We established a posterior characteristics index (PCI) to quantitatively evaluate static seating comfort of motorcycle seats. This index expresses such characteristics as the shape and size of the posterior as well as the weight of a person. The static seating comfort of motorcycle seats was analyzed using the PCI and seated body pressure distribution data.As a result, it was found that the contact surface area and level of surface area change in the body pressure distribution data obtained while the test subject was seated are effective indices for static seating comfort common to all test subjects.
