- 360° Swivel: The chair features a 360° swivel function, allowing for easy rotation without moving the base.
- Rolling Casters: The silent swivel casters allow for smooth movement across various surfaces, including hard floors, carpet, and tile.



Maintenance
Proper maintenance will extend the life and appearance of your ERGOSEAT chair.
- Cleaning: Wipe clean with a damp cloth. For tougher stains on the PU leather, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Hardware Check: Periodically check all screws and bolts to ensure they remain tight. Re-tighten as necessary to maintain stability.
- Caster Care: Keep the wheels free of debris (hair, dust) to ensure smooth rolling.
Troubleshooting
If you encounter issues with your chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair is unstable or wobbly. | Loose screws or incorrect assembly. | Check all assembly points and tighten screws. Ensure the gas lift is fully seated in the base. |
| Height adjustment not working. | Gas lift malfunction or lever not engaged. | Ensure the lever is pulled completely. If the issue persists, the gas lift may need replacement. |
| Wheels do not roll smoothly or make noise. | Debris in casters or damaged wheels. | Clean any hair or debris from the wheel casters. If wheels are damaged, consider replacement. |
| Squeaking noises during use. | Loose connections or friction between parts. | Tighten all screws. Apply a small amount of silicone lubricant to moving parts if necessary, avoiding contact with upholstery. |
