The Body UP Evolution is a transport chair, caster commode, shower chair and transfer lift sling designed for use by people with balance, lower extremity or mobility disabilities, or spinal cord injury. FRAME (HxLxW): 44 x 35 x 18 inches. This chair has a stainless steel frame with a hinged back so that a person can be loaded from the rear of the frame. The frame separates into two pieces for transport or storage. SEAT: Sling seat that can be raised or lowered. To facilitate loading, the seat can be disconnected from the chair and laid flat on a chair, bed, bench or car seat. When the user is in a sitting position on the separated seat, the frame is wheeled backwards, with the back open, until the arms are on either side of the user. The seat can then be fastened to the frame using buckles similar to seat belt buckles. Once the seat is fastened to the frame, it is raised using a manual hand crank, and the user can be wheeled to the desired location. The Body UP Evolution includes a waterproof pads for use as a shower chair and a commode seat insert that can be used instead of the sling seat so the user can be wheeled over a toilet or commode for toileting. WHEELS: Four swiveling casters. CAPACITY: 220 pounds. WEIGHT: 42 pounds. WARRANTY: 5 year manufacturer's warranty.
