Abstract
The present invention relates to a seat frame, including a lower base; an upper base; and a plurality of rotating devices disposed on the upper base or the lower base and including at least one rotating device capable of horizontally rotating the lower base relative to the upper base. The lower base is connected to the upper base. When the rotating devices make the lower base horizontally rotate relative to the upper base, the upper base and the lower base do not fall off each other. A plurality of connecting devices are disposed on the upper base. The present invention eliminates the noise generated in the rotating process; and a telescopic support enables the size of the seat frame to be adjustable, the installation is simple and convenient, the use effect is good, and it is more stable and is suitable for popularization.
