The square chair base plate includes a central cylindrical socket, a long metal control lever, and a black metal mechanism mounted on the top face for integrated operation. Four slotted holes near the corners make this chair base plate easier to align during installation and secure beneath the chair seat. As a swivel chair base plate, it serves as the lower support component that helps keep the chair assembly stable and functional in everyday use.
