Abstract
Provided are a chair frame and a chair. The chair frame supports a human waist and back by using a waist support assembly and supports human legs and feet by using a footstool assembly. Meanwhile, when the waist support assembly is unfolded, driven by a second support rod, a second end of a first support rod can swing toward the footstool assembly with a junction between a first end of the first support rod and the second support rod as a rotation center to increase an included angle between a waist support bracket and a seat cushion bracket, that is, increasing an unfolded angle of a backrest and achieving the zero gravity effect. The chair can improve the chair comfort by applying the preceding chair frame.
