Therafin’s versatile Adjustable Height Channel Bracket is attached to a Therafin half tray that is upholstered with black satin vinyl over 1″ thick foam, on a 1/2″ thick wood base. It’s easy to wipe clean, and all materials are latex free. Recessed cupholder. The bracket slides the tray on from the front, and flips the tray up and out to the side for easy transfer. Bracket fits many standard armpads with maximum dimensions of up to 2-1/2″ wide by up to 1-1/2″ tall. Trimline shape half trays have a straight outer edge that offers support for people with weakness on one side and allows more belly clearance. Included recessed cupholder.
