Abstract: A system including a footboard and a chock each adapted for secure, yet easily removable attachment at selected locations to the patient support surface of a mattress on an elevating head type bed is provided. The footboard and the chock both include a wedges of resilient material having a substantially planar base surface and a length dimension substantially equal to the width dimension of the patient support surface. The footboard wedge also defines a foot support surface normal to its base surface. The chock defines an upwardly extending curved surface between the forward and rear edges of its base surface. The footboard and the chock further respectively include support members extending along the length of the wedges. Attachment means for affixing the footboard and the chock respectively to the patient support surface extend around the mattress portion of the bed between the opposite side edges of the base surfaces.
