My grandson is 24 years old, he was diagnosed at birth with Cystic Fibrosis. He is very thin, breathing is difficult, he goes in hospital every 3 - 4 months. I bought the Bodipedic 2-inch gel memory foam topper for him, hoping that it would help him rest easier. He has loved it from the first night he slept on it. His bones and muscles are cushioned all night long. It was easy to unroll and had no bad odor. It was tricky to get the topper and protective skirt together, but i managed by myself and I am 70 years old. I absolutely rate this product as five star, and excellent.
