Abstract: A lap tray is amenable to being rolled up into a cylindrical storable configuration, and to being unrolled into a set-up configuration. The tray includes slats mounted on one side of a layer of flexible material, and a brace assembly located on the other side of the layer of flexible material. The brace assembly includes brace elements connected to the slats by a pivot pin and are in an X-shape when supporting the slats in the set-up configuration. The rolled up tray is carried and stored in a carrying case.
