Some benefits of using a well-designed and appropriately adjusted ergonomic office chair while using a computer include well-supported back, legs, buttocks and arms; a reduction in awkward postures; less contact stress; and minimized forceful exertions, explains the Occupational Safety & Health Administration. Ergonomic chairs support the worker's body in a neutral position, which reduces the risk of developing a musculoskeletal disorder.
Sitting in positions that are not neutral increases the stress and strain on muscles, tendons and the skeletal system, claims the Occupational Safety & Health Administration. This strain contributes to musculoskeletal injuries. Additional stress on the body also causes people to feel fatigue, swelling, numbness and pain.
Ergonomic chairs benefit the employer, claims Ergonomics Inc. Employees who use ergonomic chairs at work are less likely to be injured and thus less likely to have lost productivity due to leaves of absence. Also, fewer injuries means less worker's compensation insurance costs for the employer.
Ergonomic chairs for use at a computer workstation should move easily along the floor, notes the Occupational Safety & Health Administration. The backrest should curve with the spine and adequately support the lumbar area. The chair's seat height should be adjustable so that the sitter's feet rest flat on the floor.
