One of the selling features was the vibration- they failed to tell me it shuts off after 30 minutes- so what kind of relief is that? I called the store to return it after one night and they said no returns after it leaves the store! Friends were talking about beds and the other friend got a sleep number that vibrates and she is very satisfied and hers stays on indefinitely. I could not say I feel that way at all- so I guess the other friend will get a sleep number bed.
