A first playpen enclosure that converts easily to a bassinet, changing table or bed-side crib or “co-sleeper” that attaches securely to the parents' bed. A second enclosure support system maintains a padded enclosure and rigid floor panel at one or more predetermined levels below the top of the playpen to form the bassinet and co-sleeper. The second enclosure has a back, two sides, a bottom and a front flap that converts into a front wall for use in the bassinet mode and overhangs the front horizontal rail for use in the co-sleeper mode. The upper front corners are segmented into a movable section and a fixed section to facilitate lowering the front horizontal rail to at least one lower second position to accommodate various parental bed heights. Extensions of the fixed section are affixed to the front vertical rails and accept the movable sections in several positions to secure the rail in the second positions. The support means, padded enclosure and rigid floor panel complete the changing table with the edges of the front flap secured to the edges of the side walls. The playpen is placed adjacent the parents' bed with the front flap extended over the bed for use as a co-sleeper. Means are provided to secure loose flap material to the front of the co-sleeper. For co-sleeper use, reinforcing straps secure the unit to the parents' bed and prevent movement. The unit is easily folded with its components into a compact carrying case for transport or storage.
