Accelsit cushions are ergonomically designed with principles of biomechanics to rectify your sitting posture. The unique structure allows for redistribution of pressure on the spine and buttocks discomfort. Accelsit cushions promote postural alignment and pelvic stability to be an ideal choice in providing optimal sitting comfort and to relieve upper body and back musculoskeletal discomfort. This is especially for long hours in sitting in a limited space. Accelsit cushions are compact, ultra light, and easy-care.
