6. Troubleshooting
If you encounter any issues with your Dowinx Criss Cross Chair, please refer to the following common solutions:
- Chair not adjusting height: Ensure the height adjustment lever is fully engaged and the gas lift is not obstructed. If the issue persists, the gas lift may need replacement.
- Squeaking or wobbling: Check all assembly screws and bolts. Tighten any loose connections. Applying a small amount of lubricant to moving parts (e.g., casters, gas lift mechanism) can also help.
