ABSTRACT:
The present invention provides a novel baby crib having means to mount a mattress platform at a variety of selected heights above the floor and a gate stop adjustable between an operative and an inoperative orientation. In the operative orientation, the gate stop prevents the gate from being lowered to its normally lowest position. In the inoperative orientation, the gate stop does not interfere with gate travel. The invention in a first embodiment provides means so that when the mattress is in the maximum height position, the gate stop must be in the operative orientation, thus preventing the gate from being lowered beyond the mattress height position.
