ABSTRACT:
A water mattress includes an outer bladder for retaining water and an inner chamber assembly for inhibiting wave motion within the bladder. The chamber assembly includes multiple chambers each having a bottom sheet and a closure sheet, and the bottom sheet being deformed to provide the bottom and sides of the chamber. Adjacent chambers are joined along a single seam to form the chamber assembly. In a preferred method, the bottom sheet is heated and drawn into a vacuum form where it is cooled to permanently deform the sheet into an integral, multiple chamber, seamless configuration.
