Unregulated Office Chair

Unregulated office chairs have various quality issues and safety hazards, mainly including component defects, inferior materials, poor stability, and excessive harmful substances.

1. Component defects causing explosion risks
Pneumatic lift swivel chairs using inferior pneumatic rods may explode due to component defects. According to a 2020 inspection by the State Administration for Market Regulation, 23.3% of office chairs failed the inspection, with 17 batches being swivel chairs. The main issues included substandard high- and low-temperature resistance of the pneumatic rods and the absence of explosion-proof steel plates. As the core component for adjusting seat height, if the pneumatic rod lacks sufficient pressure resistance, sealing, or material strength, it may rupture under high or low temperatures or frequent lifting, causing the sudden release of high-pressure gas inside and triggering an explosion. The explosion-proof steel plate is designed to block fragments produced during a pneumatic rod explosion. If not installed or installed improperly, it significantly increases the risk of injury to the user.

2. Inferior materials causing health hazards
Unregulated office chairs may use black-hearted scrap materials as fillers or covering materials, such as recycled plastics, low-quality sponges, or formaldehyde-containing adhesives. These materials may release volatile organic compounds (VOCs), such as formaldehyde and benzene. Long-term exposure can irritate the respiratory tract, eyes, and skin, and even increase the risk of cancer. Additionally, inferior materials are prone to deformation and collapse, failing to provide sufficient support and leading to health issues such as back pain and neck fatigue in users.

3. Poor stability causing tipping risks
Some unregulated office chairs have design or manufacturing defects that result in insufficient stability. For example, a base that is too light, poorly secured casters, or an unreasonable backrest structure may cause the chair to tip over when leaning forward, backward, or sitting sideways. Additionally, unqualified caster wear resistance can affect the chair's lifespan, causing the wheels to jam, fall off, or slide poorly, further increasing the risk of tipping. These issues are particularly prominent among children or heavier users.

4. Excessive harmful substances threatening health
Excessive formaldehyde emissions are a common issue with unregulated office chairs. Formaldehyde is a colorless gas with a pungent odor, commonly used in panels, adhesives, and coatings. If formaldehyde content is not strictly controlled during production or inferior raw materials are used, the formaldehyde emissions from the office chair may exceed national standards (e.g., ≤0.124mg/m³ as specified in GB 18580-2017). Long-term exposure to high concentrations of formaldehyde can cause headaches, dizziness, and a weakened immune system, and even increase the risk of serious diseases such as leukemia.
