Absolutely amazing! We have bought SO many beds because no matter what we buy my husbands back still continues to hurt him. He was getting to the point he was sleeping on the couch all the time because he would be in so much pain if he slept in bed. So I bought this on a whim and it’s awesome!! He sleeps like a baby and doesn’t wake up all sore or aching. He said this is the best bed ever and I have to agree
