The mattress topper is pretty thick and cushiony. I used it to help get more comfort out of my bed. I hardly notice the mattress topper once I lay sheets on it as cover. I lay down and sink right in, it takes the body shape when you are lying down, and once you are up, it goes back to its shape. I can use this on a king bed, or even a twin bed that I have. I am also going to be using this on my fold-out bed for when guests arrive.
