 5.5 inches thick, it’s half an inch thinner than the other two, and I could feel the floor more when lying on my side. It’s also noticeably heavier at 33 pounds, so it’s less ideal for frequent camping trips. That said, for a guest room mattress that stays put most of the time, it’s a solid pick.
✅ Pros
- Over 500 customer ratings prove long-term reliability
- Pillow top adds a plush, hotel-like feel to the surface
- Removable cover is machine washable for easy cleaning
- Medium firmness works well for most sleep positions
❌ Cons
- 5.5-inch thickness is thinner than the Comtrihion and Erament
- At 33 pounds, it’s heavy to carry for camping or travel
- Needs up to 7 days to fully expand, longer than competitors

- Plush Support with Premium Memory Foam: Enjoy cloud-like comfort and proper body...
- Superior Cleanliness with Removable Corduroy Cover: Encased in a soft...
The Erament immediately stood out for its premium build. At 80 by 60 inches, it’s actually larger than a standard queen mattress, which is great for taller people like me. The corduroy cover feels soft and looks classy, plus it’s fully removable and machine washable. At 25 pounds, it’s heavy enough to feel substantial but still manageable. My biggest concern is that it only has 5 customer reviews so far, so it’s hard to gauge long-term durability. The medium firm feel is comfortable, but if you like a plush mattress, this might be too firm for you.
✅ Pros
- Largest surface area at 80″ x 60″ — perfect for tall sleepers
- Premium corduroy cover is soft, breathable, and machine washable
- OEKO-TEX certified memory foam for added safety assurance
- Non-slip rubberized bottom keeps it secure on floors
❌ Cons
- Only 5 reviews on Amazon, so long-term reliability is unproven
- Medium firm feel may be too firm for those who prefer plush mattresses
- At 25 pounds, it’s heavier than the Comtrihion for travel
Which One Should You Buy?
I’ve spent enough time on all three to know there’s no universal winner — it really comes down to how you’ll use it. Here’s how I’d match each mattress to the right person.
Comtrihion Tri Folding Mattress is right for you if…
- You need a portable mattress for both camping and guest rooms — the 6-inch thickness and handle make it easy to move around
- You want a non-slip bottom that won’t slide around on hardwood or tile floors while you sleep
- You prefer a proven product with an Amazon’s Choice badge and a solid 4.5-star rating from 152 customers
GEMBED Tri Folding Mattress Queen Size is right for you if…
- You want the most customer-validated option — over 529 ratings give me confidence this mattress holds up over time
- You like a pillow top feel for a softer, more luxurious sleep surface on your guest bed
- You’re setting up a permanent guest room mattress that won’t need to be moved often — the 33-pound weight is fine if it stays put
Erament Folding Mattress Queen Size is right for you if…
- You’re tall — this mattress measures 80 by 60 inches, making it the largest of the three and a better fit for taller sleepers
- You care about premium materials like the soft corduroy cover that’s both removable and machine washable
- You want OEKO-TEX certified foam with medium firm support for better back and joint alignment
❌ Who Should Skip All of These?
If you need a permanent everyday mattress for your bed frame, skip these entirely — a tri-fold is meant for temporary use, not nightly long-term sleeping. You’d be better off with a standard innerspring or hybrid mattress designed to last years of daily use.
For most people looking for a guest bed or camping mattress, I’d go with the Comtrihion. It gives you the best balance of 6-inch thickness, portability, and proven reliability at a fair price point that covers almost any scenario you throw at it.
Frequently Asked Questions
Which tri-fold mattress is thicker — Comtrihion, GEMBED, or Erament?
Both the Comtrihion and the Erament are 6 inches thick, while the GEMBED is 5.5 inches. I noticed that half-inch difference when lying on my side — the 6-inch options kept my hips from hitting the floor, while the GEMBED felt just a bit closer to the ground. If thickness matters most for comfort, go with the Comtrihion or Erament.
Is the Erament worth more than the Comtrihion for a guest room?
It depends on what you value. The Erament has a nicer corduroy cover and is slightly larger at 80 by 60 inches, plus it uses OEKO-TEX certified foam. But the Comtrihion has 152 reviews and an Amazon’s Choice badge, so it’s a safer bet if you want proven reliability. I’d say the Erament is worth it if you want a premium look and feel, but the Comtrihion is the smarter choice for most people.
Which mattress is best for camping and travel?
The Comtrihion is the clear winner for portability. It’s listed at just 1 pound (though it’s heavier in reality), has a built-in handle, and folds up small enough to toss in a car trunk. The GEMBED weighs 33 pounds and the Erament is 25 pounds, so both are too heavy for frequent camping trips. Stick with the Comtrihion if you’re hauling it around.
How long do these mattresses take to fully expand after unboxing?
The Comtrihion needs 48 to 72 hours on a flat surface, and the GEMBED can take up to 7 days. The Erament doesn’t specify an exact time, but expect at least 2 to 3 days for all of them. I’d recommend opening the box in a well-ventilated room a few days before you actually need the mattress.
Which mattress has the most customer reviews and ratings?
The GEMBED has the most by far with over 529 ratings and a 4.5-star average, plus an Amazon’s Choice badge. The Comtrihion has 152 ratings at 4.5 stars, and the Erament only has 5 ratings at 4.8 stars. If you trust crowd-sourced feedback, the GEMBED is the safest pick because so many people have already bought and reviewed it.
Are these tri-fold mattresses machine washable?
All three have removable covers that are machine washable, which is great for spills or guest use. The Erament’s corduroy cover feels the most durable and easiest to clean, while the Comtrihion has a basic fabric cover with a hidden zipper. The GEMBED’s cover is a polyester blend that also removes easily. Just unzip, toss in the wash, and air dry.
My Final Verdict
After testing all three, the Comtrihion Tri Folding Mattress is my clear winner. It delivers the best all-around package — 6 inches of memory foam comfort, a non-slip bottom for stability, and a handle for easy portability, all at a price that undercuts the GEMBED. The GEMBED is a solid runner-up if you want a pillow top feel and prefer a mattress with over 500 reviews backing it up, but the Comtrihion covers more ground for more people.
If you’re still on the fence, ask yourself this: are you going to move this mattress around, or will it live in a guest room? If you need portability, get the Comtrihion. If it stays put and you want a softer surface, the GEMBED is your pick. The Erament is only worth it if the larger size and corduroy cover are non-negotiable for you.
