Operating Instructions

Familiarize yourself with the various adjustment features of your SIHOO ergonomic chair to optimize your comfort and support.

1. Reclining Function (up to 135°):

   The chair features a maximum 135° recline. To recline, lean back gently. The smart gravity-sensing base automatically adjusts the rebound force based on your body weight, providing a comfortable recline without manual lever operation for tension adjustment. To lock or unlock the recline, refer to the specific lever instructions in your packaged manual.

2. Retractable Footrest:

   Pull out the footrest located beneath the seat to extend it. This allows you to stretch your legs or take a nap, especially when combined with the reclining function. Push it back in to retract and store it when not in use.

3. Lumbar Support:

   The domino 3D lumbar support is designed to stabilize your lower back. It works in conjunction with the tracking back frame, which moves to adapt to changes in your posture, providing continuous support.

4. Headrest Adjustment:

   The wide-angle headrest supports your head and neck, reducing fatigue during long periods of sitting, such as during web conferences. Adjust its height and angle to find the optimal position for your comfort.

5. 4D Armrests:

   The 4D armrests can be adjusted in four dimensions: height, depth, width, and pivot. Adjust them to support your arms and shoulders comfortably, reducing strain during typing or other desk activities.

6. Seat Depth Adjustment:

   The even pressure slide seat disperses pressure on your hips. The front and back slide adjustment helps reduce pressure behind your knees, ensuring comfort for various body types during prolonged use.

Maintenance

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

• Cleaning: Wipe down plastic and metal parts with a soft, damp cloth. For mesh fabric, use a mild soap solution and a soft brush, then blot dry. Avoid harsh chemicals or abrasive cleaners.
• Casters: Periodically clean the casters to remove dust and debris that can hinder smooth movement.
• Fasteners: Check all screws and bolts periodically and tighten them if necessary to ensure stability and safety. Do not overtighten.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading and material degradation.

Troubleshooting

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

• Chair Squeaks: Check and tighten all assembly bolts. A small amount of silicone lubricant can be applied to moving parts if the squeaking persists.
• Casters Not Rolling Smoothly: Clean any hair or debris from the caster wheels. Ensure the casters are properly inserted into the chair base.
• Chair Not Adjusting: Ensure all adjustment levers are fully engaged or disengaged as required. Check for any obstructions.
• Wobbling: Verify that all bolts are securely tightened and the chair is assembled correctly according to the instructions.
