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.

Abstract: Embodiments of the present disclosure relates to the field of furniture. Provided is a sofa seat stretching device. In the sofa seat stretching device, one end of a second support facing away from a first support, and a second leg rest plate connector are hinged at a fourth hinge point, so that the stretching assembly's stretching speed is reduced in a process of switching from a sitting position state to a lying position state when a driving assembly acts in the same way, and the weightlessness feeling can be effectively avoided. Moreover, the driving assembly drives the stretching assembly so that the process of switching the stretching assembly from the lying position state to the sitting position state is smoother.
