Important Safety Information
Warning: To prevent injury and damage to the chair, observe the following safety guidelines:
- Do not exceed the specified weight limit of 149.69 kg (330 lbs). Exceeding this limit can lead to overload and potential damage to the chair.
- Do not lean back excessively to the point where the front legs lift off the floor, as this may cause the chair to tip over.
- Avoid leaning too far forward, as this can also lead to instability and tilting.
- Ensure all components are securely fastened before use. Periodically check and tighten all screws.

Operating and Adjustments
The CLOUVOU BrightSeat chair offers multiple adjustment options to customize your seating experience for optimal comfort and ergonomic support.
1. Seat Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up slightly and pull the lever up. Release the lever at the desired height to lock it in place.
2. Backrest Tilt and Lock
The backrest can be tilted and locked at various angles, up to 135 degrees. Use the lever on the left side beneath the seat to unlock the tilt mechanism. Lean back to your desired angle and push the lever down to lock the backrest in position. To return to an upright position, unlock the lever and lean forward.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your CLOUVOU BrightSeat office chair.
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the material. For mesh fabric, a soft brush can be used to remove dust.
- Fastener Check: Periodically inspect all screws and bolts. Tighten any loose fasteners to maintain stability and prevent squeaks.
- Wheel Care: Keep the Flux Wheels clean from debris such as hair or dust, which can hinder smooth movement. The wheels are designed for quiet operation on various floor types.
