Cradle comprising an upper frame formed of two U-shaped elements articulated to a block to which are also articulated the legs, which are also U-shaped, that support the supporting rack for the bed base, which U- shaped elements of the frame, the legs and the longitudinal members of said rack are divided by the articulation. One characteristic is the fact that the articulated divisions of the U-shaped elements of the upper frame are two in number and are situated in end zones of the transverse section of said elements, such that, when the legs and the halves of the upper frame are folded and juxtaposed, the equivalent lengths of the branches of the U-shaped elements of the upper frame and of the upper sections of the legs that are divided by the articulation, allow said branches and said sections to be folded inwards through a rotation of approximately 90 degree. <IMAGE>
