3. Assembly Instructions

Follow these steps carefully to assemble your office chair.

1. Attach Casters to Star Base: Insert each caster (F) into the holes at the end of each leg of the star base (E). Push firmly until they click into place.
2. Insert Gas Lift: Place the gas lift cylinder (D) into the center hole of the assembled star base (E). Ensure it sits securely.
3. Attach Mechanism Plate to Seat: Align the mechanism plate (G) with the pre-drilled holes on the underside of the seat cushion (B). Ensure the front of the mechanism plate faces the front of the seat. Secure with four M8x25mm screws (I) using the Allen wrench (J).
4. Attach Armrests to Seat: Attach the armrests (C) to the underside of the seat cushion (B) using four M6x20mm screws (H), two per armrest. Do not fully tighten yet.
5. Attach Chair Back to Armrests: Align the chair back (A) with the remaining holes on the armrests (C). Secure with the remaining four M6x20mm screws (H), two per armrest. Now, fully tighten all armrest screws.
6. Connect Seat Assembly to Gas Lift: Carefully place the assembled seat and back onto the gas lift cylinder (D) protruding from the star base. Press down firmly to secure.

Your office chair is now assembled.

4. Operating Instructions

Familiarize yourself with the chair's adjustment features for optimal comfort.

• Height Adjustment: To raise the seat, lift the lever located under the right side of the seat while taking your weight off the chair. To lower the seat, lift the lever while seated. Release the lever at the desired height.
• Tilt Lock/Unlock: Pull the same lever outwards to unlock the tilt function, allowing the chair back to recline. Push the lever inwards to lock the chair back in an upright position.
• Tilt Tension: Rotate the round knob located under the front-center of the seat to adjust the tension of the tilt mechanism. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
• Armrest Adjustment (if applicable): Some models feature adjustable armrests. Look for buttons or levers on the armrests to adjust their height or pivot.

5. Maintenance

Regular maintenance will prolong the life of your office chair.

• Cleaning: Wipe surfaces with a soft, damp cloth. For fabric upholstery, use a mild fabric cleaner. Avoid harsh chemicals or abrasive cleaners.
• Fastener Check: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
• Caster Cleaning: Remove any hair or debris that may accumulate around the casters to ensure smooth movement.
• Lubrication: The gas lift cylinder is maintenance-free. Do not attempt to lubricate it.
