Office Chair Black Material
The issues of 'black material' in office chairs mainly include the use of shoddy scrap materials and unqualified materials with safety hazards.
Use of shoddy scrap materials: Some unscrupulous merchants, in order to reduce costs, use shoddy scrap materials to make office chairs. These scrap materials are of unknown origin and extremely poor quality, possibly containing a large amount of impurities, harmful substances, and may even be recycled waste materials. For example, a man who spent 96 yuan on an office chair experienced discomfort after using it for a while. Upon disassembly, he found that the interior of the chair was filled with shoddy scrap materials that crumbled at the touch. These inferior materials not only affect the service life of the office chair but may also release harmful gases such as formaldehyde and benzene. Long-term exposure can cause serious harm to human health, triggering respiratory diseases and allergic reactions.
Unqualified materials with safety hazards: CCTV has exposed issues with unqualified office chairs, with the use of inferior gas springs being a prominent problem. Inferior gas springs may have poor sealing and impure gas, which can lead to explosions under long-term use or external impact, causing serious injuries to users. In addition, the five-star bases of some office chairs also pose safety risks. Some merchants, in order to save costs, do not install explosion-proof steel plates and use thin-walled, low-strength materials. When subjected to heavy loads or collisions, the five-star bases are prone to breakage, causing users to fall and get injured.
To avoid purchasing office chairs with 'black material' issues, consumers should choose reputable channels and well-known brands when shopping, and check the product's quality inspection reports and relevant certification marks. At the same time, pay attention to observing the appearance and materials of the office chair, and inspect the quality and workmanship of key components such as the gas spring and five-star base. During use, regularly inspect all components of the office chair and replace or repair them promptly if any abnormalities are found to ensure safety.
