1. A method of providing a support surface for a patient, the method comprising the steps of:
forming a foam frame defining a space;
positioning a bladder assembly in the space;
enclosing the foam frame and the bladder assembly in a cover, the cover adapted to engage an articulated frame to control movement of portions of the foam frame and the bladder assembly in response to movement of the articulated frame;
securing a first protrusion to the foam frame, the first protrusion extending from a bottom surface of the cover and adapted to be received in a first receiver formed in an articulated frame of a patient support apparatus to secure the foam frame to the articulated frame; and
securing a second protrusion to the bladder assembly, the second protrusion extending from the bottom surface of the cover and adapted to be received in a second receiver formed in the articulated frame of the patient support apparatus to secure the bladder assembly to the articulated frame.
