Office Chair Breakage

Admin October 09, 2026

Office chair breakage can be caused by various factors such as structural failures, improper use, aging and wear, or floor issues.

Structural failures: Some inexpensive computer chairs have unstable five-star base designs or components like casters and gas cylinders that are not strong enough, making them prone to imbalance under load. For example, if the gas cylinder's seal fails, it can lead to abnormal lifting and lowering functions, causing the chair to lose balance and fall. Similarly, if the casters are not strong enough, they may break during movement, destabilizing the chair.

Improper use: Frequent and violent rocking of the chair, standing on it alone, or multiple people using it simultaneously can exceed the chair's weight capacity, leading to breakage. Office chairs have specific design load standards, and exceeding these standards puts excessive pressure on the chair's components, accelerating damage.

Aging and wear: After prolonged use, various components of an office chair will experience different degrees of aging and wear. If the gas cylinder's seal fails, internal gas leakage can affect the chair's stability. If the casters fall off, the chair becomes difficult to move and prone to tipping. A deformed five-star base can alter the chair's center of gravity distribution, and loose screws causing connection failures can also make the chair structurally unstable, all of which can lead to breakage.

Floor issues: Uneven floors, such as tile gaps or carpet bulges, can cause the casters to get stuck, preventing the chair from moving normally and leading to falls. Placing the chair on a slope or smooth surface can also cause it to lose balance and fall due to an unstable center of gravity.

In addition, office chair breakage can also lead to work-related injuries. If an office chair breaks and causes a fall during working hours and at the workplace, and the incident is directly related to work, it should be recognized as a work-related injury, and employees are entitled to corresponding work-related injury benefits. For example, a consumer complained that the Sihoo B100Pro ergonomic chair they purchased suddenly lost balance and fell after less than half a month of use, which could be the result of a combination of the above factors.
