As time spent in our vehicles increases, requests for automotive seat comfort have also increased. In particular, extended seat use typically causes the seats foam pad to sag or distort. Therefore, this study develop a new seat foam pad by applying different evaluation specifications, such as two different harness specifications and hysteresis loss rate. Based on the new specifications, a new seat foam was verified with three tests ? harness, force-deflection, and compression ? that compared it a sagging, uncomfortable foam pad. Finally, the newly developed foam pad with applied enhanced specifications proved that it offers better performance than the pad originally issued in the vehicle.
