This topper feels like you are sleeping on a very expensive therapeutic mattress. My husband recently completed a sleep study & was spoiled with sleeping on a sleep number mattress. After looking at the high prices of those mattresses, I was hoping that this topper would give our mattress at home (which is only 2 years old) some new life. It did just that and more-no more complaints from him in the morning! I would highly recommend this topper.
