Abstract
A chair with a chair back having a frame and a backrest. The backrest is connected to a bottom frame portion of the frame and two side frame portions at two opposite ends of the bottom frame portion by injection molding for a user to lean against. A hardness of the backrest is lower than a hardness of the frame, and the frame is provided with two supporting portions for correspondingly supporting two sides of the user's waist. Thereby, the components with different hardness are capable of forming the integrally formed chair back, and enabling the chair back to be both supportive and comfortable for leaning against.
