Adjustable Office Chair Installation

The installation steps for adjustable office chairs vary depending on the model. Here are the installation methods for some common models:

Heibaidiao P1 (P101BXA)

1. Install the chair wheels and five-star base: Invert the five-star base and insert the five chair wheels into the slots one by one. Ensure the wheels are securely installed, then flip the base so the wheels touch the ground.
2. Install the gas lift: Insert the thicker end of the gas lift vertically into the assembly hole at the center of the five-star base. Ensure it is inserted deeply enough and does not wobble.
3. Install the armrests: Pass the screws through the washers and manually screw them into the screw holes where the armrests connect to the seat cushion to about one-third depth. Then, use a wrench to tighten them one by one, avoiding tilted or loose screws.
4. Connect the seat cushion and backrest: Align the seat cushion with the top of the gas lift and insert it. Then, install the backrest steel plate and use the provided screws to secure the connection between the plate and the seat cushion.
5. Install the neck pillow and shell: Secure the neck pillow connector to the backrest, then install the neck pillow and adjust its angle. Finally, secure the backrest shell, ensuring all components are tight.

Heibaidiao E2pro (E218BLA)

1. Install the chair wheels and gas lift: Flip the five-star base, insert the five chair wheels, and then insert the gas lift, ensuring it is aligned with the center of the base.
2. Install the armrests: Align the armrests with the assembly holes under the seat cushion, insert the screws from the bottom, and initially secure them. Then, use a tool to tighten the screws, ensuring the armrests are level and stable.
3. Install the base plate: Place the base plate at the bottom of the seat cushion and use screws to secure the connection between the base plate and the seat cushion. Ensure the screws are fully inserted.
4. Secure the backrest: Align the installation holes of the backrest and the base plate, insert the screws, and tighten them to ensure a tight connection between the backrest and the base plate without gaps.
5. Assemble the whole chair: Align the entire chair with the top of the gas lift and insert it into the hole in the base plate. Install the headrest and adjust its height. Finally, check that all screws are tightened.

Universal Multi-functional Computer Chair

1. Install the casters and five-star base: Insert the movable casters into the slots of the five-star base, ensuring they can rotate 360 degrees horizontally without jamming.
2. Install the lift rod: Flip the five-star base upright and insert the lift rod vertically into the hole in the middle of the base, ensuring the insertion depth meets the requirements.
3. Install the tray and backrest: Attach the computer chair tray to the top of the lift rod, then install the backrest bracket and backrest mesh. Use screws to secure the connection between the bracket and the tray.
4. Install the armrests: Align the armrests on both sides with the installation holes on the sides of the seat cushion, ensuring the correct orientation. Insert the screws and tighten them to avoid tilted armrests.
5. Final inspection: After installation, check that all screws are tightened, and the lift and rotation functions are normal to ensure the chair is safe to use.
