ABSTRACT:
Composite shaped foam articles of manufacture and method for fabricating such articles is disclosed. The articles are formed by providing a section of foam material, treating a first surface of the section of foam material with adhesive, providing a second section of flexible foam having a surface to be joined with a surface of the first section, treating at least one of the surfaces to be joined with a suitable adhesive, joining the treated surfaces of foam, deforming the joined sections of foam into a selected shape, and curing the adhesives whereby the joined sections of foam remain elastically deformed rather than restoring to their original unstressed condition thus maintaining their selected shape.
