Invacare Careguard - Variable Alternating Pressure Pump and Pad provides relief through 21 body support pad tubes. Both the pump and pad are quiet, safe and effective. The 36" x 90" pad is constructed of tough, long-lasting 16 gauge vinyl and has a heavy-duty finish. The pump connection tube is 56" long and has two C hooks for hanging the pump vertically and attaching it to bed rails. For simple operation, the switch is illuminated when the pump is on. If the pad ever wears thin, simply order a replacement pad for continued comfort and protection from skin breakdown. Latex-free.
