发明名称 Damping chamber for waterbed mattress
摘要 The present invention provides a damping baffle for damping the wave action in a waterbed mattress. Each baffle is fixed to the mattress, and has an upper and lower chamber designed to provide firmness yet avoid undue stress on the weld between the mattress and baffle. The lower chamber is shorter in height and has a greater number of flow-permitting apertures than the upper chamber.
