- Attach Casters to Base: Insert the five casters 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 center hole of the star base. Ensure it is seated securely.
- Place Gas Lift Cover: Slide the gas lift cover over the gas lift cylinder.
- Attach Mechanism to Seat: Align the chair mechanism (usually pre-attached to the seat or needs to be screwed on) with the screw holes on the underside of the seat cushion. Secure with the provided screws and Allen key. Ensure the front of the mechanism faces the front of the seat.
- Connect Seat to Gas Lift: Carefully place the assembled seat (with mechanism) onto the gas lift cylinder. The tapered end of the gas lift should fit into the center hole of the mechanism. Press down firmly to secure.
Once assembled, test the chair's stability and functionality before regular use.
6. Operating Instructions
6.1. Seat Height Adjustment
The chair features a pneumatic gas lift for easy height adjustment. To adjust the seat height:
- To raise the seat: Lift the lever located under the seat (usually on the right side) while taking your weight off the seat. The seat will rise automatically. Release the lever at the desired height.
- To lower the seat: Lift the lever while remaining seated. The seat will lower under your weight. Release the lever at the desired height.
6.2. Rocking Function
The chair is equipped with a rocking function for relaxation and stretching. To use the rocking function:
- To enable rocking: Pull out the lever (often the same lever used for height adjustment, or a separate one) to unlock the rocking mechanism.
- To disable/lock rocking: Push the lever in to lock the chair in an upright position.
- Adjusting Tilt Tension: A round knob located under the seat (usually at the front) controls the tension of the rocking mechanism. Turn clockwise to increase tension (making it harder to rock) or counter-clockwise to decrease tension (making it easier to rock).
6.3. 360-Degree Swivel
The chair's casters and central mechanism allow for full 360-degree rotation and easy mobility. Simply push off the floor with your feet to move the chair or rotate as needed.
7. Maintenance
7.1. Cleaning
- Fabric (Velvet Touch Polyester): Gently vacuum the fabric regularly to remove dust and debris. For spills, blot immediately with a clean, dry cloth. For stubborn stains, use a mild fabric cleaner and test on an inconspicuous area first. Do not rub vigorously.
- Metal Parts: Wipe metal components with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Casters: Periodically clean the casters to remove hair, dust, and debris that can impede smooth rolling.
7.2. General Care
- Regularly check all screws and bolts and tighten them as needed to maintain stability.
- Avoid exposing the chair to extreme temperatures or humidity.
- Do not use the chair as a step stool or ladder.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair is wobbly/unstable | Loose screws or bolts | Check and tighten all assembly screws and bolts. |
| Seat does not adjust height | Gas lift not properly engaged or faulty | Ensure the gas lift lever is fully engaged. If still not working, the gas lift may need replacement. |
| Casters not rolling smoothly | Debris (hair, dust) caught in casters | Turn the chair over and clean any debris from the caster wheels. |
| Chair makes squeaking noises | Loose connections or friction between parts | Tighten all screws. Apply a small amount of silicone lubricant to moving parts if necessary. |
| Rocking function is too stiff/loose | Tilt tension not adjusted correctly | Adjust the tilt tension knob under the seat (clockwise for stiffer, counter-clockwise for looser). |
9. User Tips
- For optimal comfort, adjust the seat height so your feet are flat on the floor and your knees are at a 90-degree angle.
- Utilize the rocking function for short breaks to stretch your back and improve circulation during long periods of sitting.
- Consider using a chair mat if placing the chair on carpeted surfaces to ensure smooth rolling of the casters.
