5. Operating Instructions
Your Winrise office chair offers several adjustable features to customize your seating experience:
5.1. Seat Height Adjustment
To adjust the seat height, pull the lever located on the right side of the seat upwards. While holding the lever, stand up to raise the seat or remain seated to lower it. Release the lever at your desired height to lock it in place. The maximum height adjustable range is between 36.9 inches and 40.9 inches.
5.2. Lumbar Support Adjustment
The adjustable lumbar support is designed to protect your spine and relieve back pain. The lumbar support can be adjusted up and down by approximately 1.2 inches to fit the curve of your back.

5.3. Back Rocking Function and Tilt Control
To activate the rocking function, pull out the lever located on the left side of the seat. The chair can swing at a 30-degree angle for comfortable resting. To lock the chair in an upright position, push the lever back in. The tilt tension can be adjusted by rotating the knob located underneath the seat, allowing you to control the resistance of the rocking motion.

7. Troubleshooting
If you encounter any issues with your chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair wobbles or feels unstable | Loose screws or uneven assembly. | Check and tighten all assembly screws. Ensure the chair is on a flat surface. |
| Chair does not adjust height | Gas lift cylinder malfunction or lever not engaged. | Ensure the height adjustment lever is fully pulled. If the issue persists, the gas lift may need replacement. |
| Casters do not roll smoothly | Debris caught in casters or damaged casters. | Clean any hair or debris from the caster wheels. If damaged, casters may need replacement. |
| Backrest does not rock or lock | Rocking lever not engaged or tilt tension too tight. | Pull out the rocking lever to enable rocking. Adjust the tilt tension knob to loosen the resistance. |
| Chair sinks when sitting (gas lift issue) | Gas lift cylinder losing pressure. | This indicates a worn gas lift cylinder. Contact customer support for a replacement if within warranty. |
