Office Chair Disassembly Method
The disassembly method of office chairs varies depending on the model and design. Here are the specific steps for two common types:

Disassembly Steps for the Beๆฐช Office Chair BC03Q Premium Edition
Headrest Disassembly
Pull the headrest to its highest position, press down firmly on the thin metal strip in the middle while holding it, and pull out the headrest once you feel the locking mechanism loosen. If the buckle is tight, you can insert a hard card (such as a bank card) into the gap to assist in prying it open, avoiding direct pulling that may cause the metal strip to deform.Armrest Disassembly
Invert the chair onto a stable, elevated platform (such as a workbench), and use the hex wrench that comes with the chair to loosen the fixing screws beneath the armrests. Be sure to keep the screws to prevent loss during subsequent reassembly. If the screws are rusty, you can spray a small amount of lubricant to aid in disassembly.Separation of the Backrest and Base
Use the hex wrench again to remove the screws at the connection between the backrest and the base, usually requiring the removal of 2-4 screws. After disassembly, gently shake the backrest to confirm complete separation, avoiding forceful pulling that may break the plastic buckles.Separation of the Five-Star Base and Gas Spring
Use a rubber mallet (or an ordinary hammer wrapped in cloth) to tap the edges of the five legs of the five-star base to loosen the connection. Then, tap the center of the base plate to prompt the separation of the gas spring from the base. Control the force during tapping to avoid damaging the internal structure of the gas spring.Wheel Disassembly
Simply grasp the wheels and pull them outward. If the wheels are stuck due to long-term use, you can insert a screwdriver into the gap between the wheels and the five-star base to gently pry them open, or spray a small amount of lubricant and wait for 5 minutes before attempting to pull them out again.
Disassembly Steps for the Gas Rod of a General-Purpose Office Chair
Adjust the Chair Height
Face the chair directly, step on the five-star base to keep it stable, pull up the height adjustment lever and hold it, and raise the chair to its highest position. This step releases the internal pressure of the gas rod, reducing the difficulty of disassembly.Separation of the Gas Rod and Seat
Hold the edges of the seat with both hands, and shake it up and down with force according to the chair's service life, then slowly pull it out. If the gas rod and seat are too tightly connected, you can try gently tapping the bottom edge of the seat with a rubber mallet, or apply a hot towel to the connection to soften the plastic before trying again.
Precautions:
- Take photos of the connection positions of each component before disassembly for easy reference during subsequent reassembly.
- Keep all small parts such as screws and buckles, and store them separately to avoid loss.
- If the gas spring shows signs of air leakage, abnormal noise, or inability to adjust height, it is recommended to replace it with a new gas rod directly rather than forcing disassembly to prevent injury from high-pressure gas ejection.
