Office Chair Leg Removal

There are mainly two methods for removing the legs of an office chair:

Method 1: Shaking and Lifting Method

This method is suitable for some office chair five-star bases that are fixed by snaps or friction. During operation, step on the five-star base frame below with one foot to stabilize it, preventing the chair from sliding or tipping over during the process. Then, grab both sides of the seat cushion with your hands, and shake it left and right while lifting it upwards at the same time. Keep doing this action, shake for a while longer, and use the looseness generated by the shaking and the upward lifting force to gradually separate the connection between the five-star base and the seat cushion. If there is no response after following the above steps, it may be that the grasping position is not appropriate. At this time, grab the other two sides of the seat cushion and repeat the above action of shaking left and right and lifting upwards until the five-star base is removed. This method mainly relies on the external force generated by human effort to overcome the fixing force between the five-star base and the seat cushion. The operation is relatively simple, but it requires a certain amount of patience and strength, and is suitable for some office chairs with relatively simple structures and not very tight connections.

Method 2: Removing the Snap Ring or Tapping Method

First, gently lay the chair on the ground upside down, which makes it easier to view the structure at the bottom of the central column. Then, check whether there is a flat washer snap ring at the bottom of the central column. If there is a flat washer snap ring, use an appropriate tool, such as a screwdriver, to remove the flat washer snap ring. After the flat washer snap ring is removed, the five-star base that was originally fixed by the snap ring will lose its restraint, and at this time, you can pull out the old five-star base and then replace it with a new one. If there is no flat washer snap ring, it means that the connection between the five-star base and the steel column is a conical structure, and they are pressed together by weight. In this case, you can gently tap the connection part between the five-star base and the steel column with a hammer. The vibration and impact force generated by the tapping will gradually loosen the five-star base until it comes off. After that, install the new five-star base and ensure it is firmly installed. This method requires certain tools and operating skills. Pay attention to the force when tapping to avoid damaging other parts of the chair.
