Abstract: An apparatus for selectively providing one of a plurality of working surfaces to a person in a wheelchair comprising a planar rigid member with a flat upper surface, a flat lower surface, and an arcuate concave recess formed at its interior edge; a second working surface having an upper surface and a lower surface parallel with the first working surface, and positioned at the outboard end of the first working surface; a plurality of vertically extending walls including an outboard wall coupling the outboard edges of the first and second working surfaces and vertically extending parallel side walls coupling the side edges of the upper and lower working surfaces; a pair of book props secured to the vertical wall at the outboard face of the device with pivot means to allow rotation of the book props independent of each other; and mechanism to couple the lower working surface to a wheelchair.
