  • I really like this mattress
Size: Full Style: 10 Inch
So thankful to find an affordable mattress that is also comfortable. I wanted a firm mattress, and this fits the bill. Very comfy too. I also appreciate the handles on the side for those times you rotate your mattress

  • A really comfortable mattress for our RV, and at a great price
Size: Queen Style: 8 Inch
We needed a new mattress for our RV. Our challenge was the thickness of the mattress. We were only able to have it 8" thick and found this one on Amazon by Serweet. It came packaged tight, so we were able to get it into our RV and when we opened it up, we were so surprised by the quality. We have taken two trips since receiving the mattress and are so pleased with how comfortable the mattress is. Could not be happier. ... show more

  • Great for the price
Size: Queen Style: 12 Inch
I love how comfortable this mattress is. I recently had such a horrible mattress and I upgraded to this and am so glad I did. My only gripes are that the edges of the bed are so soft that you can’t really sit on the edge, and that the mattress is a little unshapely on the corners. This mattress is so comfortable otherwise and I no longer have back pain. It’s still not firm enough for stomach sleeping because your back will cave and ache all day, but side and back sleeping it is perfect for. ... show more

  • So Far So Good
Size: Queen Style: 10 Inch
Probably my favorite purchase of my adult life lol I've been sleeping on the same 20+ year old mattress since college and it has been doing a number on my back, but I've been hesitant to buy a new mattress because what if it's uncomfortable after costing me an arm and a leg? Thanks to the price of this mattress I was finally willing to throw out the old dinosaur. I couldn't believe this thing (I got a queen) fit in such a slim box and even though instructions were included, I didn't pay attention. Big mistake. When I released the mattress from its vacuum seal it unfolded with enough force it almost took my head off. Totally my fault and I got a good laugh out of it. Seriously though please be careful. I let the mattress sit for three days so it could puff up, but from the get-go it already felt plenty firm. I was concerned that the corners and sides would be a little too soft and flat, but I haven't had that issue. I also took someone's advice and put cardboard boxes on my frame to fill in the gaps and give it more support. Went a little extra and also got a fluffy mattress topper and now, after a week of sleeping on this mattress, I am in love. It's perfectly firm, but not too much. I'm already no longer waking up with lower back pain. Honestly I have nothing but good things to say about this mattress. It feels fantastic and far exceeded my expectations. I'm so relieved I didn't have to shell out a couple grand for a mattress. The real question is how long it will last, but with the price I won't care if I have to replace it every couple of years, it will still be saving me money in the long run. Also of note, the box it arrived in was nearly destroyed in transit. Come on UPS get it together. It looked like the box had been tossed down a couple hills. I was freaking out that my mattress was damaged, but inside it was packaged so well that I found not a single tear or sign of damage. Big plus in my book when sellers package their stuff securely. ... show more

  • 6 month review

I can say This mattress is legitimately just as good if not better than the one I paid $1300 for. I have a Queen and have had it for 6 months now and it is so comfortable.

  • Nice bed!
Size: King Style: 12 Inch
I love this mattress! We’ve been using it about 6 months and I’m sleeping through the night again. Since it doesn’t giggle or move I can’t feel my husband get up through the night. He’s sleeping better as well. Very happy!

  • Initial Experience Very Good
Size: Queen Style: 10 Inch
I had no high expectations, but I'm quite pleased. I'm 6'3" and over 300 pounds. I would never call this mattress firm. But also not soft. I think the best description is resilient support. Certainly no sag. The edges could be firmer, but that's something you give up in a budget mattress. Still, no worse than our old all latex. Unboxing and setup was painless. It's a heavy box, so make sure delivery can get to your porch. If you can't handle a heavy box, pay the extra for delivery to the bedroom or full setup. It is compressed and then rolled. The roll is held merely by a single layer of plastic wrap secured by tape. When you remove the tape, the mattress can be rolled out, still compressed. It's not going to slap you or anything. It's just a rolled mattress. As you remove the inner plastic, you can hear it taking in air. We stood it against the wall to inflate. It was nearly full size before we could stand it up. We left it there overnight and moved it to the bed before noon when it looked and felt fully inflated. There has been no odor. This mattress at least has pulls on the sides, which our old one did not. The workmanship looks very good. It's quite nicely finished and detailed. I'm pleased with the price point. I expect it will be good for at least three or four years, which is enough at this low price. I'll update this with some sleeping experience and anything that is less than good. ... show more

  • Somehow too soft and too firm at the same time
Size: Full Style: 12 Inch
I researched mattresses for our guest room for a while before deciding on this one. We were replacing a 17 year old TempurPedic and needed something to keep guests comfortable when visiting. I decided to test it out for a few nights to see how it feels. The mattress setup easily and inflated without issues. However, the edges are so soft that they dip down (it would be easy to roll off if you are a mover in your sleep) and the center is rock hard. I can feel the coils - which many other reviews said they could not feel coils and the bed was the perfect balance of firm and soft. It is also HOT. Even with a cooling mattress topper and cooling blanket, I wake up sweating. I made it three nights on this mattress before wishing I hadn’t already gotten rid of the 17 year old mattress. This thing is uncomfortable, which is such a disappointment. ... show more
