A collapsible crib has a framework substantially in the form of a rectangular parallelepiped including front and rear upper and lower rods which are foldable at their substantially central portions. Connecting bars which cross each other in a crisscross relation are pivotably mounted at ends on distal ends of the lower rods. Links are pivotably connected between the other ends of the connecting bars and side rod portions of front and rear frames of the crib framework. When the crib is unfolded or while it is being collapsed, the links are held substantially parallel to side rod portions of the lower rods. One of the upper rods of the framework may be mounted on swing rods so as to be angularly movable outwardly and downwardly, or may be mounted on slidable brackets on the side rod portions of the front and rear frames so as to be slidable downwardly for allowing the baby to be taken into or out of the crib.
