Abstract
Introduction Sitting discomfort is major health problem among the person who spent most of the time in a seated position thus it becomes necessary to study various factors that affects the sitting pressure and prevalent conditions. So that these may be neutralize or controlled in order to increase the comfort and user sitting experience. Objective The study focuses to determine the sitting pressure in three different types of contoured seat cushions and to know whether the anthropometric factors affects this sitting pressure or not. Methodology The initial interface pressure was determined by the air-inflated digital pressure meter and the left-right popliteal region and left-right ischial region pressure readings were measured among the 10 male subjects. The subjects were instructed to sit in an upright posture. Keeping the design parameters within the anthropometric limits for the structure of Chairs, they are mounted with three different types of contoured cushions. Results It was found that weight, height, and age does not proportionally and directly affect the pressure distribution on the seat pan, but the contouring of the seat affects the pressure distribution significantly. The Results were analyzed for significance test by one-way ANOVA method. Conclusion The anthropometric factors do not have any direct effect on seat pressure distribution.
