Abstract

Disclosed is a chair, comprising a back of the chair (2) and a seat of the chair, wherein the back of the chair (2) is arranged in an arc-shaped manner, with the arc-shaped protrusion of the back of the chair (2) facing towards the side of the seat of the chair. When a person sits and their back bends backwards in an arched position, the back will be blocked by the arc-shaped protrusion of the back of the chair, so as to keep the human body in a more upright sitting posture and be more comfortable. Thus, a person who sits for a long time will not be tired, and the seat is especially suitable for a person who need to sit in a chair for a long time to work. However, the directors chair used currently is still a traditional back of a chair. The back of the chair sinking backward leads to the back being bent for a long time, and thus being very tired. However, adopting a chair with the back of the chair protruding toward the seat of the chair in an arc-shaped manner can avoid this problem, avoid the back of the chair from sinking backward, and keep the human body in a more upright sitting posture.
