A closer look

Sitting perfectly still for hours isn't relaxing; it cuts off blood flow to the skin pinned beneath the ischial bones, causing the flesh to literally die and rot inward. To prevent these lethal flesh wounds, paraplegics rely on highly engineered air-cell cushions like the Roho. These shifting pockets of air continuously redistribute pelvic weight, mimicking the micro-movements of a walking person and keeping the gluteal tissue aggressively oxygenated.
