The implementation of the five point base in office chairs was a major development, as this simple construction change almost completely eliminates the tendency of office chairs to topple with the user still seated. Another innovation in modern chairs for the office is the use of gas height adjustments that double as a shock absorber upon taking a seat. It is amazing how so many little changes work cumulatively to create a chair that is far more durable and functional. By functional we refer to the chair’s ability to be used for longer stretches of time with lessened operator fatigue.
