A movable base for a shade structure such as an umbrella that is operable between a movable configuration and a braked configuration. The movable base includes a first frame, including a plurality of wheels, such as caster wheels, and a second, e.g., movable, frame that is actuatable relative to the first frame and wheels. In the movable position, a plurality of feet are raised and the wheels are in contact with a ground surface. In the fixed position, the feet of the second frame are in contact with the ground and/or the wheels are raised.
