A shock absorber between moving parts in a piece of furniture comprises an elongated holding body (23) provided with an axial cavity, at the inside of which a piston element (25) and a rod (22) slide, the holding body and rod acting on one of the two moving parts of the piece of furniture respectively, a first spring (28) being present between the rod and piston element and a second spring (29) being present between the piston element and a bottom of the holding body, the piston element having a circumferential portion (26) of friction with the inner wall of the holding body, the portion of the piston element close to the friction portion forming a wedging seat (31) provided with longitudinal discontinuities (33) to enable elastic expansion when the seat receives a wedge end (27) of the rod in a wedge engagement.
