Operating Instructions

1. Dynamic 3-Zone Lumbar Support

The chair features a dynamic 3-zone lumbar support system that adapts to your posture. The lateral wings pivot (40°-80°) to support your back, and the 60mm vertical adjustment targets the L1-L5 vertebrae. This system provides continuous support whether you are leaning forward or reclining.

Note on Lumbar Adjustment: The lumbar support uses a cyclic ratchet mechanism. To lower it from a middle position, first raise it to its highest point to unlock the mechanism, then push it all the way down. This is a normal design feature.

2. Upgraded 4D Dual-Axis Headrest

The headrest offers precise adjustments: 70mm depth, 40mm height, and 70° rotation. This allows for zero-pressure neck support and helps maintain proper body alignment to reduce shoulder and neck fatigue.

3. Adaptive Recline (Up to 140°)

The chair features a gravity-sensing mechanism that automatically adjusts tilt tension based on your body weight. It offers four distinct recline positions:

• 105° Deep Focus: Ideal for concentrated work.
• 115° Relaxed Workflow: Suitable for general tasks and thinking.
• 130° Natural Ease: For relaxing breaks.
• 140° Resting: For extended relaxation or napping.

4. 720° Omnifunctional Armrests

The armrests offer dual 360° rotation and 39° folding, providing comprehensive support for your elbows in various arm positions. They can be adjusted up and down, front and back, and folded for convenience.

5. Seat Depth Adjustment

Adjust the seat depth by up to 50mm to accommodate different leg lengths and ensure proper thigh support, preventing pressure points.

6. Backrest Height Adjustment

The backrest can be adjusted vertically by 80mm to suit users of various heights, ensuring optimal back support.

Note on Backrest Adjustment: Similar to the lumbar support, the backrest height adjustment uses a cyclic ratchet mechanism. To lower it from a middle position, first raise it to its highest point to unlock the mechanism, then push it all the way down. This is a normal design feature.

7. Footrest (if applicable)

If your model includes a footrest, it can be extended for additional leg support during reclining. Pull the footrest out from under the seat and adjust to your desired position. Retract it by pushing it back under the seat when not in use.

Maintenance

• Cleaning Mesh Fabric: Use a soft brush or vacuum cleaner to remove dust and debris. For stains, gently wipe with a damp cloth and mild soap solution. Avoid harsh chemicals.
• Cleaning Frame: Wipe the polypropylene frame with a soft, damp cloth.
• Casters: Periodically check casters for hair or debris and clean as needed to ensure smooth movement.
• Moving Parts: Ensure all adjustment mechanisms operate smoothly. Do not force adjustments.
• General Inspection: Regularly inspect all screws and bolts to ensure they are tight. Retighten if necessary.

Troubleshooting

Issue: Backrest or Lumbar Support does not lower from a middle position.

Solution: The backrest and lumbar support use a cyclic ratchet mechanism. To lower, first raise the component to its highest point to unlock the mechanism, then push it all the way down. This is a normal design feature, not a defect.

Issue: Armrests feel wobbly or move too freely.

Solution: While the 720° armrests are designed for extensive movement, ensure all assembly screws are securely tightened. If the issue persists, contact customer support.

Issue: Footrest does not stay retracted or extends unintentionally.

Solution: Check if there is any obstruction preventing the footrest from fully retracting. Ensure the locking mechanism (if present) is engaged. If the issue continues, contact customer support.

Issue: Chair makes squeaking noises.

Solution: Check and tighten all assembly bolts and screws. A small amount of silicone lubricant can be applied to moving metal parts if the noise persists, avoiding contact with plastic or mesh components.
