What security details should I pay attention to when using the Office swivel chairs?

Some inferior Office swivel chairs are prone to explode when used for a long time. What are the reasons for these problems? There are basically two situations that cause an explosion.

Excessive force or frequent adjustment of the handle may also cause the quality of the swivel chair to be worn, which may easily cause instability on the air lever. Uniform stress and uneven wear over a long period of time can create a potential explosion hazard.

Some people will follow the process of removing the chair to deflate, which is very dangerous! It's best to have a professional check and maintain your chair regularly to check your Office swivel chair regularly.
