What is Ergonomic Chairs
Ergonomics is a popular buzz word today, but it's really all about common sense and
comfort. Ergonomics is the science of improving the human-machine interface and of making sure
that comfort remains a factor in the ways the human body handles modern technology. The
science is used in everything from the design of executive ergonomic chairs to the design of
the position of the buttons on ATM machines. The idea is to design equipment and systems that
enhance human comfort while operating modern technology so that the human is comfortable
enough to be as efficient as possible while working and using the systems. We often hear
about ergonomics as it relates to computer usage; bad ergonomics is what causes repetitive
motion injuries such as carpal tunnel systems. Many ergonomic devices have been designed with
more comfortable computer use in mind, from ergonomic computer chairs and ergonomic desk
chairs to wrist rests and keyboard trays. Positioning of the computer monitor at the proper
height and difference is also another important ergonomic issue. Ergonomic office chairs
should basically avoid any physical problems that an uncomfortable chair could cause.
Ergonomic desk chairs should be at the proper height to position your body in relationship to
your work surfaces, or be adjustable so that you can set them at the optimum height. Ergonomic
chairs should have the proper depth of seat so that your legs bend normally and circulation
isn't impeded by the edge of the seat. Many ergonomic desk chairs will accommodate a slight
rocking back-and-forward motion, which can help improve circulation by exercising the leg.
Other ergonomic desk chairs utilize a balance ball to force your body into a neutral position
that insures proper spinal alignment. The term "ergonomics" comes from the Greek words for
"work" and "natural laws." Essentially ergonomics applies science to the analysis of how
humans work most comfortably and efficiency. People who practice ergonomics study how people
work, what their positions are, what their motions are, what interferes with their working
comfort and what enhances it. They then draw upon those findings to design ergonomic products
such as office chairs that let people work comfortably for longer periods of time, and avoid
injury. If you feel tired or achy after a day's work, it's wise to observe your own
ergonomics. Does your chair position you properly to look at the computer monitor without
tilting your head? Does it position you comfortably to reach the keyboard or the desk surface?
Do your legs reach the floor without being bent too uncomfortably? If the seat height seems
right in relationship to the floor and the length of your legs, then you may need to raise or
lower your monitor and your keyboard shelf to find the overall position that lets you work
without discomfort. |
