This is the "Owl REHA 3D High" wheelchair cushion, designed with ergonomics to provide comfortable seating. This product is particularly recommended for those who have difficulty maintaining their core strength on their own and tend to slide forward, or those who need support for their thighs. In addition to the anchor function that prevents sliding forward, the 3D shape also supports the rear, allowing the pelvis to be upright, which can be expected to maintain a stable seated position even in a wheelchair. I purchased this and used it a few times, and have stored it for about a year. It has been cleaned and disinfected. Comes with a dedicated cover and instruction manual. The retail price was around 36,000 yen. 【Product Name】 Owl REHA 3D High 【Model Number】 OWL24-BK1-4040 【Weight】 Approx. 1.5kg 【Size】 W400 x D400 【Materials】 Body Surface Material: Urethane synthetic leather Inner Material: EXGEL (synthetic rubber), urethane foam Back Material: Non-slip nylon Cover Surface Material: 100% polyester, urethane foam, urethane film Back Material: Non-slip nylon 【Retail Price】 ￥30,800 (tax included)
