Maintenance
Regular maintenance will help preserve the appearance and extend the lifespan of your VECELO office chair.
- Cleaning Mesh Fabric: The HD dragon-scale mesh is wear-resistant and non-slip. For general cleaning, gently wipe the mesh with a soft, damp cloth using mild soap and water. Avoid abrasive cleaners or harsh chemicals. Allow to air dry completely.
- Cleaning Frame and Base: Wipe down the nylon five-star base, armrests, and other plastic/metal components with a soft, damp cloth.
- Caster Care: The soft PU-wrapped silent universal wheels are designed to be smooth and floor-friendly. Periodically check the casters for any accumulated debris (hair, dust, etc.) and clean them to ensure smooth rolling.
- Hardware Check: Regularly inspect all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain the chair's stability and safety.
Troubleshooting
If you encounter any issues with your VECELO office chair, please refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair squeaks when leaning back. | Loose connections or lack of lubrication in the reclining mechanism. | Check and tighten all bolts connecting the backrest and seat mechanism. Apply a small amount of silicone-based lubricant to moving parts of the tilt mechanism if accessible. |
| Armrests or headrest are difficult to adjust. | Mechanism might be stiff or require proper engagement. | Ensure you are pressing the release buttons fully. Apply gentle force while adjusting. If persistent, check for any obstructions. |
| Footrest feels flimsy or does not extend/retract smoothly. | Misalignment or wear on the sliding mechanism. | Ensure the footrest is properly aligned in its tracks. Clean any debris from the tracks. If the issue persists, inspect the connection points for damage. |
| Chair feels unstable or wobbly. | Loose assembly bolts or damaged base/casters. | Re-tighten all assembly bolts, especially those connecting the seat to the base and the backrest. Inspect the five-star base and casters for any visible damage. |
If these solutions do not resolve the issue, please contact VECELO customer support for further assistance.
