After reading several reviews on this bed, I decided to buy. I was skeptical on buying a mattress without lying on it in the store, but I was desparate to aleve my daily backpain and I bought one morning when I was totally fed up. I don't know how long we have been sleeping on this mattress (probably over a month), but it is AWESOME! I have had severe back pain and 4, that's right 4, major spinal fusions and could not get a reprieve from the pain when I woke up every morning. I really feel like a new person. I still have normal pain that I never expect a mattress to cure, but I feel well rested and can stand up and move in the morning. I needed to evaluate how this mattress helped others with chronic back pain and arthritis and have now discovered that those reviewers were right.
