Technical Field

The utility model relates to the technical field of office furniture, in particular to an adjustable conference chair.

Background Art

However, conference chairs are also called guest chairs. As the name suggests, they are a kind of furniture used by people during meetings or conferences at work. They can be divided into solid wood, bent wood, steel and wood, mesh and plastic. Conference chairs are often related to major company events, such as business negotiations or internal decision-making. They are places that represent the company's image, so the role played by conference chairs is particularly important.

The backrest of the chair is designed to make people more comfortable when sitting, but the armrests on both sides of the chair also affect the comfort of the chair. However, the height of the armrests of conventional chairs is fixed and cannot be adjusted, which makes the comfort of participants when using conference chairs insufficient.

A further technical solution is that a writing board is hingedly connected to one of the armrests, a connecting rod is fixedly connected to the bottom of the writing board, and a limiting plate is rotatably connected to the bottom of the connecting rod.

A further technical solution is that a handle is fixedly connected to the bottom end of the control rod.

A further technical solution is that the support leg is arranged in a "匸" shape and is thickened at the left bend.

A further technical solution is that sponge pads are fixedly installed on the top surface of the seat and the side surface of the backrest close to the seat.

Compared with the prior art, the beneficial effects of the utility model are:
