Abstract
A sofa armrest folding mechanism and a sofa armrest are provided. The sofa armrest folding mechanism includes: side boards, a handle, and folding devices, where the side boards are connected to two sides of the folding devices, respectively; two ends of the handle are connected to top ends of the folding devices, respectively; the folding devices switch between a folded state and an unfolded state through the handle; when the handle is pulled upwards, the folding devices are in the folded state; and when the handle is pushed downwards, the folding devices are in the unfolded state. Connecting teeth on each two adjacent connecting rods are engaged, and the handle is pulled upwards or pushed downwards to drive the side boards to move close to or away from each other, achieving a change in the overall structural state.
