The pressure distribution between human body and seat surface has been considered as an important factor affecting seating comfort. However, it is rare to find general guidelines of how to analyze these pressure patterms related to the seating comfort. In order to investigate the relationship between the pressure patterns and the subjective feeling of seating comfort, a high-resolution body pressure measurement system was adopted. The measured patterns showed that the clear distinctions between the comfortable seats. It was also possible to estimate the seating comfort based upon the analysis of the pressure patterns. The further research will be focused on finding out the relationship between physical seat design parameters and the seating discomfort.
