  • Soft but firm
Size: King
Had a mattress for YEARS and it had to be replaced. Thought we would try this since the reviews were good and I really didn’t want to spend 1k on a king mattress. Opened the mattress on my bed frame and let it sit for 2 days, I couldn’t wait 72 hours. At first I thought it was too soft. Than I realized it was because I was use to my old, spring in my back 500lb old mattress. By day 3 of sleeping on it my body thanked me! My body was messed up from my old mattress. This mattress is soft yet firm, cradles the body and if my husband moves….. he’s 6ft 4 big guy….. I can’t feel the mattress shift around to my side like my old mattress. You can feel the individual cushion support and I can really see this mattress lasting about 7-8 years if not a little longer. Highly recommend to someone that doesn’t want to go to a mattress store or spend a lot of money on something that will be replaced in the future, great sleep and great price. ... show more

  • Impossible to box up to return... hence, it can't be returned.
Size: Queen
It states "strong side support", it does NOT even have good side support, let alone strong. It is SOOOO uncomfortable! Also states it is a "medium firm", nope, it is medium at best. Wish I would have purchased the same bed I had purchased a couple months ago for a spare room, that bed is wonderful! You have to return in original packaging! Impossible! First, the cardboard box ripped. Also, I cannot possibly air vacuum a bed to get it to fit in any box. I am not a company who owns the kind of machinery to make that happen! ... show more

  • Great for price
Size: King
Really good affordable bed. Veryyy heavy and hard to get upstairs. Maybe put some handles on the box. Other than that it’s exactly how described. Didn’t take days for it to get to the right size only a couple of hours!
