Abstract

Literature on seat comfort recognizes that seat interface pressures are the objective comfort measures that most clearly relate to users’ comfort perceptions about sitting experience. In this paper, the above relationship is quantitatively investigated by performing simple but effective explorative analyses on seat comfort data collected during experimental sessions involving 22 volunteers who tested 4 office chairs (differing in terms of cushion softness). Statistical data analyses show that subjective sitting comfort/discomfort ratings are significantly related to several combinations of pressure variables. The joint analysis of synthetic indexes based on seat interface pressures reveals to be a useful tool for comparative seat comfort assessment. Besides valuable suggestions for the definition of an effective strategy for seat comfort assessment, the results of data analyses provide useful information to support the product design phase. In fact, the sitting experience results to be significantly improved by: (1) a balancing of pressures between the bilateral buttocks; and (2) a balancing of contact areas between buttocks and thighs.
