A basic philosophy in ergonomics is to design workstations that are comfortable, convenient, and productive to work at. Ideally, workstations should be designed to fit both the body and the mind of the operator. This chapter focuses on the body, which certainly is the easier of the two problems. We will demonstrate how adjustability of chairs, stools, benches, and task arrangements can help to accommodate people of different body sizes. Using anthropometric design principles it is possible for a variety of people to find physical comfort at a workstation. On the other hand, not taking these physical requirements into consideration may create bad work postures leading to fatigue, loss of productivity, and sometimes injury.
