Folding frame for sofas, which are of the type that are constituted by three sections articulated with each other and in which the central and the foot includes legs in "U" each driven by two connecting rods together and with the intermediate piece of articulation between sections, the end of one of them being related to the previous section, essentially characterized because the first section has each of its sides articulated to the ends of two arched decks, one greater than the other and with their connections faced and joined by a recovery spring, the other ends being articulated in respective emerging plates of an "L" profile, the lower plate also having at its lower end a lug that runs along the rounded periphery of its corresponding plate and is liable to fit in a notch of it; forming the "L" profiles of each side jointly with a connecting beam and some studs, the base of the whole.
