A pillow lifting structure includes a bottom plate. The bottom plate is provided with a power unit. The power unit is connected to a linking unit. The top of the linking unit is covered with a cover. The power unit actuates to deform the linking unit for adjusting the height of the cover in time so as to adjust the height of the top surface of the pillow. The X-shaped linking unit of the pillow lifting structure is lifted by a driven arcuate gear with a push arm. This action is a direct push, and there is no power consumption. Only a small motor is required for actuation. Space and energy consumption are optimized by the direct push.
