Abstract
The purpose of this study was to develop systematic methods for evaluating the suitability of a seat and building an empirical model for predicting the suitability of a seat. We uncovered six dominant suitability dimensions for the design of a comfortable seat that is related to the physical dimension of a body. Here, six suitability dimensions were identified as the dimensions representing the human sensitivity and psychological feeling on comfortable seats. Also, 43 human-interface elements such as seat height, seat surface etc. were established for evaluating seat comfort. In this study 63 subjects participated in evaluating six suitability dimensions for 52 different seats. The model for evaluating suitability was also developed.
