Application of a method for evaluating moisture transfer characteristics of chair seats to bedding

Abstract

This study aims to improve our method, which was designed to evaluate the moisture vapor retention performance of chair seat, for applying to bedding. Since body pressure distribution is much wider when sleeping, it is desirable to improve the method to make it possible to evaluate the effects of differences in load as well as material. An experiment was conducted to measure the surface humidity under six combined conditions involving two materials and three levels of loads.
