Operating Instructions
Your ergonomic office chair is designed with multiple adjustment features to provide personalized comfort and support. Familiarize yourself with these functions for optimal use:
- Seat Height Adjustment: Use the lever located under the seat to raise or lower the chair to your desired height. Ensure your feet are flat on the floor or on a footrest.
- 2-to-1 Synchro-Tilt: This mechanism allows the seat and backrest to recline in unison at a 2-to-1 ratio, keeping the seat closer to the floor as you recline. Pull the lever outward to activate the rocking motion.
- Tilt Lock: The chair features 3 locking positions to secure your preferred reclined or upright working position. Push the lever inward to lock the tilt.
- Tilt Tension Knob: Adjust the rocking motion resistance by turning the knob located underneath the seat. Turn clockwise for more resistance, counter-clockwise for less.
- Adjustable Headrest: The pivot headrest can be adjusted incrementally for height to support your neck and head.
- Adjustable Pivot Arms: The padded armrests can be adjusted for height and pivot inward and outward to accommodate various tasks and body postures.
- Lumbar Support: The curved backrest provides integrated lumbar support, promoting a healthy spinal posture.

Maintenance and Care
Regular maintenance will extend the life and appearance of your office chair:
- Cleaning: For the mesh fabric, use a vacuum cleaner or a light brush to remove dirt and debris. For deeper cleaning, use a mild soap solution and a damp cloth, then wipe dry. Avoid harsh chemicals.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary.
- Moving Parts: The chair's moving parts are designed for durability. Avoid applying excessive force to adjustment levers or mechanisms.
Troubleshooting
If you encounter any issues with your Flash Furniture LO Ergonomic Mesh Office Chair, please consider the following:
- Chair not adjusting height: Ensure the pneumatic cylinder lever is fully engaged or disengaged as required. Check for any obstructions.
- Chair not reclining or locking: Verify that the tilt lock lever is correctly positioned. Adjust the tilt tension knob if the recline motion is too stiff or too loose.
- Squeaking noises: Check and tighten all assembly bolts and screws. Lubrication may be applied to moving metal parts if necessary.
If problems persist, please contact Flash Furniture customer support for assistance.
