I bought this for my son who had complained that he wasn't getting a good sleep because of his old mattress. After he slept on it the first time he called me to tell me what a difference it made. He slept through the night for the first time in a long time. Shortly after he got it, he was away visiting friends and his cousin slept in his room. He immediately callled me to ask where I bought it, the brand, etc because he said he hadn't had such a good sleep in years.
