An operator seat for a work vehicle is disclosed. The operator seat includes an operator support rotatably mountable to the work vehicle and an arm coupled to the operator support to rotate with the operator support. The arm includes at least one human-machine interface device. The operator seat includes a hinge pivotally connecting the arm to the operator support, and a linkage having a first end and a second end. The first end is coupled to the operator support, and the linkage is configured such that rotation of the operator support in a first direction causes the second end of the linkage to move the arm in a second direction substantially opposite the first direction.
