Abstract
A chair primarily for use by persons with spinal chord injury, comprises a universally positioned chair back and a universally positioned front support. Users sit upright and are held between the chair back and front support. Both the chair back and front support have sides to prevent users from falling to their sides. A tray also may be attached to the front support. The seating surface also adjusts vertically to the base and floor. Articulating arms attach the chair back and front support to other chair parts. The arms allow easy vertical, horizontal and angular movement of the chair back and front support, and the arms can be locked to secure the back and support.
