What is ergonomics? Ergonomics is the science of fitting the job to the worker. When there is a mismatch between the physical requirements of the job and the physical capacity of the worker, work-related musculoskeletal disorders (WMSDs) can result. Workers who must repeat the same motion throughout their workday, work in an awkward position use a great deal of force to perform, repeatedly lift heavy objects or face a combination of these risk factors are most likely to develop WMSDs.

Most ergonomic chairs have a seat with a front that prevents the seat from catching you behind the knees. The seat should also be contoured to allow even weight distribution and it should be comfortable to sit on. Is the seat chair height adjustable?
