I purchased our memory foam cover and our memory foam mattress at the same time. I am more of a pillow top or feather bed gal but my fiance really wanted memory foam. I was hoping that this would be a happy medium. I spent as much on the cover as I did the topper but I really like it. It fit perfectly and it's very nice quality. It also helped with the smell of the memory foam. Everyone said to let the memory foam air out but we just let it expand for about an hour, popped the cover on it and slept on it. There was a faint smell but it wasn't even that noticeable. If you are going to get a memory foam topper than I would get this cover.
