  • Decent mattress
Size: SF (52 x 73 Inch) Style: Slow Rebound Memory Foam
Update: The seller corrected the issue I really wanted to like this mattress because the material feels nice and it seemed like good quality when I first got it. The fabric is soft and it came packaged well with everything included. The big problem though is that its been a month and the cushions are still flat. I've had it for over a month now and they're still pretty flat. They never get to where they should be. This makes sleeping on it pretty uncomfortable because it's all uneven - some parts are higher than others and you can definitely feel the difference when you're lying down. It's not terrible for short naps but I wouldn't want to sleep on it all night. The materials seem solid, just something with how the compression. If you're looking for something for occasional use and don't mind it being a bit flat, it might work okay. But if you need something that actuallybounces properly for real sleeping, I'd probably look elsewhere. ... show more

  • Comfortable
Size: C (31 x 75 Inch) Style: High Support Foam
We got this to use for when my parents came to visit. I didn't know what to expect but we have a queen size bedframe that separates into 2 single size cots. These fit well on the cots and were surprisingly very comfortable. Iv used the cots and this to sleep on twice already and felt like I was sleeping on a firm mattress. We've had this for about a month 1/2 now. My husband has degenerative discs disease and uses this on the floor when he wants to watch tv or play video games daily. He absolutely loves it and has been using it on top of our current mattress and wakes up with little to no pain some nights. I use this also and wake up feeling great with no pain as well. We will be using this with camping this summer replacing an air mattress. It is a thick foam and has so far retained its shape with daily use for a month 1/2 now. my only complaint is that the seams are coming apart a bit on the sides but that's easily fixed with a bit of sewing. When folded up its about a 1ft 1/2ft high and will fold and can be stored under a bed that's at least 14in high I believe. I could be off. ... show more

  • Apparently it's really comfortable.
Size: S (25 x 75 Inch) Style: High Support Foam
The media could not be loaded. I built a sleeping platform for my SUV so that I can car camp without pitching a tent. Spent a night in the car to test it out and I woke up with a sore hip. I decided to give this mattress a try and it worked out perfectly. It was cut to the exact dimensions as my sleeping platform that I built and it folds away neatly. On NYE, a friend decided to spend the night in my car in the garage. His original plan was to sleep a few hours and leave at 6AM. Turns out the mattress was so comfortable that he slept till like 11:30AM. I also tested out the mattress a couple time and last night's sleep was excellent. I laid a yoga mat on the floor with a foam sleeping pad over it and the folding mattress over that. It gave my spine excellent support last night and I am considering getting rid of my mattress in my room so that I have more space. ... show more

  • 👌 Exactly what i wanted, takes a few days to fully expand but U CAN sleep on it right away
The media could not be loaded. Been sleepin on it Almost 2 weeks now and its very comfy.. ..dont feel the seems.. we have on the floor Bc even in winter the bedroom gets hot So we often sleep in the living room.. . Before we had a big ole hefty one that Recently, after movin it for party we decided we needed an easier one.. This is PERFECT 👌.. very supportive and easy to fold away off to side, or carry Upstairs without knocking all the pictures off the wall🤣 I like that the cover can be washed.. The colour is slight bluish based grey.. Its hefty but easy enough for 1 person to Handle... It comes w/ air sucked out in a very manageable box.. Only neg is its a lil chem smellin first week But we ignored it.. Though ours is on the floor, it could work Easily w/ our zinus frames ( they come as 2 strong yet light pieces folded like a suitcase that you quickly bolt together) This could be a quick to put up n take down Combo if you wanted a temp bed at reg height ... Price seemed a tad steep but its good quality foam like our other beds and price Is on par with that.. Great for a temp bed or watchin movies.. We just laid a comforter over it.. Id buy again.. 🛏🛏🛏🛏🛏 ... show more

  • Not 4"
Size: SQ (58 x 78 Inch) Style: High Support Foam
I knocked a star for lack of foam but it's still a good product. Middle is 3.5" sides are 3" quite a bit of foam missing on this but still very comfortable as a mattress topper, decent as a futon sofa against a wall, doable as a mattress if you are not a side sleeper. I'd buy again under certain circumstances but not my first go to choice if I had options. If this was labeled 3" and probably $20 cheaper I'd say definitely worth it. I do like the bag it came with assuming it fits when I go to use it. I'm going to always throw it in my truck on trips in case we get stranded. Would make sleeping in the bed much better. Very light weight but the handles don't seem to be well sewn on. Pretty sure they will break in a month or two, but no a big deal. This dies fit really well on a sofa bed. That is what I'm using it for. Pull bed out and put it on top of sofa mattresses. It's a bit long but makes it so much better. ... show more
