Chair - 50 GEL. Gas lift works perfectly. Stable. Comfortable. Rolls easily. Tilt position adjusts conveniently. Resistance adjustment. Material on the seat and armrests is cracked. The seat tilt adjustment is broken - the metal tore, so welding is needed. Tried cold welding - didn't work. Without repair, the backward tilt lock does not work. Saburtalo, self-pickup.
