Framework for supports of armchairs, of anatomical conformation, essentially characterized by being constituted by a frame of suitable conformation, whose lateral vertical edges have an inward curvature, both curvatures being of the same gradual value and of symmetrically opposite disposition and parallel to each other, having provided, approximately one third of the height of the frame, the arrangement in the transverse direction with respect to the vertical axis of the backrest, of a strap of suitable material, the ends of which are joined to the internal faces of the lateral curvatures, in such a way that the assembly is covered by the flexible material covered with upholstery that constitutes the backrest, an anatomical curvature is constituted to support the back of the user, preventing at the same time the deformability by the tension of the expected strap.
