A lifting device for headrest includes a fixing frame, a driving rod, two headrest supports, a driving device fixed on the fixing frame, and two lifting mechanisms configured on the fixing frame and located at two sides of the driving device. Each lifting device includes a reversing driving assembly, a guide rod and a slider moveably connected on the guide rod, the two headrest supports are mounted on the sliders, respectively, the driving rod passes through and is driven by the driving device, two ends of the driving rod are connected with the reversing driving assemblies, respectively, and the slider is driven by the reversing driving assembly. Both sliders on the two lifting mechanisms have driving forces so as to improve balance at both sides and make the support force stronger. The headrest is kept in a stable status, thereby preventing damage of the lifting device and the sofa.
