The folding office chair refers to the chair that the person sits when performing the desktop work in the sitting state, and is broadly defined as all the chairs used for the office training room, including the conference chair and the training chair. The training chair is equipped with a P-shaped writing board on the right-hand side when the person sits down and can record when training or meeting. The mainstream tablet is now divided into a plastic writing board and a tablet writing board; the bottom of the chair is equipped with an iron book basket.
