4.2 Adjusting Recline and Tilt Tension

• Recline Function (90°-120°): Push the same lever used for height adjustment inwards to lock the backrest in an upright position (90° work mode). Pull the lever outwards to unlock the recline function, allowing the backrest to tilt back (up to 120° rest/sleep mode).
• Tilt Tension: Rotate the round knob located under the front-center of the seat. Turn clockwise to increase tilt tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).

• Angle Adjustment: Rotate the headrest forward or backward (up to 90°) to find the optimal angle for neck support.

4.4 Adjusting Lumbar Support

4.5 Using Flip-Up Armrests

• To flip up the armrests: Gently lift the armrests upwards until they lock into a vertical position. This allows the chair to be pushed closer to a desk or stored more compactly.
• To lower the armrests: Pull the armrests downwards until they return to their horizontal position.
