Abstract

A foam seat element comprising an isocyanate-based foam matrix having an A-surface for contact with an occupant and a B-surface for contact with a suspension element. An elastomeric layer is disposed on at least a portion of the B-surface for contact with the support element. This approach results in reduction in labor to produce the elastomeric layer compared with correct positioning of cloth inserts on a foam production manufacturing line. Further, since, in the preferred embodiment of the invention, the elastomeric layer is achieved by spraying a liquid elastomer-forming composition on a portion of the mold surface, the costs of achieving the elastomeric layer are significantly less than those associated with using prefabricated, pre-cut cloth inserts. Still further, the use of an elastomeric layer allows for tuning of the thickness of that layer which facilitates 'tuning' the durability of the B-surface of the foam seat element based on the specific suspension system with which it will be combined.
