Office Chair Report
The report on office chairs mainly focuses on three aspects: standard research, quality spot checks, and international strength testing.
I. Special Research Report on 'QBT 2280-2016 Office Furniture - Office Chairs' This report systematically outlines the core framework of China's office chair industry standards, covering key indicators such as definition boundaries, ergonomic parameters, safety performance, durability, and limits on harmful substances. The report emphasizes that the 2016 version of the standard directly determines the comfort and health support capabilities of chairs by specifying quantitative requirements for ergonomic parameters (such as seat depth, backrest angle, and armrest height). At the same time, strict regulations on safety performance (such as structural stability and load-bearing capacity) and durability (such as chair leg fatigue testing and fabric abrasion resistance) serve as the 'lifelines' for industry quality control. Additionally, the report proactively explores future directions for standard revisions, including adaptive adjustments to trends such as the application of new materials and intelligent functions.
II. Weekly Quality Report: Poor Quality of Office Chairs Spot check results from the State Administration for Market Regulation reveal significant quality hazards in office chairs. Out of 90 batches of products inspected in 2019, 21 batches failed, with issues concentrated on flame retardancy (flammable materials increasing fire risks), caster wear (causing movement stuttering or damage), safety (structural looseness leading to tipping), and formaldehyde emissions (exceeding limits and endangering human health). Among these, pneumatic swivel chairs pose an 'explosion' risk due to inconsistent quality of gas springs, making them a major area of quality concern. The report points out that some companies reduce costs by using inferior gas springs or omitting safety valve designs, leading to violent explosions when gas pressure becomes uncontrollable, seriously threatening user safety.
III. EN 1335-2 European Strength Quality Inspection Report for Office Chairs The European standard EN 1335-2 establishes an international framework for evaluating office chair strength through systematic mechanical performance testing. This standard simulates real-world usage scenarios (such as repeated sitting pressure, armrest load-bearing, and caster rolling) to conduct independent strength tests on core components including seats, backrests, armrests, bases, gas lifts, and casters, accurately identifying potential weak points. For example, gas lifts must pass high-pressure cycling tests to verify lifting stability, while casters must endure tens of thousands of rolling wear tests to ensure durability. Standardized testing environments (such as temperature and humidity control) and conditions (such as load size and frequency) ensure result comparability across different laboratories and product batches, providing reliable quality references for global consumers.
