This is a wheelchair cushion for caregiving. It is the Reflex model. It was purchased for around 30,000 yen, used a few times, and then stored in a dark place for several years. The name was written in marker on the English tag on the back, so it has been cut off. It is an older item with some scratches and dirt, but the elasticity is still firm. How about trying it out? 40 x 40 x 8 cm Immediate purchase is OK, and it will be shipped within 1-2 days. Thank you!
