Abstract
The present invention is a waterbed mattress having a slab of substantially open celled foam or cellulosic sponge substantially submerged in the liquid fill of the mattress. The waterbed mattress of the present invention retains the positive qualities of bouyant support and comfort of conventional waterbed mattresses, and reduces the undesired wave motion often created within the mattress. Other embodiments of the present invention include a waterbed mattress having a large number of substantially open celled foam or cellulosic sponge particles which are substantially submerged in, yet partially suspended at the upper surface of, the mattress's liquid fill, such particles being either enclosed in a gauze-like sack or unenclosed within the mattress. The present invention may be incorporated in waterbeds or other body supporting furniture such as chairs and couches in which a liquid fill medium is used.
