NetEase Office Chair Breakage

There are indeed cases of breakage in NetEase office chairs. Here are specific cases and analyses:

I. Specific Breakage Cases

1. Breakage of a Thousand-Yuan Ergonomic Chair Leading to Injury
   A user reported that the NetEase Yanxuan ergonomic chair, purchased for 1499 yuan, suddenly broke during use, causing the user to fall off the chair. Such cases indicate that even higher-priced products may have structural safety hazards.

2. Base Breakage After Long-Term Use
   A consumer purchased a multifunctional ergonomic chair from the NetEase Yanxuan platform on January 19, 2021. In early 2023, cracks appeared at the connection between the seat and the base, followed by severe base breakage, rendering the backrest unable to lock. By 2024, the chair was completely unusable, exhibiting issues such as a front-low, back-high tilt, sliding, base tearing, and failure of the height adjustment function. This case suggests that some products may have insufficient durability, with structural strength declining after long-term use.

3. Connection Breakage After One and a Half Years of Use
   In April 2022, a user purchased a NetEase Yanxuan ergonomic chair from a JD.com self-operated store. After one and a half years of use (October 9, 2023), the connection between the base and the backrest suddenly broke during normal reclining, causing the user to fall. This case indicates that breakage may occur due to design or material defects even before the product reaches its stated lifespan.

II. Breakage Cause Analysis

1. Material or Process Defects
   Breakage may stem from insufficient material strength in key components such as the base and connectors, or flaws in the manufacturing process (e.g., loose welding, injection molding defects), leading to fatigue breakage under long-term stress.

2. Design Structure Issues
   If the chair's load-bearing design does not fully consider dynamic usage scenarios (e.g., reclining, rotating), or if the connection structure has stress concentration points, component damage may be accelerated.

3. Usage Environment and Maintenance
   Long-term overloading, frequent movement, or failure to regularly check screw tightness may exacerbate component wear. However, according to case descriptions, some breakages occurred under normal usage conditions, indicating potential product flaws.

III. Recommendations and Reminders
Consumers should carefully review product evaluations before purchase, focusing on long-term usage feedback. During use, avoid overloading or rough handling, and regularly check for loose connectors. If cracks, unusual noises, or other abnormalities occur, immediately stop using the chair and contact after-sales service.
