Office Chair Evaluation Center

Yingshanhong Intelligence (Beijing) Testing Technology Co., Ltd. is a professional office chair evaluation center that provides comprehensive office chair quality testing services. The following is an introduction from the dimensions of testing content, scope, cycle, and projects:

Testing Content Focuses on Core Performance Indicators
The institution's testing of office chairs revolves around safety, stability, and durability. Structural testing mainly evaluates whether the connections between various components of the chair body are firm, such as the welding process of the five-star base and the pneumatic rod, and whether the fixing methods of the chair back and the seat surface meet mechanical requirements. Load-bearing testing is divided into static and dynamic categories. Static load-bearing testing assesses the chair's ability to withstand the maximum weight in a stationary state (e.g., whether it deforms under a 200kg load), while dynamic load-bearing testing simulates the impact tolerance when users frequently sit up and move. Stability testing covers front-tilt and side-tilt scenarios, determining the chair's anti-tipping ability in non-horizontal states through tilt angle testing, such as whether the chair feet lift off the ground when tilted forward by 15°. Durability testing uses fatigue testing machines to simulate long-term use, evaluating the impact of actions such as wheel rolling and repeated backrest leaning on material lifespan.

Testing Scope Covers Major Regions Across the Country
The service network extends to economically active regions such as North China, East China, and South China, accepting samples sent from cities like Beijing, Shanghai, Guangzhou, and Shenzhen. Enterprises or individuals can send office chairs to the laboratory via logistics, and the testing institution provides full tracking services to ensure the safe transportation of samples.

Testing Cycle is Flexible and Can be Expedited
The conventional testing process issues reports within 5-7 working days after the samples arrive at the warehouse. If enterprises need to obtain results quickly (e.g., before launching new products), they can apply for expedited services, with testing completed in as fast as 3 working days. The report includes data records, problem analysis, and improvement suggestions, such as pointing out that the insufficient sealing of the pneumatic rod in a certain model of chair may lead to air leakage, or that the excessive hardness of the wheel material may scratch the floor.

Testing Projects are Comprehensive and Detailed
In addition to the above core projects, it also includes structural strength testing (e.g., the deformation rate of the chair back when subjected to a 100kg pressure), material safety testing (testing whether the content of harmful substances such as formaldehyde and heavy metals meets national standards), and functional component reliability testing (e.g., the durability times of lifting mechanisms and rotation functions). The testing standards refer to national standards such as Office Chairs (GB/T 38733-2020) to ensure the authority of the results.
