I am very happy with this but have a problem with the Panda Topper that I bought some months ago. After washing the cover(following the washing instructions) my husband & I battled for approximately half an hour to get the cover back onto the topper.  It must have shrunk and it doesn't move easily over the foam rubber. As we are in our mid 8o's, when it needs washing again we shall have to abandon it and use the foam uncovered. The effort is too much.
