Dangers of Office Chair Lifting Chairs

Office chair lifting chairs do pose certain dangers, with the main risk being potential explosions.

Causes of Explosions:
The metal tube beneath the chair responsible for adjusting the height is essentially a miniature pressure vessel, similar in principle to a bicycle pump. Legitimate products use nitrogen as the filling gas, which is chemically stable and can withstand high pressure. They are wrapped in thickened steel plates and undergo 120,000 lifting tests to ensure safety. However, some unscrupulous manufacturers, in an attempt to cut costs, use compressed air instead of nitrogen. Compressed air can react with the internal components of the metal tube through oxidation, accelerating component aging and generating heat, which may ultimately lead to an explosion due to pressure buildup. Additionally, thin walls of the gas spring, insufficient purity of the inert gas, and frequent lifting leading to sudden temperature increases are also common causes of explosions.

Current Risk Situation:
According to national sampling inspection results in 2023, one out of every four office chairs fails inspection, and 90% of explosion accidents are related to the use of unbranded products or chairs that have not been replaced for a long time. For example, if a chair has been in use for more than five years without replacement, the risk of internal component aging increases significantly.

Preventive Measures:

1. Strict Selection During Purchase:

   • Check the stamp on the gas spring to confirm the presence of the manufacturer's code and S09001 certification mark;
   • Prioritize products from well-known brands such as UE Furniture and Sihoo, or merchants like NetEase Yanxuan that provide inspection reports.

2. Proper Daily Use:

   • Avoid frequent lifting; it is recommended to use the chair no more than 10 times a day;
   • If the chair makes creaking sounds or the gas spring leaks oil, replace it immediately;
   • In summer, keep the chair away from heat sources such as radiators. In high-temperature environments, get up and move around every hour to prevent the gas spring from failing due to sudden temperature increases.

Conclusion:
Although the explosion risk of office chair lifting chairs exists, it can be significantly reduced through proper selection and scientific use. Consumers should be wary of low-priced unbranded products, regularly inspect the condition of their chairs, and follow safe usage principles to ensure their own safety.
