Abstract: A waterbed mattress has a baffle structure comprising a horizontally extending buoyant pad. The pad is anchored to an underlying anchor sheet that is not secured to the walls of the mattress. A porous mass of bound together fibers is positioned between the anchor sheet and the pad.
Abstract: An air bleeder valve for a waterbed mattress comprises a hollow tubular body sized to fit snugly into the fill spout of a waterbed mattress, a flap valve at one end of the body, and a porous, non-water absorbing water barrier in the tubular body for preventing water from splashing out of the mattress when bleeding air from the mattress.
Abstract: A coupling for filling and draining a waterbed comprises a tube for insertion into the male-threaded filler neck of a waterbed valve, and two female-threaded nuts rotatably mounted on the tube for connection to a garden hose and the male-threaded fill neck of the waterbed. There is a plurality of fill and drain openings through the wall of the portion of the tube inserted into the fill neck.
Abstract: A waterbed mattress has an internal horizontally extending baffle surface for reducing wave-like motion of the water in the mattress. The baffle surface is anchored within the mattress, and preferably between the top and bottom walls of the mattress. Preferably, the baffle surface is fabricated of a buoyant material and is anchored to the bottom wall of the mattress with no connection between the baffle surface and the top wall.
Abstract: Waterbed mattress having an internal floating pad for reducing wavelike motion of the water in the mattress. The pad is fabricated of a buoyant material and is anchored to the bottom wall of the mattress, with no connection between the pad and the top wall.
