The seat is perhaps more closely linked to operator comfort and feeling of well-being than any other machine component. This is because a good operator seat performs the following basic functions (Koutsky, 1978):
Therefore, the interfacing of the human operator to a machine - the biological to the mechanical - requires special considerations involving many aspects of human factors engineering and machine design in general. The subject is much too broad to be covered in detail in this paper. I shall attempt to outline some of the important considerations in seat design and evaluation, and reference other sources of more detailed information which should be helpful, especially to the engineer starting to work in this area for the first time.
