Abstract
A vehicle seat includes a seat base, a seat foam supported by the seat base, and a support pad positioned between the seat base and at least a portion of the seat foam. The support pad being formed of a combination of a first material and a second material. A seat cover covering the support pad and the seat foam. The first material has a first recovery hysteresis and the second material has a second recovery hysteresis that is less than the first recovery hysteresis.
