A wave reduction system for a water mattress having a plurality of buoyant chambers sealed on a separation sheet used to divide the mattress interior between an upper and lower water containing chambers. The separation sheet is connected by a welded seam to a top and a bottom sheet of the mattress, and has cut-out portions at corners of the mattress to relieve stress on the welded seam. Passages are located in the separation sheet for communicating with each chamber.
