My wife and I have experienced several mattresses promising to create a better nights rest and help with joint/back pain, but none can come close to our new ReST bed. We have not experienced sleep like this in decades. The bed adjusts to the pressures your body is placing on the mattress to equally distribute the weight and relieve multiple pressure points. You wake up refreshed and without pain! We purchased a split king which is great considering we prefer different firmness levels. We are now able to adjust each side to our personal liking. It is the perfect bed for anyone looking for a pain free good night’s rest
