A base panel flexibly coupled to the back panel and retained within a second compartment of the cover with the central panel and the base panel defining a notch. A central panel may be flexibly coupled to the base panel and retained within a third compartment of the cover. An end panel may also be flexibly coupled to the central panel and retained within a fourth compartment of the cover. The central panel and the end panel define a cavity. The base panel, the central panel, and the end panel form a triangular support structure in a deployed position. The base panel, the central panel, and the end panel may also be arranged end-to-end and substantially parallel to the back panel in a stowed position.
