4. Operating Instructions
Your CLATINA Ergonomic Mesh Office Chair EDA offers several adjustments to customize your seating experience.
- Seat Height Adjustment: To raise the seat, lift the lever located under the right side of the seat while taking your weight off the chair. To lower the seat, lift the lever while seated. The chair can be adjusted by approximately 4.7 inches.
- Back Tilt Tension Adjustment: The knob located under the front of the seat controls the tension of the backrest tilt. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
- Adjustable Lumbar Support: The lumbar support is integrated into the backrest and can be adjusted vertically by approximately 1.2 inches to provide optimal support for your lower back. Gently push or pull the lumbar support area to position it.
- Flip-Up Armrests: The armrests can be flipped up 90 degrees. This feature allows the chair to be pushed further under a desk, saving space, and provides flexibility for different tasks.
- 360-Degree Swivel: The chair's base allows for full 360-degree rotation, providing ease of movement and access to your workspace.

5. Maintenance
Proper maintenance ensures the longevity and performance of your office chair.
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners, which can damage the mesh or fabric.
- Inspection: Periodically check all screws and fasteners to ensure they are tight. Retighten if necessary.
- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
6. Troubleshooting
If you encounter issues with your chair, refer to the following common solutions:
- Chair Sinks or Does Not Hold Height: This typically indicates an issue with the gas lift. Ensure the height adjustment lever is not stuck in the 'up' position. If the problem persists, the gas lift may need replacement.
- Chair Squeaks: Check all bolted connections and tighten any loose screws. A small amount of lubricant applied to moving parts (e.g., the mechanism under the seat) can also resolve squeaking.
- Difficulty Rolling: Remove any hair or debris from the casters. Ensure the chair is used on an appropriate surface (hard floor recommended).
- Backrest Does Not Tilt or Tilts Too Easily/Stiffly: Adjust the back tilt tension knob under the seat. Turn clockwise to increase resistance, counter-clockwise to decrease.
