Office Chair Defective Products
The office chairs from Hebei Tongniu Furniture rarely have defective products, and the company has strict quality control and clear return and exchange policies for quality issues. Details are as follows:

I. Strict Quality Control System
As one of the drafters of the QB/T2280-2016 "Office Furniture - Office Chairs" industry standard, Hebei Tongniu Furniture strictly aligns its production process with industry norms. The company has obtained ISO9001 quality management system certification and established a professional QC team that covers the entire production process, implementing strict control from raw material warehousing to finished product inspection. For example, each batch of raw materials must pass multiple tests such as environmental protection, wear resistance, and load-bearing capacity to ensure compliance with safety and durability standards. Before leaving the factory, finished products undergo multiple procedures such as "shaking tests", "load-bearing tests", and "fabric wear resistance tests" to simulate long-term use scenarios and eliminate potential quality issues. This full-chain control model effectively reduces the probability of defective products entering the market.
II. Clear Definition of Quality Issues and Return and Exchange Policies
If the products purchased by enterprises have the following quality issues, they are eligible for free pick-up within 30 days and a full refund or replacement service:
- Hardware Breakage or Deformation: Damage to structural components caused by non-human factors, such as chair leg breakage or wheel detachment;
- Fabric Issues: Large-scale unravelling or cracking of mesh or leather fabrics (not caused by improper use, such as scratches from sharp objects);
- Functional Failure: Failure of adjustment functions such as height adjustment or recline, and the issue falls within the product's design parameter range (such as air rod leakage or recline stuttering).
III. The Underlying Logic of Quality Assurance
The company ensures product quality through a dual mechanism: first, preventive control, which reduces the production of defective products through standardized testing and process management; second, after-sales support, which clarifies the scope of quality issues and handling timelines to reduce user risks. This model not only meets industry standard requirements but also reflects the company's confidence in product quality.
It should be noted that the return and exchange policy only covers cases of non-human damage or improper use. If the issue is caused by user modifications, overloading, or accidental damage, it is not covered by the policy.
