- Insert Gas Lift: Place the gas lift cylinder into the central hole of the assembled base. Ensure it sits securely.
- Attach Mechanism Plate to Seat: Align the mechanism plate with the pre-drilled holes on the underside of the seat cushion. Secure it using the provided screws. Ensure the lever for height adjustment faces the front of the seat.
- Attach Armrests to Seat: Secure the armrests to the sides of the seat cushion using the designated screws. Do not overtighten initially.

4. Operating Instructions
This section details how to use the various adjustable features of your chair.
- Height Adjustment: To raise the seat, lift the lever located on 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 Mechanism: The chair features a tilt mechanism. Pull the lever outwards to unlock the tilt function, allowing the chair to rock. Push the lever inwards to lock the chair in an upright position.
- Tilt Tension Adjustment: A round knob located under the front of the seat allows you to adjust the tension of the tilt mechanism. Turn clockwise to increase tension (requiring more force to recline) and counter-clockwise to decrease tension (allowing easier recline).
- 360° Swivel: The chair is designed to swivel 360 degrees for ease of movement and access.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your chair.
- Cleaning: The synthetic leather upholstery is easy to clean. Wipe with a damp cloth and mild soap solution. Avoid harsh chemicals or abrasive cleaners, which can damage the material.
- Fastener Check: Periodically (e.g., every 3-6 months) check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability and safety.
- Wheel Cleaning: Remove any hair or debris that may accumulate around the wheels to ensure smooth rolling.
- Gas Lift: The gas lift is a sealed unit and requires no maintenance. If it fails to function, contact customer support for replacement.
