The ProX XSA-B2X4W is a White Vinyl Upholstery Removable Waterproof Seat Cushion for 2 pcs of 2 ft X 2 ft LUMOStage™ modules.   Manufactured with commercial vinyl material and foam padding over a plywood base that drops into the LUMOStage™ module in place of the translucent white plastic top.   The corners have a small radius to help prevent vinyl damage.   Each cushion measures 24" x 48" on the outer edges and is approximately 2 1/2 inches thick.

To utilize this double-sized padded seat top, you must use 2 identical pieces of LUMOStage™ Modules.  The seat top is designed to lock the two stages pieces together.
