Features Sized Pocket The unique, fit-to-the-user, U-shaped pocket provides pressure elimination at the ulcer site, while allowing full ventilation through the open back. Sizing the pocket correctly puts maximum pressure on the femurs, removing the danger of the inherent in one-size-fits all, circular cut-outs. Pocket should fit close to the ischials without touching them. Femur Shelves Flat shelves for the femurs allow even distribution of body weight across the length and width of the load-tolerant femurs. They also help to control internal or external rotation of the femurs.

Sling-Fill Base Molded ABS plastic insert fills in the gap created by fabric slings. Creates a flat rigid foundation where needed. Included standard with every Isch-Dish. 1 Each / Each
