Chair whose upper plate is supported on the support plate by means of compression rear springs, the upper plate having at its front end a lower rod guided through a hole of the support plate is provided with a lower nut acting on a helical spring threaded on the stem itself and applied under the upper plate to soften the pressure of the aforementioned rear springs and allow adequate oscillation of said upper carrier plate of the seat.
