  • Surprisingly Comfy Mattress!
Style: 10 Inch Size: Full
This was a last minute purchase for a visit from my in-laws. We didn’t really have time to research and turns out we lucked up! This is a great mattress. It’s just the right balance of soft and firm. And the price is great! I recommend this if you need an inexpensive, good quality mattress.

  • Great mattress.
Style: 12 Inch Size: Twin
I haven't had a new mattress for a long time. I am 70 and suffer from aches and pains in my body at night. This mattress is so comfy that I do not feel all that pain I used to. It is well worth the money.

  • 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

  • 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
