Abstract: The conversion of a conventional bed, such as a child's bed, into a play area is accomplished by means of a free-standing enclosure composed of two sub-assemblies of paperboard, each comprising a center panel proportioned to span the width of the bed and a pair of fragmentary side panels hingedly connected to the ends of the center panel. The surfaces of these panels may be provided with representations establishing a desired atmospheric or locational theme, e.g. a castle, a fire engine or a military vehicle. Since the enclosure is free-standing, it can be used independently of a bed to provide a play area, and it is also readily collapsed or disassembled into flat component parts for easy storage.
