5.4. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up slightly and pull the lever up. Release the lever to lock the height.
5.5. Tilt Lock and Tension Adjustment
The chair features a 4-position tilt lock. Use the lever on the left side beneath the seat to lock the backrest at various angles (e.g., 90°, 105°, 120°, 130°). The tilt tension knob, typically located at the front center or right side beneath the seat, controls the resistance when reclining. Turn clockwise to increase tension, counter-clockwise to decrease.

To adjust the seat depth, locate the knob on the left side beneath the seat. Pull the knob to unlock the seat, then slide the seat forward or backward to achieve the desired depth. Release the knob to lock the seat in position. This feature helps ensure proper thigh support and reduces pressure behind the knees.

7. Troubleshooting
If you encounter issues with your chair, consider the following common solutions:

- Casters not rolling smoothly: Clean any hair or debris from the caster wheels.
- Gas lift not holding height: If the chair slowly sinks, the gas lift may need replacement. Contact customer support.
