Abstract

An ergonomic chair includes a back component and a seat component. The back component includes an upper back support, a lower back support, a seat back frame that is elastically deformed under traction or squeezing, and a locking mechanism for maintaining positions of the above three components to be relatively fixed. The lower back support is connected to the seat component through a connecting rod. A lower end of the upper back support is rotatably connected to an upper end of the lower back support. Upper and lower ends of the seat back frame are respectively hinged on an upper portion of the back support and the lower portion of the lower back support.
