Step 1: Prepare the Base

Insert the five casters into the holes at the end of each leg of the chair base. Push firmly until they click into place. Then, place the gas lift cylinder into the center hole of the assembled chair base, ensuring it sits securely.

Step 2: Assemble the Seat

Align the seat mechanism with the pre-drilled holes on the underside of the seat cushion. Secure it with the provided screws, ensuring the front of the mechanism faces the front of the seat. Attach the armrests to the seat assembly using the designated screws.

Step 3: Attach the Backrest and Headrest

Connect the backrest to the seat assembly using the designated screws, ensuring a firm connection. Slide the headrest into the slots at the top of the backrest.

Step 4: Final Connection

Carefully place the assembled seat, backrest, and armrests onto the gas lift cylinder. The tapered hole in the seat mechanism should fit snugly over the top of the gas lift. Once assembled, sit on the chair to firmly seat the components.

5. Operating Instructions and Adjustments

The SIHOO B100 chair offers several adjustment features to customize your seating experience:

5.1. Seat Height Adjustment

To adjust the seat height, locate the lever on the right side under the seat. Pull the lever up while sitting to lower the seat, or pull it up while standing to raise the seat. Release the lever at your desired height.

5.2. Recline Function and Tension

The chair features a recline function with multiple locking angles (110°, 123°, 135°). To recline, pull the recline lever (usually on the left side) and lean back. Release the lever to lock the backrest in position. The recline tension can be adjusted by turning the round knob located under the seat, allowing you to control the resistance when reclining.
