Is the Office Chair Safe?

The safety of an office chair depends on the quality of its core components, especially the gas spring. Qualified products are generally safe under normal use, but low-quality gas springs pose an explosion risk, so careful selection and proper use are essential.

The Gas Spring is Key to Safety; Low-Quality Products Pose Significant Risks

As the core component for adjusting the height of an office chair, the safety of the gas spring directly determines the overall risk. Qualified gas springs feature thickened tube walls, are filled with high-purity nitrogen, and are equipped with explosion-proof steel plates, making the probability of an explosion extremely low under normal use. However, to reduce costs, low-quality gas springs often use thin-walled metal tubes, compressed air (which contains oxygen and is flammable), and lack explosion-proof designs. Under frequent height adjustments or exposure to high temperatures and sunlight, the tube walls may rupture due to a sudden increase in pressure, causing metal fragments to fly out. For example, in 2013, Ms. Liu in Xiamen was impaled in the lower body by an exploding gas spring. In 2024, the State Administration for Market Regulation found during inspections that 23.3% of non-compliant chairs had issues such as overly thin tube walls and impure gases in their gas springs, making the explosion risk of these products significantly higher than that of qualified products.

Strictly Verify Standards and Certifications When Purchasing

To avoid risks, pay close attention to the following standards when selecting an office chair:

• Execution Standard: Look for QB/T 2280-2016 (the industry standard for office chairs), which explicitly requires gas springs to pass durability and explosion-proof tests.
• Certification Marks: Check if the gas spring has 5G5 certification (an internationally recognized safety certification for gas springs). Some brands may also display third-party testing marks such as "SGS" or "TÜV."
• Brand and Testing: Prioritize brands that have passed over 100,000 height adjustment tests (such as Xiamumu and Lianyou). These products typically use thickened tube walls (≥2.5mm) and pure nitrogen filling, offering more reliable explosion-proof performance.

Avoid Improper Use in Daily Operations

Even with qualified products, improper use can accelerate component wear and increase risks:

• Avoid Frequent Height Adjustments: It is recommended to adjust the height no more than 50 times per day. Excessive use can cause the internal seals of the gas spring to age, increasing the risk of air leaks or explosions.
• Prevent High-Temperature Exposure: Keeping the chair in direct sunlight or high-temperature environments (such as near radiators) for extended periods can cause the gas inside the spring to expand, exceeding the tube wall's pressure tolerance.
• Regularly Inspect Components: If you notice any issues such as difficulty in adjusting the height, unusual noises, or cracks on the surface of the gas spring, stop using the chair immediately and contact after-sales service for replacement.

Additionally, long-term user experience is also related to the load-bearing structure (such as the material of the five-star base), the elasticity of the mesh fabric, the sturdiness of moving parts, and after-sales support. When purchasing, consider these factors comprehensively to enhance safety and comfort.
