As a person waking up in pain every morning, this mattress has hit the spot! I sleep well, wake up feeling rested, am not waking up throughout the night and the pain is subsiding little by little. My back feels supported and aligned. So far, we could not be happier. My husband said for the first time in 10 years hes waking up without back pain and we had a sleep by number bed. Could not be happier with the transition!
