Flotation cover for mattresses










Image Number 3 for United States Patent #4972534.

A mattress cover for use on a conventional innerspring mattress to give the same feeling as is provided by a waterbed, including a liquid-filled flat bladder having a small height from its top wall to its bottom wall. Insulative padding is included in a casing and held in position atop the bladder to reduce loss of a user's body heat to the liquid, and to provide support. The floating sensation imparted by the flotation cover is facilitated by a wall construction being of sufficient thickness to contain the water within a substantially fixed volume. Fibrous material may be arranged within the bladder to damp wave action of the liquid to a limited degree. A liner surroundingly encloses the lower parts of the bladder within the fabric casing to contain liquid leakage.
