Application Instructions

Thread each of the straps with the quick release buckles through available openings in the perimeter of the movable section of the bed frame.

Defined Perimeter CoverSecure the end of the quick-release buckles and tighten the straps securely. This allows the cover to remain in placec as the entire bed, head section, or foot section is raised/lowered. Avoid areas where straps may interfere with the lowering and raising mechanism of the bed. 

Removable foot bolsterIf using a sheet, attach the eight sheet clips, located on the quick- release buckles, to the sheet (Fig. 2). If desired, attach the foot bolster (Fig. 3) to the mattress cover using the attached Velcro.
