Office Chair Base Broken

The repair or replacement of a broken office chair base should be determined based on the cause and severity of the breakage. Common causes include quality disputes, poor welding, or material issues, with repair methods including welding, temporary fixation, or direct replacement.

Analysis of Breakage Causes

The breakage of an office chair base is usually related to the material, craftsmanship, or usage scenario. Quality disputes are a common factor. For example, some models of Jingdong Heibaidiao computer chairs have experienced base steel plate breakage issues, and models originally priced at 299 yuan and now priced at 379 yuan should be purchased with caution. Welding process defects can also lead to breakage. If the welded parts are not firmly welded,脱焊 (unwelding) or cracking may occur after long-term use. In addition, insufficient load-bearing capacity of the material is another contributing factor. If the chair's designed load-bearing capacity is lower than the actual usage requirements (such as long-term use by heavier individuals), the base may break due to stress concentration.

Repair Methods

1. Welding Repair: If the broken part is made of metal and has an appropriate thickness, TIG welding is a better choice. It offers high welding precision and a small heat-affected zone, making it suitable for repairing thin metal parts. Ordinary arc welding may cause part deformation or further damage due to excessive temperature. Before welding, the broken surface should be cleaned to ensure tight contact, and after welding, the load-bearing capacity should be checked for restoration.
2. Temporary Fixation: If the breakage is not severe or an emergency fix is needed quickly, the broken part can be wrapped and fixed with iron wire. However, this method can only be used for a short period and may affect the chair's stability, so more thorough repair measures should be taken as soon as possible.
3. Component Replacement: If the chair has been in use for a long time (such as more than 5 years) or the base is severely damaged (such as multiple cracks or deformations), directly replacing the new base or the entire chair is safer and more cost-effective. After long-term use, the material may age, and there is still a risk of further breakage after repair.

Prevention Recommendations

When purchasing, prioritize chairs that have passed international safety certifications such as BIFMA, and pay attention to the material (such as thickened steel plates, high-strength plastics) and load-bearing design. During use, avoid overloading or violent shaking, and regularly check the welding parts of the base and the tightness of the screws to extend the chair's service life.
