ABSTRACT
One of the key elements in ensuring that people can work comfortably and effectively is good posture. There is some controversy regarding what constitutes “good posture.” The traditional view is that an upright posture is the most appropriate. The chapter provides an understanding of what can assist in creating a comfortable working posture. There are benefits to sitting over standing: people can take the weight off their legs; greater stability is offered to the upper body; energy expenditure is reduced, as are demands on the circulatory system. A person who is required to stand for prolonged periods can experience physiological changes including peripheral pooling of blood, a decrease in stroke volume, and increase in heart rate. Once the seated height is established and properly supported, the focus should turn to the back and the degree of support offered by the backrest of the chair.
