ROHO Cushion, Quatro Select High profile, with a cell count of 8x8. I purchased this item used, but I haven't used it much. I have confirmed that it works. There are no problems. The cover has been washed. The main body has been disinfected with alcohol. This cushion prioritizes pressure redistribution and is highly effective in preventing bedsores. Although it is a wheelchair cushion, it can also be used on chairs, car seats, etc., in addition to wheelchairs. Furthermore, it is suitable for preventing lower back pain as it reduces the strain on the lower back.
