Abstract: A foldable playpen having two end portions and two side portions which are interconnected to form a substantially square frame, and a flexible skirt forming a wall thereabout, where the two end portions are pivotable in a downward direction toward a center vertical leg located at each end, and the side portions are pivotable inwardly bringing the two folded end portions together, to thereby fold the playpen into a small, almost square area less than the area of the opened frame. The floor of the playpen is formed of spaced apart, hinged slats covered with a padding protection. The covered slats can be folded into a cylindrical shape which is adapted to receive the folded playpen frame therein, such that the entire playpen can be easily carried, such as by a handle connected thereto.
