Hidden Dangers in Office Chairs

The hidden dangers in office chairs mainly include safety hazards, explosion risks, component failure risks, and health threats.

Safety hazards: There have been multiple recalls of office chairs in the market, with core issues centered around backrest breakage and bolt failure. These component failures can directly cause users to fall and get injured, with a cumulative total of 19 related injury reports so far. Such hazards are often related to insufficient material strength or structural design flaws and may occur suddenly during use, resulting in accidental injuries.

Explosion risks: The explosion risks of pneumatic swivel chairs mainly stem from poor-quality pneumatic rods and the lack of explosion-proof measures. If the wall of the pneumatic rod is too thin, the inert gas is impure, or compressed air is used as a substitute, frequent lifting and lowering leading to a temperature increase may trigger an explosion. In addition, some products do not have explosion-proof steel plates with a thickness of ≥2 millimeters installed between the pneumatic rod and the seat cushion, resulting in failed safety tests and further increasing the explosion risk.

Component failure risks: If there are quality issues with components such as the five-star base, chassis, and casters of a swivel chair, breakage or detachment may occur. For example, to reduce costs, materials with thin walls or poor strength may be used to manufacture the five-star base, which may suddenly break during daily use, causing the user to fall and get injured. Problems such as chassis breakage and caster detachment are also common and are mostly related to material or process defects.

Health threats: Prolonged sitting is a common health hazard faced by office workers. When standing, the lumbar spine bears a pressure of about 100 kilograms, but when sitting incorrectly, this pressure can soar to 180 kilograms. Long-term overload can easily lead to cervical and lumbar spine problems. Data shows that more than 65% of office workers are troubled by lumbar spine issues. In addition, some unqualified office chairs have problems with excessive formaldehyde, which may release carcinogens and pose a long-term threat to the health of users.
