A patient support device includes an alternate support top, a head support unit partially supporting the alternate support top, a foot support unit longitudinally spaced from the head support unit and an adaptor associated with the foot support unit. The adaptor is securable to the foot support unit so that the adaptor and foot support unit cooperate to partially support the alternate support top so that the alternate support top extends footwardly beyond the foot support unit. The roles of the head and foot suppport units may be reversed. A related patient support system includes a baseline set of support tops and a set of alternate support tops.
