Effects of Aging of Polyurethane Foams in the Context of Furniture Design

An ergonomic seat or bed must be capable of supporting optimally and evenly the user’s body for sustained periods of time. The objective of the performed nvestigations was to ascertain the impact of natural aging on the stiffness of polyurethane foams in dwelling apartment conditions and, additional...
