A swivel assembly for use with a chair has a swivel that includes an actuator which biases and self-centers the swivel to a start or zero position wherein the swivel is rotated from its start or zero position in either a clockwise or counterclockwise manner to an alternate position. When the swivel is released the actuator biases the swivel back to its start or zero position. A method for self-centering swiveling of a chair includes providing a swivel that has an actuator which self-centers and biases the swivel to a start or zero position; rotating the swivel from its start or zero position, thus compressing or tensioning the actuator; and releasing the swivel thus moving the actuator to bias and rotate the swivel back to its start or zero position.
