How to Inspect Office Chairs

If the user's requirement is to disassemble and inspect an office chair, follow these steps:

1. Removing the Chair Wheels Hold the chair foot with one hand and grasp the chair wheel with the other hand, pulling it out perpendicular to the slot. If the connection is tight, gently shake it left and right before pulling to avoid deforming the chair foot or slot due to excessive force. Chair wheels are usually made of plastic and may become difficult to remove after long-term use due to wear. In this case, a small amount of lubricating oil can be dripped into the connection to assist in separation.

2. Separating the Gas Lift from the Base

   • Snap Ring Fixed Structure: Use snap ring pliers to clamp the snap ring at the connection between the gas lift and the base, and then take it out to separate the components. The snap ring is made of metal, so wear gloves during operation to prevent scratches.
   • Nut Fixed Structure: Use an appropriate wrench (such as an adjustable wrench) to unscrew the nut at the top of the gas lift, and then pull the gas lift straight up. If the nut is rusty, spray rust remover and let it sit for 5 minutes before operating.
   • Hydraulic Lift (for executive chairs): Turn the chair upside down and tap evenly around the base steel ring with a rubber mallet to loosen the internal clips and then separate them. If it still cannot be disassembled, step on the bottom of the hydraulic lift with your foot while pulling the chair body upward with your hand to assist in separation.

3. Disassembling the Seat and Backrest Use a screwdriver to unscrew the fixing screws that connect the seat, backrest, and gas lift. If the screws are rusty, drip lubricating oil (such as WD-40) and let it sit for 10 minutes before operating. Some office chairs have a hidden screw design, and you need to lift the chair surface fabric or plastic cover to find the screw holes. After disassembly, record the positions of the screws to avoid misinstallation during reassembly.

4. Deep Disassembly of the Base (for executive chairs)

   • After turning the chair upside down, use a torx wrench or screwdriver to rotate the screws connecting the base and the chair body counterclockwise, and at the same time, tap the edge of the base lightly with a rubber mallet to assist in loosening.
   • Check if the base is fixed to the seat cushion or casters. If so, unscrew the corresponding screws and remove them. Some bases have a spring structure inside. When disassembling, press the spring with your fingers to prevent it from popping out and causing injury.

Precautions:

• Before disassembly, it is recommended to observe the overall structure. For chairs with a modular design, disassemble them component by component to avoid forcibly damaging the connection points.
• Small parts (such as screws and snap rings) should be stored in containers by category to avoid loss or confusion.
• For special structures (such as adjustable armrests and cable management slots), refer to the instruction manual or contact the manufacturer to prevent damage caused by misoperation.
• During reassembly, follow the reverse order and check that all components are firmly connected to avoid leaving safety hazards.
