Great product

    • DONT WASTE YOUR MONEY
Just listen to the reviews and ignore the price ! I let this air out for 72 hours and it’s absolute trash. The ad is misleading as there is metal springs in this mattress, which are very uncomfortable as the “memory foam” is essentially non existent. There’s no edge support at all and the mattress heavily dips. ... show more

    • Not worth it
I would not recommend I wanted a firmer mattress and I can feel the mechanics inside the mattress. I purchased a gel mattress pad as well to provide extra support. Have not had it 90 days and it is not returnable

    • The mattresses too hard
The matches is hard. We thought it would be a lot softer by the look of it, but you get what you get by buying and not going out.

    • Not good
I am very unhappy with the mattress. Not firm at all no good quality very lumpy. The instructions states let it set for 72 hours which is 3 days. I let it set for 96 hours which is 4 days. DO NOT BUY!
