Abstract
Various kinds of upholstered chairs are used appropriately for the purposes and the scenes in the daily life. The seating comfort of the chair is the most important matter. Many factors, such as the texture of seat surface, the width and the height of the chair, the cushioning of the seat surface and the back support, are related to the seating comfort. The upholstering fabric is considered to be an important factor among them. The purpose of this research is to clarify the factors which decide seating comfort by reviewing the mutual relations among seating comfort, the sensory tests and the physical properties of the upholstering materials. The following results were obtained. (1) The warm-cold sense, the softness sense and the sweat sense of handling feel were correlated strongly to the seating comfort. (2) The sweat sense of the seating and handling feel and moisture regain of the upholstering material were not correlated to the seating comfort. (3) The seating comfort can be 90% evaluated in the warm-cold sense and the softness sense of the handling feel by the multi-regression analysis
