A waterbed mattress cover has a peripheral side and a top releasably attached to the side. Both the cover and side are quilted. The top may be removed from the side so that it may be washed or cleaned. The underside of the top has an opening and there are one or more foam pads insertable through the opening. The foam pads are generally coextensive with the area of the top and include a plurality of layers of foam which differ both in density and in thickness. The foam layers are separated by an air barrier and a layer of reflective foil.
