ABSTRACT
This chapter discusses the ubiquitous term ‘comfort’ by analysing a biomechanical correlate to sitting comfort; that is the pressure distribution between the seat surface and its occupant. A variety of approaches can be used to measure the pressure distribution. The widespread use of computers has been accompanied by a heightened interest in the ergonomics of office seating. In addition to improving the wellbeing of the worker, a comfortable seat may contribute to productivity. A well-designed seat should fit all sizes and shapes of users. Size differences may be accommodated through adjustability. Many designers view sitting as a static activity and design seats based on anthropometry. The H-point machine is one which has a seat back and seat pan representation of a deflected seat contour for adult males. This machine simulates the human torso and thigh and is mechanically articulated at the H-point.
