I have had back problems for years and go to Dallas to pain management once every month...My daughter has a Tempurpedic mattress and it feels good to lay on. Now your going to laugh on this one...I have a waterbed, and its the only bed that brings me comfort. I have a memory foam topper that is 3" thick on the top and 2 egg crates under that, lol...but I tell you, when I sleep out of town or on anything else..I wake up stiff and feeling crippled. I wouldn't trade anything in place of my waterbed. So thats my story...and I'm sticking to it
