Abstract
A chair base is revealed. A round bulge is formed on a center of a bottom surface of a bottom plate and a limit portion is gradually flattened from the round bulge toward a periphery of the bottom plate. A base body is disposed on a top surface of the bottom plate while a cover is used for covering the base body therein and enclosing the periphery of the bottom plate. Thereby the bottom plate, the base body, and the cover are connected and fixed by one another. While in use, users rock the chair by the round bulge on the bottom plate in response to their shifts in center of gravity. A rock angle of the chair is limited by the limit portion. Thereby the users will not tip the chair over while rocking the chair violently and safety in use is ensured.
