  • Amazing
Style: 12 Inch Size: Twin
Love this mattress. Bought it as an extra mattress to use while having a hip replacement. Now I don't want to go back to the main bedroom! Great value, great support and not to firm. The edge is a little soft but manageable. Easy to set up and ready to sleep on in a day. It does itself! Love it

  • Comforable
Style: 12 Inch Size: King
Hard to find fitted sheets but extremely comfortable. Helped with back issues immediately. Amazing price. No springs that are eventually stabbing you in the side. Suggested 2 to 3 day expansion time. Perfect balance between a soft comfort layer and being overall firm

  • Great value for the price!
Style: 12 Inch Size: Twin
It was really fun to unpack this giant expanding marshmallow of a thing, and watch it unfold and puff up. Here's a word of advice: Position this mattress in an open space to self-inflate, because with some force it will burst forth as you open the sealing with the provided opening tool. I have a traditional box spring under this fresh new mattress for a nice puffy high bed. But it is intended to stand alone with no underlayment. I don't think it would be rigid enough for comfort on a frame held up by slats because of the spaces, but it would be fine (and probably even better) with a platform frame or plywood sheet, or on the floor. It is ingenious how this 12" mattress is compressed into a shipping box. It smells clean and is comfortable. I slept well on it. I like everything about this mattress except one thing. The thicker mattress has taller spring coils, but not thicker inches of memory foam. If it had a thicker memory foam layer and shorter coils it would be perfect. ... show more

  • A Bed in a Box
Style: 10 Inch Size: Twin
Who knew you could get such a quality mattress in a box? I needed a twin for my spare room so I thought why not try. It was easy to unwrap & place on base . I got the 10” medium & it has gel & memory foam. Comfortable yet firm enough ,no smell or noise. Seems very well made

  • Great value
Style: 12 Inch Size: Queen
I have to purchase 5 queen mattresses for a renovation project so value was important. Bought one of these to see if it would work and it is great. Great quality and price is right. Will be purchasing the 4 others.
