Improvements introduced in the manufacture of somers for folding beds, intended to be collected in the lower part of a seat furniture or in another appropriate receptacle and to be extended towards the front part thereof, characterized by the arrangement of a mesh stretched between two articulated beams and an indeterminate number of crossbeams, being supported by its previous part in two points on said piece of furniture or receptacle and by its later part in two others on the ground endowing it with a certain number of articulated bars to guide the trajectory of its diverse elements between the folding and unfolding positions.
