- Install the Gas Lift: Place the gas lift cylinder into the central hole of the assembled 5-star base.
- Attach the Mechanism Plate: Secure the mechanism plate to the underside of the seat cushion using the provided screws. Ensure the front of the mechanism faces the front of the seat.
- Connect Armrests to Backrest: Attach the armrests to the backrest using the designated screws.
- Attach Backrest/Armrest Assembly to Seat: Align the backrest and armrest assembly with the pre-drilled holes on the seat cushion and secure with screws.

Operating Instructions
Height Adjustment:
To adjust the chair's height, locate the lever on the right side, beneath the seat. While seated, pull the lever up to lower the chair. To raise the chair, stand up and pull the lever up. Release the lever at your desired height to lock it in place.
Tilt Function (Rocking Style):
The chair features a 90°-120° tilt tension for comfortable reclining. To activate the tilt, pull out the adjustment lever located on the left side, beneath the seat. To lock the chair in an upright position, push the lever back in. The tilt tension knob, located at the front of the mechanism, can be rotated to adjust the resistance of the recline.

Flip-Up Armrests:
The padded armrests can be flipped up 90° to save space or allow the chair to be pushed closer to a desk. Simply lift the armrests upwards until they lock into the vertical position. To return them to the horizontal position, gently pull them down.

- Casters: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling. Clean regularly.
- Gas Lift: Do not attempt to disassemble the gas lift cylinder. If it malfunctions, contact customer support.
