ABSTRACT:
A multi-stage backrest assembly for a chair includes a support frame, a back support mounted on the support frame, a head support mounted on the support frame, and a waist support pivotally mounted on the back support. Thus, the backrest assembly has a pivotable function so as to fit the curve of the user's body ergonomically, thereby providing a comfortable effect to the user. In addition, the locking tube of the crossbar of the back support is adjustably mounted on the respective support rod of the support frame, so that the back support is adjustably mounted on the support frame to adjust the height of the back support so as to fit users of different statures.
