Abstract
A waterbed mattress has a baffle structure formed of a buoyant pad capable of floating freely within the mattress and a plurality of chambers attached to the pad. An upper portion of the chambers depend from the pad and are attached to the undersurface thereof. A lower portion of the chambers are attached to and depend from the upper chambers. There are openings conecting the upper and lower chambers for the passage of water therebetween when the weight of a person is placed upon the mattress. The pad and chambers have sufficient buoyancy that the baffle structure floats within the waterbed mattress.
