Office Chair Base Broken

Admin October 19, 2026

If the base of your office chair is broken, you can choose to repair or replace it based on the extent of the damage. Here are the specific methods:

If the base is loose or makes abnormal noises, first lay the chair flat on a level surface. Use a screwdriver to remove the screws securing the base beneath the seat. Carefully check whether the connections between the base, the gas lift, and the seat cushion are loose. If you find that the screw holes are worn, you can replace them with longer screws or fill the holes with wood glue and wood shavings to reinforce them, thereby enhancing the stability of the connections. If the base is deformed, use a wrench to gently straighten it back into place. During the repair process, ensure that the alignment holes of the base and the gas lift are aligned, and then tighten the screws in a diagonal sequence to prevent further issues caused by uneven force.

If the base is cracked or damaged, different treatments are required depending on the material of the base. If the base is made of plastic, you can apply AB glue to the cracks and then attach metal sheets or carbon fiber cloth to strengthen its strength. If it is a wooden base, you can replace it with a metal square tube of the same size. After measuring the dimensions of the original base, purchase a base of the same model and replace it according to the installation steps.

If the connection between the base and the gas lift is damaged, carefully check whether the gas lift is deformed. If the gas lift is deformed, it may be necessary to replace both the base and the gas lift together to ensure the normal use of the office chair.

In addition, you can also opt for professional repair services.
