ABSTRACT:
A bedding foundation is manufactured with a cover having a welt cord extending upwardly to create a seal when a mattress is placed on the foundation. The cover is made using a two stage process. During the first stage a sewing machine is used to join a welt cord to a web of border material. In the second stage a second sewing machine sews a piece of non-skid decking to the border assembly. Fullness may be incorporated into the border material to enable the cover to fit around the corners of the bedding foundation with the welt cord being spaced inwardly from the perimeter of the foundation.
