We bought a temperpedic bed and just couldn't get comfortable with it. However, they did honor the 90 day return policy. Bought a select comfort sleep number bed with a pillow top and love it. Took about a week to get the settings right but once we did I've never touched it since.
I've been known to be very wrong on occasion, but I believe if you sleep on your back, you'll love it, but should you sleep face down, the "give" of the material is no good. You'll be a cranky face sleeper.
