Having slept on the ReST Smart Bed for at least 6 months now I can definitely say this is truly a smart bed, the way it adjust to make sure your body get the rest it needs is incredible. This really is the bed that whether you sleep for 6 or 10 hours you wake up rested and energized. My girlfriend loves the fact that we do not have to settle on one type of firmness as she can customize her side to her preference without me disturbing her when my side customizes on its own, can not go wrong with that!
