Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair is wobbly or unstable | Loose screws or improper assembly. | Check all assembly screws and tighten them securely. Ensure the gas lift is fully seated in the base and mechanism. |
| Seat height does not adjust | Gas lift cylinder malfunction or lever issue. | Ensure the height adjustment lever is fully engaged. If the gas lift is faulty, contact customer support for a replacement. |
| Chair does not rock or recline | Recline lock engaged or tilt tension too tight. | Pull the recline lock lever outwards to enable rocking. Loosen the tilt tension knob by rotating it counter-clockwise. |
