A patient support apparatus comprises a litter and a base configured to receive and support the litter when the litter is docked to the base in a docked state. A foot end extension is coupled to a foot end of an intermediate frame of the base, with the foot end extension defining an extended position wherein at least a portion of the foot end extension extends outwardly beyond the foot end of the litter in a direction opposite the head end of the intermediate frame when the litter and base are in the docked state. The foot end extension includes a top surface that is axially aligned with a substantially flat configuration of the litter in the extended position. The foot end extension can be fixedly coupled in the extended position or movably coupled to the intermediate frame and movable between the extended position and a non-extended position.
