Office Chair Breakage

Office chair breakage usually occurs at the connection between the backrest and the base, as well as in the adjustment mechanisms. Pneumatic lift chairs may also face the risk of explosion and breakage due to issues with the pneumatic rod, mainly including poor-quality materials, component defects, and lack of testing.

From the perspective of structural components, office chair breakage problems often arise at the connection between the backrest and the base, as well as in the adjustment mechanisms. These areas are subjected to stress from repeated leaning and adjusting actions by the user during normal use. If the product has not passed rigorous fatigue testing, the components are prone to gradual wear and tear over long-term use. For example, micro-cracks may form at the connection points due to repeated stress, and over time, these cracks expand, eventually leading to sudden component breakage.

In terms of materials, unscrupulous manufacturers may choose thin-walled materials and low-quality connectors to cut costs. Thin-walled materials lack sufficient strength to withstand long-term use pressure; low-quality connectors may have dimensional deviations or substandard materials, resulting in loose connections that are prone to loosening and damage under repeated stress, leading to breakage. Some manufacturers may even omit key protective components, such as lacking necessary reinforcement structures or buffer devices, leaving the components without effective protection when subjected to stress and increasing the risk of breakage.

For pneumatic lift chairs, the quality of the pneumatic rod is crucial. If the pneumatic rod has a thin wall, poor material quality, uneven wall thickness of the gas spring, excessive pre-compression, insufficient purity of the filled inert gas (nitrogen), or even being replaced with compressed air, along with poor sealing at the closure, there may be a risk of explosion. When issues arise with the pneumatic rod, it may explode during normal use or when subjected to external impact, causing the office chair to break and posing a serious injury risk to the user.
