ABSTRACT:
A fastener assembly of the type for being molded into cushions, and including a base having first and second major surfaces defining first and second opposed ends and first and second opposed side edges. A multiplicity of attachment members are carried by the base and extend outwardly from the base for cooperating with complementary attachment members. First and second laterally ending sealing gaps are respectively positioned adjacent the ends of the base. The sealing gaps are defined by areas of the first major surface of the base being devoid of the attachment members for permitting a sealing dam carried by a mold in which the foamed article is molded to fit into the sealing gaps and sealingly engage the first major surface of the base to form a foam-tight seal between the opposed ends of the base and the sealing dam of the mold to prevent intrusion of liquid foam past the ends of the base onto the attachment members of the base during molding of the article. A multiplicity of permanent anchors is carried by the base and extend outwardly from the second major surface of the base. First and second magnetically-attractable side edge sealing members may be attached to the base adjacent respective ones of the first and second opposing side edges of the base for being attracted to magnets positioned in the mold in which the foamed article is molded to form a foam-tight seal between the side edges of the base and the mold to prevent intrusion of liquid foam past the side edges of the base onto the attachment members of the base during molding of the article.
