5. Operating Instructions

Familiarize yourself with the various adjustments to customize your seating experience.

Seat Height Adjustment: Locate the lever under the right side of the seat. To raise the seat, lift the lever while taking your weight off the chair. To lower the seat, lift the lever while seated. Release the lever to lock the height. The air rod allows for approximately 10cm of vertical adjustment.
Backrest Rocking Function: The chair features a rocking function with an adjustable range of 90° to 120°. Use the control knob or lever (typically under the seat) to engage or disengage the rocking motion and adjust its tension.
Headrest Adjustment: The headrest can be adjusted vertically by 6cm and tilted by 90° to provide optimal neck and head support. Adjust it to a position that comfortably supports your head and neck.
Folding Armrests: The armrests can be folded up by 90°. This feature allows you to push the chair closer to your desk or save space when not in use. Simply lift the armrests upwards until they lock into the folded position.
Swivel Function: The chair's 360° swivel allows for easy movement and access to different areas of your workspace without needing to reposition the entire chair.

6. Maintenance and Care

Regular maintenance will help prolong the life and appearance of your office chair.

Cleaning Mesh and Fabric: For general cleaning, use a soft brush or vacuum cleaner to remove dust and loose debris. For stains, gently blot with a damp cloth and mild soap solution. Avoid harsh chemicals or abrasive cleaners.
Cleaning Plastic and Metal Parts: Wipe plastic and metal components with a soft, damp cloth. Dry immediately to prevent water spots.
Caster Maintenance: Periodically check the casters for hair or debris that may hinder smooth movement. Clean them as needed.
Tighten Fasteners: Over time, screws and bolts may loosen. Periodically check all fasteners and tighten them to ensure stability and safety.
Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading and material degradation. Position the chair away from direct sunlight when possible.

8. User Tips

Maintain Good Posture: Adjust the chair's height so your feet are flat on the floor or a footrest, and your knees are at a 90-degree angle. Ensure your back is supported by the backrest.
Utilize Adjustments: Take advantage of the adjustable headrest and rocking function to find the most comfortable and supportive position for your body throughout the day.
Take Breaks: Even with an ergonomic chair, it's important to take regular breaks to stand, stretch, and move around to promote circulation and reduce fatigue.
