How do I adjust my office chair for maximum comfort?

The office chair was strategically designed to increase the productivity of clerical employees by making it possible for them to remain sitting at their desks for long periods of time. A swiveling chair with caster wheels allowed employees to remain sitting and yet reach a number of locations within their work area, eliminating the time and energy expended in standing. The wooden saddle seat was designed to fit and support the body of a sitting employee, and the slatted back and armrests provided additional support to increase the employee’s comfort. Like our modern chairs, many of these models were somewhat adjustable to provide the maximum comfort and thus the maximum working time.
