Abstract: The structure comprises a tray of a substantially rectangular configuration having a telescoping hinged leg mounted to the bottom of the tray at one side thereof and projecting portions on the opposite side extending outwardly to fixedly engage clamp members in mating apertures. The clamp members mount to the side of a lounge chair or chaise while the telescoping leg is extended at a right angle to the tray and rests upon the ground where it is locked place. Alternative clamp members include flexible VELCRO.RTM. fasteners which are inserted through the tray slots and a C-clamp arrangement which surrounds a member on the chair for gripping purposes and is tightened thereabout by a vertical threaded member.
