This invention is a portable play platform which may be attached or detached to commercially available children's playpens or cribs, giving the child a playing surface to play upon while the child is standing. In general, the device is comprised of a playing surface member usually mounted on the top of the playpen or crib by a bracket attached to the bottom thereof. An adjustable hook-like compression member attached to the playing surface member clamps the upper portion of the playpen against the bracket and a broad torque reaction bar secured between the brackets adjacent to the playpen bears against the playpen thus securing the device rigidly into position. Bolts with wing nuts may be provided to tighten the compression member so as to hold the bracket, and compression member rigidly against the playing surface member.
