An apparatus for supporting a patient includes a frame, a patient support deck coupled to the frame and configured to support the patient, and a head rest coupled to the patient-support deck and having longitudinally-extending, transversely spaced-apart sides. The head rest includes a pair of longitudinally-extending, transversely spaced-apart socket tubes adjacent to respective head rest sides. The head rest also includes a bottom plate extending transversely between the socket tubes and a side plate angling upwardly from each of the socket tubes so that a head cushion-receiving space is defined between the side plates. Each of the socket tubes has an interior region adapted to receive portions of a wrist rest assembly configured to be coupled to the head rest.
