A rigid, open-ended enclosure, essentially defining a split or interrupted cylinder, is mounted for rotation around a fixed mattress support which extends between and is held by head and foot leg structures. A pair of end walls, fixed relative to the rotatable enclosure, terminate the enclosure at its ends. The split or interruption provides an access opening and by rotating the enclosure through 360 DEG to different predetermined positions the accessibility to a child in the crib may be varied and at the same time the extent to which that child is confined or retained may be varied. In one of the positions, the access opening lies below the mattress support thereby maximizing the confinement effected by the enclosure and, of course, minimizing the accessibility. |
