A patient support apparatus generally includes a base frame and a support deck supported on the base frame, the support deck comprising a seat portion. A segmented patient support surface is slidably coupled to the support deck. A lift system is coupled to the support deck and the segmented patient support surface. The lift system raises, lowers and tilts the support deck with respect to the base frame, and pivots a torso support segment of the support surface with respect to a leg support segment of the support surface. A foot plate assembly is removably positioned proximate a free end of the support deck, the foot plate assembly receiving a patient's feet when a patient is positioned on the segmented patient support surface thereby enabling the patient to slide the segmented patient support surface relative to the support deck.
