Reasons for Broken Office Chairs

There are various reasons why office chairs become 'broken' or damaged, including long-term wear and tear, quality issues, component damage, and inferior materials.

1. Wear and Tear from Long-Term Use
   After prolonged use, the support frame of the backrest in ergonomic chairs may fracture due to metal fatigue or material aging. For example, the metal or plastic frame of the backrest may gradually deteriorate under repeated stress, eventually leading to breakage. Simultaneously, the surface fabric or foam may become indented and lose elasticity from prolonged pressure, resulting in reduced support. This type of wear is typically directly related to the frequency and duration of use and is considered normal aging.

2. Sudden Damage Due to Quality Issues
   Some office chairs may suddenly break during use due to manufacturing defects or substandard materials. For instance, if the gas lift in a swivel-lift chair is of poor quality, it may burst due to abnormal internal pressure or seal failure, causing metal fragments to fly and potentially injure someone. Such incidents are often related to the material, manufacturing process, or service life of the gas lift and can be mitigated by choosing reputable brands and conducting regular inspections.

3. Functional Abnormalities Caused by Component Damage
   If an office chair tilts to one side or cannot move properly, it is usually due to component damage. For example, the wheels may become damaged from prolonged rolling or getting stuck with foreign objects, making the chair difficult to move or causing it to tilt; uneven floors may exacerbate uneven wheel stress, further accelerating damage. Additionally, if the connectors (such as screws or hinges) beneath the seat plate become loose or break, the seat plate may tilt or sink, affecting stability.

4. Rapid Damage Due to Inferior Materials
   Some internet-famous or low-priced office chairs may use inferior materials to reduce costs. For example, 'slippery stools' have been exposed for using moldy wood, recycled foam, or recycled plastic. These materials not only lack strength but may also contain harmful substances. Moldy wood is prone to rot, recycled foam is prone to collapse, and recycled plastic is prone to brittleness, all leading to structural damage or safety hazards in the short term.

Summary: The causes of office chair damage encompass design, materials, usage, and maintenance. To extend their service life, it is recommended to choose products from reputable brands, regularly inspect key components such as gas lifts and wheels, avoid overloading, and promptly replace aged or damaged parts.
