After sleeping on this mattress for a few nights my husband has decided that THIS is now our mattress.  He has had back issues for a long time and always woke up with his back stiff and hurting.  But since sleeping on this mattress for a few nights he has woken feeling refreshed and ready.  I can attest to the fact that he has had a few nights of a good , sound sleep.  The mattress is soft yet firm enough for him to feel the difference.  Its perfect for him.  We are Very pleased with this mattress! [This review was collected as part of a promotion.]
