Early model Molten Power Cushion, normal type, LL size, 40cm x 40cm. This is a rechargeable battery-powered wheelchair cushion for people who use wheelchairs for long periods. It's a cushion that reduces the worry of buttock pain and bedsores during long periods of sitting with its three elements: "pressure distribution," "automatic pressure adjustment," and "pressure relief." Purchased 4-5 years ago. Actual usage was only about 1 month, used 3 times a week for 5 hours during work. There is some use, so it's offered at a bargain price. The cover has no incontinence issues, but it has been home-cleaned and disinfected. The carrying bag for the product is not included. *Because it's an early model, there is no switch window or battery level indicator window on the cover. Normal type (stability-focused) Thickness 8cm (11cm at the thickest part) LL size, width 40cm x depth 40cm Due to the nature of electrical products, we cannot accept any detailed requests after purchase. Please refrain from purchasing if you are overly concerned about details. Manufacturer's explanation: https://www.molten.co.jp/health/products/positioning/power-cushion/
