Abstract

Office goers have been compelled to or increasingly constrained to remain seated in a chair–desk complex. Assessment of seat dynamics and user-seat compatibility has been examined, using approaches such as anthropometric, biomechanical, electromyographic and stabilometric analysis, comfort rating and materials construction. This chapter describes biomechanics of sitting, analysis of sitting modes and seated features, and aspects of Balans chairs. Further, it elaborates the ergo-design characteristics of an office chair, including different chair tilting mechanisms. Methodological details of the simulated seat–desk system are included for human–seat–desk interface analysis, covering the effects of the slope of the seat pan, backrest angles, height of armrest, upright and slouch sitting, about body force distribution and muscle activation. Several general risk factors, such as seating system, repetitive use of keyboards/mouse, chair–desk with or without adjustable armrests, supported/unsupported forearm and wrist, are all interconnected and compelling components of workplace constraints in computer work. Discussion includes options of good job design, periodic task rotation, rest breaks, stretching exercises in relieving the physical and mental strain of computer operators.
