Abstract: A tunnel cord assembly for removably attaching a trim cover to a contoured, cellular foam pad is comprised of a selvedge strip slidably encasing the cord and a bayonet-type fixture at the ends of the cord. The selvedge strip is sewn to the trim cover, which attaches to the foam pad. The foam pad includes a front surface, an opposite back surface, a plurality of trenches and a plurality of holes within the trenches. Each end of the tunnel cord is pulled through a hole that extends through the foam pad from the front surface, which is covered by the trim cover, to the back surface. A locking device is then removably coupled between the back surface of the foam and the bayonet-type fixture, preventing the cord from retracting through the hole back to the front surface of the pad, and thereby securing the trim cover to the foam pad.
