Extendable furniture device, of the type that is constituted by an axis coaxially coupled to a tubular body, capable of axial and rotary displacement recovered by an intermediate helical spring; essentially characterized in that the shaft it comprises has an eccentric neck that passes eccentrically through a die, so that the helical spring, while acting as a recuperator of axial displacement of the shaft, keeps it twisted in such a way that the eccentric die acts as a brake on the walls of the tube, releasing this block the torsion of the shaft overcoming the tension of the spring by means of a conventional lever.
