ABSTRACT:
A structure for supporting a mattress in a crib so that it is easily, manually, vertically adjustable and comprising a bracket at each corner of the crib inside the crib, the brackets each having a track or guide for it to slide on and a socket for the reception of a part of the mattress support in an easily detachable manner. Each bracket has a spring-biassed hook on a plate but slidable relative to the bracket and its guide, and notches on the guide receiving the hook so that an upward and then a horizontal motion is needed to free the hook from the guide and allow adjustment of the bracket vertically along the guide.
