Ergonomics is a science between the design of your body and that of the object you use repeatedly. It is also known as human factor engineering. It matters to you as long as you are using something over a period of time. Basically, the better the fit between you and the object is, the less injury-prone you are and the better your productivity. As we spend more time in front of our monitors every day, the importance of office ergonomics also grows. Ergonomic office chairs and desks are easily what we interact with the most during a normal workday.
