|Testing for the right keyboard height|
Workstation ergonomics are all about creating the least
possible stress on your body by your chair and then your keyboard height
respectively. Below are the steps on how to do this in the right order.
Most people set up their workstation by choosing their desk first
and then their chair. They adjust their chair to fit their desk and have little
concern about the computer keyboard height. This is all mixed up and without a strategy.
Our goal is to have minimal body stress and to be able to
test each additional factor as you add it. To do this you need the chair to be right
first; only then can you set your keyboard to the right height.
Start with a good office chair. (Here is an article about what makes the best ergonomic chairs)
. You need to be able to sit upright
improper seat height causes forward or backward lean of your body. Test this (and
every other step along the way) by sitting there breathing deeply and then
allowing your body to slump as you let it out. If your breathing is restricted
or your body does actually slump forward then adjust your chair height until these
are as good as they can be. These are
actually signs that your body is under extra stress while sitting.
Once your chair ergonomics are correct then you can work on ergonomic
desk height and keyboard placement. Sit at your desk with your hands on your
lap and do the deep breath test. Then
put your hands on the desk top and do the same thing. This is an indicator of
ergonomics in action.

Place a magazine on the desktop and place your hands on it.
Test your breathing again. If it keeps getting better as you add magazines then
go up until it starts to get worse and then go back to the last height where it
was doing good. This is where the desktop should be for you. If you do a
significant amount of keyboard work, then this is the height that the keyboard
should be. If you need to raise the height of a desk then it can be done by placing
appropriate height boards under the legs.
If your breathing never got better than when your hands were
at the height of the desktop then your desk may be too high for you. Place a
combination of books and magazines on your lap and test the same way. If your
ideal desk height is lower than the desktop you would either need to lower the
legs or get a lower desk.
Our Owner’s Manual For The Body has the above breathing
test explained in it as well as all you need to know about improving your
posture while sitting, standing, and sleeping.
