perceived comfort and the WPCL index cannot be rejected. However, from an engineering
standpoint, the final seat rating evidences substantial coherence of peak pressure and
WPCL index, showing not redundant results useful to design team for seat comfort
improvement. Since results were strongly influenced by experimental conditions and
anthropometric variability of the experimenters, further investigations should be carried
out. On the basis of the first experiments, a refinement of the index and new test
conditions could be investigated.
