I've had this mattress for a couple months now, my first me mory foam. A friend said they take alittle while to get used to. It's rock hard and very uncomfortable!! I've tried putting a feather mattress pad on top of it and it's still terible. I wish I would never had purchased it, remember there are no returns!!!!! It was a waste of money. My husband and I have back problems and everyone says it would help and that was not true with this bed!! Nothing like the beds we tried out in all the show rooms. I thought I had done my research before I bought this bed , about pounds of preasure, thickness and such and nothing I've found since is as bad as this bed. I can't wait to get rid of it . Sleeping on the floor is more comfortable. beware!!
