5. Maintenance
5.1. Upholstery Care (Velvet)
- Regularly vacuum the velvet upholstery using a soft brush attachment to remove dust and debris.
- For spills, blot immediately with a clean, dry cloth. Do not rub.
- For stubborn stains, use a mild upholstery cleaner and test on an inconspicuous area first.
- Avoid direct sunlight to prevent fading.
5.2. Metal Parts Care
- Wipe chrome metal parts with a soft, damp cloth. Dry immediately to prevent water spots.
- Avoid abrasive cleaners or harsh chemicals that could damage the finish.
5.3. General Maintenance
- Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Keep casters clean from hair and debris to ensure smooth rolling.
6. Troubleshooting
6.1. Chair Sinks or Does Not Hold Height
If the chair's height adjustment mechanism (gas lift) fails to hold its position, the gas lift cylinder may be defective. This component is typically sealed and not user-serviceable. Contact Vente-unique customer support for assistance.
6.2. Casters Not Rolling Smoothly
Check the casters for accumulated hair, dust, or debris. Clean them thoroughly. If the issue persists, ensure the casters are properly inserted into the base.
6.3. Chair Squeaks
Squeaking often indicates loose connections. Check and tighten all assembly screws. A small amount of silicone-based lubricant can be applied to moving parts if necessary, avoiding contact with upholstery.
