    Abstract: A stanchion with enhanced stability and user safety is provided. The stanchion includes a base having a top surface, a bottom surface and a central opening extending from the top surface to the bottom surface, the central opening in the base having an inner surface with a locking protrusion coupled thereto, and an elongated body with a bottom end rotatably mounted to the central opening of the base and having a pair of tabs. The elongated body is designed to rotate to a first position to permit one of the pair of tabs to engage with the locking protrusion on the base, thereby locking the elongated body to the base. The elongated body is designed to rotate to a second position with the pair of tabs disengaged from the locking protrusion on the base, thereby unlocking the elongated body from the base.
