Abstract

A seat cushion body and method of producing the same are provided. In a method of producing a seat cushion body, fiber material is inserted into a mold. Heat is supplied to the fibers to cause thermal activation of binding fibers, so as to effect thermal cross-linking. The resulting seat cushion body includes a resilient portion formed from the fibers and having a fiber orientation along a main load direction of the seat cushion body. The seat cushion body may include at least one further portion formed from the fibers, which has a fiber orientation and/or a density different from the fiber orientation and/or different from a density of the resilient portion. The resilient portion and the at least one further portion may be integrally formed from the cross-linked fiber material as a unitary body.
