How many years has the traditional office furniture industry developed?

I don't know whether you are talking about the domestic situation or the international situation.

If we look at the whole development history, from personal office to open office, from personal work to team work, from fixed seats to mobile office, from craftsman technology to mechanical mass production, from traditional furniture to systematic furniture, these changes of office furniture can be summarized as follows:

From about 1900, office furniture began to flourish, and later many well-known manufacturers developed from this stage. In the1960s, open office furniture was widely used in office planning.

In 1980s, the new design concept subdivided the system into subsystems, which swept across North America and Europe and affected Japan and Taiwan Province Province.

In China, the output value of office furniture industry exceeded 50 billion in 1999, and in 2000 it exceeded 100 billion. Generally speaking, the office furniture market has great potential and is an influential industry in various industries in China.

I hope my answer can help you.
