Operating Instructions and Adjustments

The SIHOO B100 Pro chair offers multiple adjustment points to customize your seating experience for maximum ergonomic benefit. Adjust your chair from bottom to top for optimal posture.

Seat Height Adjustment

To adjust the seat height, pull the lever located under the right side of the seat upwards. While pulling the lever, stand up to raise the seat or remain seated to lower it. Release the lever to lock the height in place. Ensure your feet are flat on the floor and thighs are parallel to the ground at a 90-degree angle.

Seat Depth Adjustment

To adjust the seat depth, locate the lever under the left side of the seat. Pull the lever and slide the seat forward or backward until there is a 2-3 finger gap between the front edge of the seat and the back of your knees. Release the lever to lock the position.

Backrest Recline and Tilt Lock

The chair features a 133° maximum recline with a three-position lock. To recline, pull the lever on the left side of the seat upwards and lean back. Release the lever to lock the backrest at your desired angle. The synchronized tilt mechanism allows for a 25° backrest tilt and a 14° seat tilt, ensuring stability without slipping.

Recline Tension Adjustment

Adjust the recline tension by rotating the knob located under the front of the seat. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline). This allows you to customize the resistance based on your body weight.

Lumbar Support Adjustment

The 4D dynamic lumbar support adapts to your movements. The 3-layer ergonomic support structure provides genuine support to the lumbar vertebrae and pelvic area, maintaining the natural S-curve of your spine. Adjust the intensity or position of the lumbar support by rotating the knob on the side of the backrest or by sliding the lumbar pad up or down, if applicable to your model.

Armrest Adjustment

The 4D adjustable armrests offer versatile positioning. They can be folded up 90°, tilted 45mm forward/backward, rotated 360°, and adjusted vertically. Use the buttons or levers on the armrests to make these adjustments. Ensure your shoulders are relaxed and elbows are at a 90-degree angle with forearms supported.

Headrest Adjustment

The 3D oversized headrest can be adjusted vertically by 10 cm and tilted 45° forward/backward to provide optimal neck alignment. Adjust the headrest so it supports the natural curve of your neck, keeping your eyes level with your screen.

Maintenance

Proper maintenance ensures the longevity and performance of your SIHOO B100 Pro chair.

• Cleaning Mesh Fabric: Use a soft brush or vacuum cleaner to remove dust and debris from the mesh. For stains, gently wipe with a damp cloth and mild soap solution. Avoid harsh chemicals or abrasive cleaners.
• Cleaning Frame and Base: Wipe down plastic and metal components with a soft, damp cloth. Dry immediately to prevent water spots.
• Caster Care: Periodically check casters for accumulated hair or debris and clean as needed to ensure smooth movement.
• Tighten Fasteners: Every few months, check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability.

Troubleshooting

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

• Chair Squeaks: Check all bolted connections and tighten any loose screws. Applying a small amount of silicone lubricant to moving parts (e.g., gas lift, tilt mechanism) can also help.
• Gas Lift Not Adjusting: Ensure the height adjustment lever is fully engaged or disengaged. If the issue persists, the gas lift cylinder may need replacement.
• Chair Feels Unstable: Verify that all assembly screws are securely tightened, especially those connecting the base and backrest. Ensure the casters are properly inserted.
• Difficulty with Adjustments: Review the operating instructions to ensure you are using the correct levers and knobs for each adjustment. If a mechanism feels stuck, do not force it; check for obstructions.

If these steps do not resolve the issue, please contact SIHOO customer support for further assistance.
