Medline 2000 Excel Manual Wheelchair is made of carbon steel frame with rust and chip-resistant chrome plating. Armrests and calf pads are upholstered and padded. This Manual Wheelchair has TIG welding which strengthens the joints, an extra layer of upholstery support prevents sagging. It has desk-length removable arms and chart pocket on the back. Brass inserts reduce stripping from upholstery changes, and a coating on the frame helps us prevent rust and maintain a brand-new appearance.
