Always use the chair within the recommended weight limit of 300 pounds. Be cautious when adjusting the chair or using the footrest to prevent tripping. Keep the chair on a stable surface and away from heat sources.

3. Product Features

• Adaptive Dynamic Lumbar Support: Equipped with an elastic adaptive dynamic lumbar pillow and dual-back design. This system helps maintain the natural spinal S-curve, potentially reducing back strain and fatigue. The lumbar support adapts to body movements.
• Fully Adjustable for a Customized Fit: Offers 3 adjustable recline angles (110° for focused work, 123° for relaxed meetings, and 135° for stress-relief breaks). The 2D extra-wide headrest provides expanded support and may alleviate neck tension. Flip-up armrests allow the chair to slide under desks and reduce shoulder strain.
• Breathable & Pressure-Relieving Design: Full-mesh construction promotes airflow to prevent overheating. The pressure-relief cushion distributes weight evenly to reduce sitting pressure.
• Sturdy & Quiet Construction: Features a reinforced frame and heavy-duty base, supporting up to 300 lbs. Premium quality silent tilt with noise-dampening design allows quiet adjustments.

4. Setup and Assembly

The SIHOO B100 Ergonomic Office Chair requires assembly. All necessary components, including casters, chair parts, and instructions, are included in the packaging.

Please follow the detailed diagrams and instructions provided in the box. For additional guidance, an assembly video may be available on the official SIHOO website. Ensure all connections are secure before using the chair.

5. Operating Instructions (Adjustments)

To maximize comfort and ergonomic benefits, properly adjust your SIHOO B100 chair. Adjustments should generally be made from bottom to top.

• Seat Height: Adjust the seat height so your feet are flat on the floor and your thighs are parallel to the ground, with your knees at approximately a 90-degree angle.
• Seat Depth: Ensure there is a 2-3 finger gap between the front edge of the seat and the back of your knees. This ensures proper thigh support without restricting circulation.
• Lumbar Support: The adaptive dynamic lumbar support is designed to conform to your lower back, maintaining the natural S-shape of your spine. It should firmly press against your lower back.
• Backrest Recline: Utilize the recline function to find comfortable working or resting positions. The chair offers 110° for focused work, 123° for relaxed meetings, and 135° for breaks. Adjust the recline tension for comfortable, supportive resistance.
• Armrests: The flip-up armrests can be moved out of the way when not needed. When in use, adjust them so your shoulders are relaxed and your elbows are at approximately a 90-degree angle, with forearms supported.
• Headrest: Adjust the headrest to support the middle curve of your neck. Your eyes should be level with your screen when seated upright. The 2D headrest offers expanded support and can be adjusted for multiple positions (4" lift, 45° rotation).

6. Maintenance

Regular maintenance helps prolong the life and performance of your SIHOO B100 chair.

• Cleaning: For the mesh material, gently wipe with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners. For the polypropylene frame, use a soft cloth with a gentle cleaning solution.
• Casters: Periodically check the casters for hair or debris that may impede smooth movement. Clean as necessary.
• Fasteners: Occasionally check all screws and bolts to ensure they are tight. Retighten if any feel loose.
• Weight Limit: Do not exceed the maximum weight recommendation of 300 pounds.

7. Troubleshooting

If you encounter issues with your SIHOO B100 chair, refer to the following common solutions:

• Chair Squeaks: Check all bolted connections and tighten them. A small amount of silicone spray lubricant can be applied to moving parts if the squeaking persists, avoiding contact with mesh or fabric.
• Difficulty Adjusting Height: Ensure the height adjustment lever is fully engaged. Check for any obstructions under the seat or around the gas lift cylinder.
• Chair Does Not Recline: Verify that the recline lock is disengaged. Adjust the recline tension knob to a lighter setting if it feels too stiff.
• Unstable Chair: Ensure the chair is on a flat, even surface. Check that all casters are properly installed and functioning. Verify that the base is securely attached to the gas lift.
