Abstract: The present invention pertains to a novel swimming pool playpen means comprising a foraminous enclosure adapted for suspension in a body of water such that its bottom portion can be operably positioned a pre-determined relatively shallow depth beneath the surface of the water. One preferred embodiment includes adjustable support means for resting the playpen upon the water bottom and another preferred embodiment is directed to flotation means operably connected to the playpen for suspending it within a body of water and whereby it can be conveniently relocated with very little effort. The enclosure portion of the present swimming pool playpen is preferably constructed of a rigid tubular frame over which a foraminous material is mounted.
