Operating Instructions
Your BestOffice Ergonomic Office Chair offers several adjustable features to customize your seating experience for maximum comfort and support.
Adjustable Height:
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever upwards to lower the seat. To raise the seat, lift your weight off the chair and pull the lever upwards. Release the lever at your desired height to lock it in place. The seat height is adjustable from 17.1 inches to 20.3 inches.
Tilt and Recline Function:
The chair features a tilt mechanism allowing for a comfortable recline. To enable tilting, pull the same lever (used for height adjustment) outwards. To lock the chair in an upright position, push the lever inwards. The chair can recline up to 125 degrees.
Tension Control:
Adjust the recline tension by turning the round knob located underneath the front of the seat. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).

Maintenance
Proper care and maintenance will extend the life of your BestOffice Ergonomic Office Chair.
- Cleaning: Wipe clean with a damp cloth. For stubborn stains, use a mild soap solution and a soft cloth, then wipe dry. Avoid harsh chemicals or abrasive cleaners.
- Regular Checks: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
- Caster Care: Keep the casters free of debris (hair, dust, etc.) to ensure smooth rolling.
- Weight Capacity: Do not exceed the maximum weight capacity of 250 lbs (113 kg) to prevent damage and ensure safety.
Troubleshooting
If you encounter any issues with your chair, please refer to the following common solutions:
- Chair Sinks or Won't Stay Up: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift cylinder may need replacement.
- Difficulty Rolling: Check casters for trapped debris (hair, lint) and clean them thoroughly. Ensure the chair is used on an appropriate surface.
- Squeaking Noises: Tighten all assembly screws. A small amount of lubricant can be applied to moving parts if necessary.
- Unstable or Wobbly: Verify that all screws are securely tightened and that the chair base is properly assembled.
