A medical bed for positioning the patient in the lithotomy position having a mattress pad including a flexible footrest section. The footrest section cascades over and down an end of the medical bed as the mattress pad is translated, or slid, toward the end thereof. The mattress pad is positioned atop the frame, and includes a backrest section, a medial section, and a footrest section. The mattress pad is translatable, or slidable, with respect to the frame. The footrest section includes a plurality of partitioned segments that are pivotable with respect to each other such that the footrest section cascades down and over the foot-end of the frame when the mattress pad is translated toward the foot-end of the bed.
