A base having a top surface, a bottom surface, and a shape symmetrical about a fold line defining first and second halves is selectively moveable between an open position and a closed position. A substantially concave shell has an open bottom defining an outer periphery which is releasably attached to the top surface of the base. A resilient frame member supports the shell above the top surface of the base to define an interior volume between the base and the shell when the tent is in the open position. The shell and the resilient frame member collapse and fit between the first and second halves of the base when the two base halves are moved to the closed position. The base extends beyond the outer periphery of the shell, providing an area for the user to enjoy while being protected from the support surface.
