Assembly Instructions
Assembly is quick and easy, typically taking less than 15 minutes for one person.
- Attach Wheels to Star Base: Insert each of the 5 wheels firmly into the holes on the star base until they click into place.
- Insert Gas Lift: Place the decorative cover over the center hole of the assembled star base. Insert the power gas lift into the center hole of the star base.
- Attach Seat to Gas Lift: Carefully align the mechanism on the underside of the seat with the top of the gas lift. Press down firmly until the seat is securely attached. Ensure the "FRONT" label on the mechanism faces forward.
- Attach Backrest: Align the backrest with the designated slots on the seat base and secure with the provided bolts using the included wrench.
Operating Instructions
- Height Adjustment: To adjust the chair height, pull the lever located under the seat upwards while applying or releasing weight from the seat. Release the lever at the desired height.
- Armrest Adjustment (5-Gear): The armrests feature a 5-gear adjustable mechanism. Gently push the armrest inwards towards the seat to disengage the lock, then move it to the desired position (e.g., fully upright, angled, or completely flat). Release to lock into place. This allows for cross-legged sitting or creating space for pets.
- Rocking Function & Tension: The chair supports a rocking function. Use the lever under the seat to enable/disable rocking. A resistance knob is also available to adjust the tension of the rocking motion.
- 360° Swivel & Wheels: The chair features a smooth 360° swivel and durable wheels for easy movement across various floor types, including carpet and hard floors.

Maintenance

Troubleshooting
If you encounter any issues, please refer to the following common solutions:
- Chair not adjusting height: Ensure the gas lift lever is fully engaged and that there is no obstruction. If the issue persists, contact customer support.
- Armrests not locking: Ensure the armrest is pushed inwards completely before attempting to position it. If it still doesn't lock, check for any obstructions in the gear mechanism.
- Squeaking/Noises: Check and tighten all assembly bolts. Lubricate moving parts if necessary.
