Jointed sommier for sofa-bed, characterized by comprising six sections articulated to each other, the first of which is constituted by two profiles that serve as support base of the sommier in the closed position, these two profiles being rigidly joined to two corresponding lugs or protrusions of the frame of the sofa or armchair, and in addition, for each of its ends and articulates that at its other end are joined in turn to the plate hinged at the other end of the profile, constituting a set of connecting rods, of which there is one that in its middle part carries a powerful spiral spring attached to the profile, to facilitate the opening of the sommier, finally arranging this first section of a transverse plate with its bent ends that acts as a support when the sommier is folded.
