Abstract
A folding tablet arm attachment mounted on a metal folding chair which has a ganging feature includes an elongated rectilinear tubular attachment member which has longitudinally spaced apart female keyhole openings formed in a sidewall thereof and internally reinforced for mating coupling engagement with male ganging studs mounted in cantilever position on a rectilinear siderail of the chair whereby the folding tablet arm attachment is positioned and supported on the chair. Fastening tabs carried by the attaching member and disposed in overlying engagement with the chair siderail are fastened to the siderail and releasably secure the tablet arm attachment to the chair to provide a firm working or writing surface for a person seated on the chair.
