• Rotate the adjustment lever located under the seat (towards the back) to raise or lower the seat height.
• To lower the height: sit on the chair while operating the lever.
• To raise the height: stand up while operating the lever.

• Activate recline function: Pull outward the adjustment lever on the right side of the seat (towards the back) to unlock the backrest and enter free-recline mode.
• Angle lock (90°–105°–120°–130°): After pulling the lever out, gently lean back to your preferred angle, then push the lever fully back to its original position to lock. A “click” sound indicates successful locking.
• Unlock recline position: Apply gentle backward pressure with your body to release the lock, then pull the lever out again to readjust the recline angle.
• Recline tension adjustment: If the recline feels too firm or too loose, rotate the tension control knob to adjust the reclining resistance to your preference.

Hold the armrest adjustment lever and lift the armrest to adjust it to the desired height.

• Unlock the cushion: Pull the round adjustment lever (located at the front of the chair) straight upward, and keep it fully lifted during the adjustment.
• Adjust cushion depth: Gently lean back, allowing the mesh elastomer to guide your hips as the cushion moves naturally.
• Adjust forward: While leaning back, gently push your hips forward.
• Adjust backward: Relax the pressure from your hips and let the cushion slide backward naturally.

• Height adjustment: Locate the lumbar support panel, firmly hold both sides of its upper edge with your hands, and slide it evenly up or down to the desired position.
• Support strength adjustment: Find the adjustment knob and rotate it to control the level of support. Turn counterclockwise to increase support strength, and clockwise to reduce it.

Headrest forward/backward adjustment

• Forward adjustment: The headrest can be freely pushed forward from its current position until it reaches the furthest point. Once released, it will automatically lock in place.
• Backward adjustment: A mid-position anti-rebound lock prevents the headrest from being pushed directly backward.

To adjust backward, follow these steps:

• Unlock: Firmly push the headrest forward to its maximum extended position until the locking mechanism is fully released.
• Reset preparation: Slowly pull the headrest backward to its initial (rearmost) position.
• Position adjustment: Push the headrest forward to the desired position.

Multi-dimensional headrest adjustment

• Headrest pivot rotation: Adjusts the overall angle to accommodate users of different heights.
• Headrest rotation: Fine-tunes the neck support area for optimal cervical curve alignment.
