Office chair

[4] It was only around 1850 when a group of engineers in the United States began to investigate how chairs could improve health and relaxation by stressing posture and movement.

[5] 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 casters allowed employees to remain sitting and yet reach a number of locations within their work area, eliminating the time and energy expended in standing.

Mid-back chairs offer fuller back support, and with the right ergonomic design, can be sat in for four hours at a time or longer.

High-end chairs in this category, such as the Herman Miller Aeron and the Steelcase Leap are comfortable for long periods.

For appropriately seating above average tall and/or heavy office workers, extra spacious and sturdy constructed chairs are offered.
