This is a set of two air cushions. ① 890mm (length) x 585mm (width) x 40-50mm (height, when inflated), light green ② 410mm (length) x 410mm (width) x 40-50mm (height, when inflated), light maroon Both have been used about three times, just for fitting. Cushion ① has stains as shown in the photo due to poor storage. Cushion ② has no noticeable scratches or stains. The category is pressure sore prevention supplies, but they are not considered pressure sore prevention equipment for welfare services.
