Abstract: A crib structure for a child includes a support surface for the child. A plurality of side walls are operatively connected to the support surface. At least one of the side walls includes a door opening and at least one door. The door is laterally slidable substantially in the direction to and from an adjacent side wall, such that the child can be quietly and easily placed into and taken the crib through the door opening without substantial bending or reaching. The sidewalls and the support surface define an interior space therebetween and an exterior space surrounding the sidewalls. At least one of the side walls is preferably composed of a material which is substantially flexible to forces directed substantially from the interior, and substantially rigid to forces directed substantially from the exterior. Step structure is preferably provided beneath the support surface.
