This memory foam is fantastic. I bought it for my parents who were coming from L.A. The sofa bed has a thin mattress that is very uncomfortable. So, I supplemented it with this memory foam. My parents slept like a dream. I also have one for my own bed. My husband and I could not afford a temper pedic bed so we bought a cheap mattress and this foam. We sleep very well. It is a great buy! My parents are buying them when they get home.
