Office Chair Professional Terms

Professional terms related to office chairs cover multiple fields such as functionality, structure, usage scenarios, industry terminology, and historical development. The specific classifications are as follows:

Classification by Function

1. Office Swivel Chair (Pneumatic Swivel Chair): Centered around a pneumatic lifting system, it supports rotation and height adjustment, commonly found in modern office settings. Its core components include a seat cushion, backrest, five-star base, casters, and a pneumatic rod.
2. Ergonomic Swivel Chair: Maintains the body's natural physiological curves through adjustable lumbar support, armrests, and headrests. Functions include seat height, backrest angle, seat depth, armrest height, and angle adjustments to accommodate different body types.
3. Dynamic Support Technology: Includes dual dynamic lumbar support, flexible back-following design, and domino three-dimensional lumbar support systems, achieving dynamic lumbar fitting through elastic materials or mechanical structures to enhance long-sitting comfort.

Classification by Structure

1. Core Components: Casters (mobility function), chair base (support structure), gas rod (pneumatic rod for height adjustment), chassis (connecting component), seat (wood/foam/fabric layer), armrests, backrest, lumbar pillow, and headrest.
2. Material Types: Genuine leather, PU leather, fabric, mesh, and plastic office chairs. Among them, mesh chairs use high-elasticity materials to enhance breathability and heat dissipation, while waterfall curve seat cushions reduce leg pressure through front-end downward tilt design.
3. Special Designs: Such as adjustable headrests, breathable mesh back panels, and modular assembly structures to meet personalized needs.

Classification by Usage Scenarios

1. Executive Chair: High backrest design, standard with armrests, suitable for management offices.
2. Mid-back Chair and Staff Chair: Low backrest or armless design, space-saving, commonly found in open office areas.
3. Specialized Chairs: Such as drafting chairs (with footrest rings), conference chairs (lightweight and foldable), and bar stools (high-leg design), optimized for specific scenarios.

Industry Terminology

1. Pneumatic Rod (Extension Rod): A key component for seat height adjustment and rotation, must comply with safety standards to avoid explosion risks.
2. OEM Model: Since 2000, China's office chair industry has developed through original equipment manufacturing (OEM), with Anji County in Zhejiang Province becoming a major global production base, leveraging cost advantages to dominate the international market.
3. Intelligent Trend: Integrates pressure sensors, health monitoring (such as heart rate detection), and APP control functions, driving product upgrades towards health management.

Historical Related Terms

1. Centripetal Spring Chair: Invented by Thomas Warren in 1849, it was the first to combine rotation, sliding, and an elastic soft seat surface, laying the foundation for modern office chairs.
2. Windsor Chair Modification: In 1775, Thomas Jefferson connected two seat surfaces with an iron shaft and pulleys, achieving upper-part rotation function, reflecting early ergonomic exploration.

Other Related Terms

1. Headrest: As a key component for comfort, its height and angle adjustability directly affect neck support effectiveness.
2. Environmentally Friendly Chair: Uses recyclable materials or low-volatile coatings, but domestic development remains insufficient due to immature technology.
3. Recall Incidents: Safety hazards caused by design flaws (such as gas rod quality) or manufacturing defects prompt the industry to strengthen safety standards.

The above term system covers the full chain of professional expressions from office chair design to application, providing reference for industry research, product development, and consumer purchasing.
