ABSTRACT:
A revolvable playpen including a hollow body having an open upper end and a bottom. The bottom of the body has an annular extension substantially normal to the wall of the hollow body and secured to the lower under surface of the bottom is a semi-spherical member. The annular extension limits the degree of tilt of the playpen so that an infant within the playpen can safely revolve the pen about the annular extension and rock upon the semi-spherical member without tipping over.
