- Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, flat surface. Verify all parts are present according to the package contents list.
- Attach Casters to Star Base: Insert each of the five casters (wheels) into the holes at the end of each leg of the star base. Push firmly until they click into place.
- Insert Gas Lift: Place the gas lift cylinder into the central hole of the assembled star base.
- Attach Armrests to Backrest: Align the armrests with the pre-drilled holes on the backrest. Insert the screws but do not fully tighten them yet. This allows for minor adjustments during the next steps.
- Attach Backrest/Armrests to Seat: Position the assembled backrest and armrests onto the seat. Align the holes and insert the screws. Again, do not fully tighten at this stage.
- Attach Mechanism to Seat: Secure the seat mechanism to the underside of the seat using the provided screws. Ensure the front of the mechanism faces the front of the seat. Once all screws are in place for the armrests, backrest, and mechanism, tighten all screws securely.
- Place Assembled Seat onto Gas Lift: Carefully place the assembled seat (with armrests and mechanism attached) onto the top of the gas lift cylinder. The chair is now assembled.

Maintenance
To maintain the longevity and appearance of your office chair:
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
- Avoid Overloading: Do not exceed the maximum weight recommendation of 300 pounds.
Troubleshooting
If you encounter any issues with your chair, consider the following common solutions:
- Chair feels wobbly: Ensure all assembly screws are fully tightened. Check that the gas lift is properly seated in the base.
- Height adjustment not working: Verify the lever is fully engaged or disengaged. Ensure no obstructions are preventing the gas lift from moving freely.
- Casters not rolling smoothly: Check for any debris or hair caught in the wheels. Clean as needed.
