Office Chair Assembly Guide

Refer to the following general assembly steps for assembling an office chair:

I. Unpacking and Inspection Upon receiving the office chair package, first unpack all the parts and check them against the inventory list to confirm that there are no missing or damaged items. The basic components of an office chair typically include the seat, backrest, chair legs, and small accessories such as screws and clips. Some models may also come with additional components like armrests, cup holders, or storage bags. During inspection, pay attention to whether there are any scratches or damages on the surface of the parts. If any issues are found, contact after-sales service promptly.

II. Assembling the Chair Legs and Seat

1. Chair Leg Installation: Start with the chair legs. Choose the operation method according to their connection type:
   • For screw-fixed types, align the chair legs with the pre-drilled holes on the bottom of the seat. Use the provided tools (such as an Allen wrench) to gradually tighten the screws to ensure a secure connection.
   • For clip-on or direct-insertion types, align the holes and press firmly until you hear a 'click' sound, indicating that the clip is in place. For insertion types, additionally check if the anti-loosening screws are tightened.
2. Stability Test: After installation, gently shake the chair legs to confirm that there is no looseness or abnormal noise, preventing the risk of tipping over during subsequent use.

III. Installing the Backrest

1. Hole Alignment: Align the screw holes on the backrest with those on the back of the seat one by one. Adjust the angle of the backrest to a comfortable position (for adjustable models, set the initial angle in advance).
2. Screw Fixation: Insert the screws from inside or outside the seat and use tools to tighten them in stages, avoiding excessive force on one side that could cause misalignment of the holes. After completion, check again for smooth connection between the backrest and the seat, ensuring there are no gaps or wobbling.

IV. Assembling Detail Components

1. Armrest Installation: If the chair is equipped with armrests, align them with the pre-drilled holes on both sides of the seat, fix them with screws, and adjust the height if there is an adjustment function.
2. Additional Accessories: Determine the installation positions of accessories such as cup holders and storage bags according to the instructions. They are usually fixed to the sides or bottom of the seat with clips or screws. Pay attention to balancing the weight distribution on both sides.

V. Function Testing and Reinforcement

1. Test Sitting Inspection: After all assembly is complete, sit on the chair to test its stability. Focus on checking whether the chair legs are stable, whether the backrest adjustment is flexible, and whether the armrests are firm.
2. Looseness Reinforcement: If any looseness is found, immediately use tools to retighten the corresponding screws or clips to prevent parts from falling off or being damaged due to long-term use.

Precautions: Keep the assembly environment clean to avoid losing small parts. For complex structures (such as the installation of a pneumatic rod), it is recommended to refer to the instruction manual or video tutorial for the specific model to ensure safe operation.
