Operating Instructions
Your OLIXIS Office Desk Chair offers several adjustable features for personalized comfort:
- Height Adjustment: To adjust the seat height, pull the lever located under the right side of the seat upwards. While holding the lever, stand up to raise the chair or sit down to lower it. Release the lever at your desired height. The height is adjustable from 14.7 inches to 17.7 inches.
- Rocking Mode: To engage the rocking function, pull the same lever (used for height adjustment) outwards. To lock the chair in an upright position, push the lever inwards. The chair allows for a 90°-120° tilt.
- Tilt Tension Control: The round knob located under the front-center of the seat controls the tension of the rocking mode. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).
- 360° Swivel and Casters: The chair features a 360° swivel function and smooth-rolling casters for easy movement around your workspace. The casters are designed to be quiet and prevent scratches on floors.

Maintenance
Proper care will extend the life of your OLIXIS Office Desk Chair:
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Regular Checks: Periodically check all screws and bolts to ensure they are tight. Re-tighten as necessary.
- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
- Avoid Overloading: Do not exceed the maximum weight capacity of 250 pounds.
Troubleshooting
If you encounter issues with your chair, refer to the following common solutions:
- Chair Sinks or Won't Stay Up:
Solution: The gas lift cylinder may be faulty. Contact customer support for a replacement.
- Chair Wobbles:
Solution: Check all screws, especially those connecting the mechanism plate to the seat and the armrests to the backrest/seat. Tighten any loose screws. Ensure the gas lift is fully inserted into the base.
- Casters Don't Roll Smoothly:
Solution: Remove any hair, dust, or debris from the caster wheels. If they are still stiff, they may need lubrication or replacement.
- Difficulty with Rocking Mode:
Solution: Ensure the rocking lever is pulled outwards to enable the function. Adjust the tilt tension knob to your preference.
