ABSTRACT:
First and second clamshell-shaped foam members are mated, the first and second foam members meeting along exteriorly exposed joint margins defined by mateable surfaces extending along opposite sides of each of the members. At least one other foam member is nested totally within the mated assembly of the first and second members and nested without joint margins exposed to the exterior of the mated assembly. The surfaces enclosed within the mated assembly pilot the first, second and other members into mating relationship. The first and other members are adhesively bonded together and the second member is adhesively bonded to the assembly of the first and other member.
