The Ergonomic Perspectives on Chair Design

Due to the industrial development some scholars insist that homo sapiens has become a new race--homo sedens. Since this great degree of behavioral change often cause problems in the spinal column, the appropriate sitting became critical. The nineteenth-century idea of sitting upright position is not considered as a proper sitting any longer. Recent studies by such psychological scientists as A. C. Mandal, Ernest McCormick, and Karl Kroemer show that the spinal column in s-curve with forward bends should be efficiently supported in that manner. Designing a chair sometimes focuses on aesthetic points rather than true ergonomic considerations. Therefore, these result in deleterious effects on human bodies such as lordosis and kyphosis. In fact, it has been overlooked due to the lack of technical and scientific supports. Also, in a mass production, it is hard to meet everyone s need. However, the well adapted ergonomic factors should meet the needs for wide ranges of people. Indeed, in this study we will examine designing chairs in ergonomic perspectives and suggest additional controversial points and altematives.
