Development History

The office chair originally evolved from the Windsor chair. Thomas Jefferson transformed it into a swivel chair, facilitating flexible rotation during office work. Charles Robert Darwin added wheels to the office chair, further enhancing its mobility. Thomas Warren invented an office chair in 1849 that could rotate, slide, and had a spring-loaded seat, making the functions of the office chair more comprehensive.

Structure and Materials

• Structure: Composed of eight basic components, including wheels, a five-star base, a gas lift, and a chassis. Among them, the gas lift is the core component for adjusting the seat height. It controls the rise and fall of the seat through changes in air pressure to meet the needs of different heights and usage scenarios.
• Materials: Common materials include leather and mesh. Leather models are mostly made of PU leather or genuine leather. These office chairs usually have a more upscale appearance and are mainly used for executive chairs and mid-level chairs. Mesh models, due to their good breathability, are commonly found in junior chairs, especially suitable for summer use, allowing users to stay dry and comfortable during long hours of office work.
