Price reduced! Thank you for viewing. ★ Wheelchair Pressure Redistribution Cushion I purchased this based on the recommendation of a physical therapist for elderly care. The cushion is approximately 6-7 cm thick. It measures approximately 40cm in both length and width. It was helpful when the user was thin and the bones were pressing against the seat. Used for about a month. (Due to the increase in the level of care) After that, it has been stored at home by a non-professional. Please consider this if you understand. Thank you.
