Abstract
A free floating wave motion absorber confined within a water bed mattress for firm body support with omni-directional rate control over motion, so that disturbing movements are substantially reduced and virtually eliminated, by a multiplicity of circulation cells that individually restrict both downward and upward water flow, retard depression or sudden bottoming, and that co-act jointly to transfer lateral displacement forces.
