5.2. Backrest Recline and Rocking Motion
The chair supports a 90-120 degree rocking motion. To engage or disengage the rocking function, use the tilt lock knob located under the seat. Turn the knob to adjust the tension of the rocking motion. To recline, lean back gently. The chair will rock within its adjustable range.

The headrest can be adjusted for height and angle. To adjust the height, slide the headrest up or down. To adjust the angle, tilt the headrest forward or backward to find your preferred position.
