The air pressure swivel chair adopts the air spring, which is commonly known as the air pressure bar. The air pressure bar is filled with inert gas, and the adjustment button realizes the lifting of the seat through the change of pressure difference.

In 2017, a netizen in Anhui posted that a colleague's office chair also exploded. The base of the chair and the surface of the chair have been separated and broken into two parts. The computer mainframe next to it has also been affected and destroyed.

In 2009, a 14-year-old boy in Jiaozhou, Shandong Province was seriously injured by the explosion of a swivel chair at home, and finally died after ineffective rescue.

According to insiders, at present, the quality of pneumatic rods on the market is uneven, and the cost of a pneumatic rod ranges from a few yuan to dozens of yuan.

If the tube wall of the air pressure rod is too thin, the inert gas is impure, or even the compressed air is used as inert gas, it may cause the swivel chair to explode. In addition, the seat rises and falls repeatedly and frequently during use, resulting in excessive temperature and explosion.

The explosion-proof steel plate is not installed, and the work and materials are cut corners

In order to prevent the explosion of office swivel chair to the greatest extent, the effective protection method is to add a certain thickness of explosion-proof steel plate between the air pressure rod and the swivel chair cushion.

It is reported that the thickness of the explosion-proof steel plate shall not be less than 2mm. The purpose is to prevent the explosion of the air pressure rod during use and the breakdown seat from causing injury to the human body.
