Postural And Physiological Criteria For Seating: A Review

摘要

For centuries chair sitting has been a major posture forwestern people. They adopt this body position during mostof their daily occupations, let them be working or leisuretime activities. Changing patterns of workfincreasing paperwork), development of industrial technologies(automation,remote controls) and changes in the modes of recreation (TV)increase the time during which people sit. Parallel to theincrease of the sitting workers and to the increase of theinterest in the factors influencing worker efficiency, therestarted the studies on the ergonomics of sitting and seating.Since late 1940s there have been many attempts to formulizethe optimal requirements for seats. These requirements wereusually based on the concept of the physiologic comfort ofthe user. The aim of this paper is to review some of thesepast studies and thus to present a collective argument thatleads to the physiologic criteria for seating design
