Video: 'The Office Chair You Sit on Every Day Is Actually a High-Pressure Bomb That Could Explode at Any Moment...'
This video focuses on the potential safety risks of adjustable-height chairs, highlighting the dangers of gas spring explosions. The core component of an adjustable-height chair is the gas spring, which is filled with high-pressure nitrogen gas. If the gas spring is of substandard quality (e.g., made from inferior materials, has poor sealing, or is used beyond its lifespan), it may explode due to gas leakage or temperature changes, causing a sudden increase in internal pressure. During an explosion, the metal casing of the gas spring can fly out at high speed, causing serious injuries such as cuts and punctures to the user. The video reminds users to avoid purchasing unbranded products, regularly inspect the appearance of the gas spring (e.g., for cracks or air leaks), and replace adjustable-height chairs that have been in use for more than 5 years promptly.
Video: '...+ Explosion-Proof Chassis, Four-Level Gas Spring for Safety and Stability, Choose This for Your Office Chair'
This video uses the Henglin L700 ergonomic chair as an example to introduce the design standards for safe office chairs. The explosion-proof chassis is a key safety device that uses thickened steel plates or high-strength engineering plastics to withstand the impact force of a gas spring explosion and prevent metal fragments from flying out. The four-level gas spring undergoes stricter pressure testing and sealing processes to minimize explosion risks while providing a more stable lifting experience. Additionally, the separate waist and back design helps distribute body pressure, reducing fatigue from prolonged sitting and indirectly lowering the risk of operational errors caused by physical discomfort. The video suggests that users choose products certified by BIFMA (Business and Institutional Furniture Manufacturers Association) or GB/T (Chinese National Standards) and prioritize purchasing office chairs equipped with explosion-proof chassis and four-level gas springs.

This video systematically reviews common hazards associated with office chairs, in addition to gas spring explosions, including:
- Loose Structure: After prolonged use, components such as screws and wheels may become loose, leading to chair tipping or uncontrolled sliding.
- Material Aging: Plastic parts and foam cushions may deform due to UV exposure or high temperatures, reducing support and stability.
- Design Flaws: Issues such as unreasonable backrest angles or non-adjustable armrest heights may cause lumbar muscle strain or cervical spine problems.
The video emphasizes the importance of regularly inspecting all components of the office chair (monthly), avoiding overloading (generally limited to 100-120 kg), and immediately discontinuing use and contacting after-sales service if any abnormalities are detected.
