Office Chair Spindle Collapse

The repair of an office chair spindle collapse depends on the specific damaged component. Common causes include gas spring sagging or base cracking, which can be resolved by adjusting or replacing parts. During the warranty period, it is recommended to contact the merchant first.

Repair Method for Gas Spring Sagging

If the spindle collapse is caused by gas spring failure (manifested as abnormal lifting function), try manually adjusting the bottom structure of the gas spring. Use an Allen wrench to rotate the adjustment ring at the bottom of the gas spring counterclockwise by 2-3 turns. This operation may restore the gas spring's sealing and thus restore the lifting function. Note: Before adjusting, ensure that the gas spring has no air leaks or physical deformation. If it still fails to rise after adjustment, it indicates that the internal seals of the gas spring are aged or damaged, and a new gas spring needs to be replaced.

Repair Method for Base Cracking

If the collapse is caused by base cracking (manifested as chair tilting or structural looseness), the entire base needs to be replaced. You can search for matching parts on e-commerce platforms using keywords such as "computer chair base + model", with prices typically ranging from 30-80 yuan. When replacing, note the following:

1. Take photos of the screw positions before removing the old base to avoid incorrect installation;
2. The new base must be compatible with the original chair model (such as the hole spacing of the five-star foot and the size of the gas spring interface);
3. After installation, test the chair's stability to ensure there is no wobbling or abnormal noise.

Handling Suggestions During the Warranty Period

If the office chair was purchased within 3 months and the collapse is not caused by human factors (such as heavy impact or unauthorized disassembly), it is recommended to contact the merchant first. According to the Consumer Rights Protection Law and the warranty terms of most merchants, core components (such as gas springs and bases) are eligible for free repair or replacement during the warranty period. When contacting, provide purchase proof (such as order screenshots or invoices) and photos of the damaged parts to expedite the after-sales process.

Tip: After long-term use, the nitrogen in the gas spring may leak, causing lifting failure, and the plastic parts of the base may also crack due to aging. Avoid overloading during daily use (it is recommended that the load capacity be ≤120kg) and regularly check the tightness of the screws to extend the lifespan of the office chair. If the problem recurs after self-repair, it is recommended to contact a professional repair technician or replace the chair with a new one.
