As described in the “Foam Stress Strain Resilience” study foams are sold based PSI metrics which are rarely relevant to the complex applications in which foams are used. This study introduces several new metrics that can be extracted from a customized relaxation and creep recovery test. It illustrates the metrics by testing the same foam samples - the Firmness Selector pack which contained eight foams and the Material Selector pack which contained different 13 foams.
