Hazards of Office Chairs

The hazards of office chairs mainly include two categories: safety risks and health threats, as detailed below:

Safety Risks

1. Explosion Risk
   The pneumatic rod in an office swivel chair is the core component for height adjustment, but poor-quality pneumatic rods pose serious safety risks. Their thin tube walls, impure inert gases (or even the use of compressed air as a substitute), or excessive temperatures caused by frequent chair adjustments can all trigger explosions. Additionally, if a blast-proof steel plate with a thickness of at least 2 millimeters is not installed between the pneumatic rod and the seat cushion, metal fragments from the explosion may directly strike the body, causing fatal injuries.

2. Component Breakage
   If the material strength of the swivel chair's five-star base, chassis, or casters is insufficient (e.g., thin tube walls), they may suddenly break during daily use, causing the user to fall. Multiple recall incidents in the market indicate that issues such as backrest breakage and bolt failure are also common, potentially leading to falls, fractures, and other serious consequences.

3. Stability Issues
   Some office chairs have design flaws that make them prone to tipping over when leaning forward, backward, or sitting sideways, especially on smooth floors or when moving quickly, which may result in bruises or fractures.

Health Threats

1. Hazards of Prolonged Sitting
   Prolonged sitting with improper posture significantly increases lumbar spine pressure (from about 100 kilograms when standing to 180 kilograms), leading to issues such as lumbar disc herniation and cervical spine overload. Data shows that over 65% of office workers suffer from lumbar spine diseases, and prolonged sitting is also closely related to chronic conditions such as obesity and cardiovascular disease.

2. Hazards of Formaldehyde
   Some office chairs use poor-quality adhesives or artificial boards, resulting in excessive formaldehyde emissions. As a Class I carcinogen, long-term exposure to formaldehyde may cause dizziness and fatigue, while high concentrations can damage the nervous system, immune system, and liver, even increasing the risk of cancers such as nasopharyngeal carcinoma and leukemia.

Recommendations: When purchasing an office chair, pay attention to pneumatic rod certifications (such as SGS, TUV), the material of the five-star base (preferably steel or thickened aluminum alloy), and formaldehyde test reports; avoid frequent height adjustments during use, maintain proper sitting posture, and regularly check the firmness of components to reduce risks.
