Both my husband and I have back problems. We have invested heavily in Sleep Number, memory foam, pillow top, no pillow top, posturepedic, and adjustable mattresses, trying to find something that would work to alleviate the pain of sleeping. Yesterday, we received this Gel Memory Foam Mattress Topper. I couldn't wait to try it! I slept for 7 house without waking--no hip, back or shoulder pain. My husband slept well also. I couldn't believe it, but it was wonderful. Now, I'm crossing my fingers that this continues, and that the pad doesn't loose it's memory or remember the bumps in the wrong places!
