Gu Jia Office Chair Installation

The installation process of the Gu Jia office chair is relatively simple and can generally follow the bottom-up installation logic of conventional office chairs. The specific steps are as follows:

1. Install the casters and gas lift
   Align the casters (universal wheels) with the mounting holes on the chair legs and press firmly to embed them securely, ensuring that each caster is properly installed. Then, insert the gas lift vertically into the center hole of the chair legs. Note that the metal end of the gas lift should face down and the plastic end should face up. After insertion, gently shake it to confirm there is no looseness. The gas lift is the core component for adjusting the chair's height, so it must be installed vertically to avoid tilting, which could lead to subsequent usage failures.

2. Secure the base and seat
   Place the base (the component that connects the gas lift to the seat) on the bottom of the seat. After aligning the screw holes, use the provided screws and tools (such as a Phillips screwdriver) to fix it. When installing, tighten the screws evenly to avoid gaps or misalignment between the base and the seat, which could affect the chair's stability. Some Gu Jia office chairs may have integrated adjustment handles (such as for height adjustment and recline functions) on the base. Ensure that the handles face outward for easy operation.

3. Connect the backrest and seat
   Align the metal bracket or clip of the backrest with the mounting position on the back of the seat and fix it with screws or directly snap it in (depending on the model design). If it is fixed with screws, use tools to tighten them; if it is a clip-on type, listen for a 'click' sound to confirm it is locked. In this step, pay attention to aligning the angle between the backrest and the seat to avoid misalignment after installation.

4. Assemble the base and gas lift
   Lift the base part with the installed backrest and seat and align it with the top of the gas lift. Press down vertically to make the base fully fit with the gas lift. Some models may require a slight rotation of the base to lock the structure, so refer to the instruction manual for confirmation. After installation, gently shake the chair to check if the connection between the gas lift and the base is secure.

5. Install the armrests and headrest (if applicable)
   If the chair is equipped with armrests, align them with the mounting holes on both sides of the seat and fix them with screws. The headrest should be installed on the top of the backrest using clips or screws. When installing, adjust the height or angle of the armrests (if adjustable) to ensure they are level with the seat; for the headrest, confirm that it is installed in the correct direction to avoid inversion.

Precautions: Before installation, check that all accessories are complete (such as screws and tools) and read the instruction manual to confirm any special designs. Avoid applying excessive force during installation to prevent damage to the components. After completion, test all functions of the chair (such as height adjustment, recline, and rotation) to ensure they are working properly. If you encounter issues such as clips that cannot be locked or misaligned screw holes, it is recommended to contact after-sales service for assistance.
