The chair features a 135° tilt-locking function with three lockable positions (90°, 110°, 135°). To engage or disengage the tilt lock, push the same lever used for height adjustment inwards or pull it outwards. To adjust the tilt tension, rotate the round knob located under the front-center of the seat.
