You spend a lot of time in your office chair every day.
More often than not, more time is spent in this chair than
in your living room easy chair, which you carefully selected
for personal comfort. The same attention toward the comfort
in your daily office chair should also be considered. Some
pointers for finding the appropriate office chair for you
follow.
Some overall general principles to keep in mind with regard
to office chairs are:
1. You need proper back support and ideally your back
should be at an angle between 90 and 105 degrees.
2. Your feet should comfortably reach the floor.
3. Your thighs should be parallel with the floor and
well-supported.
4. Tilting back should be easy but not so easy that you
can tip over.
The most important feature in an office chair should be the
back support. When the backrest is contoured to conform to
your body's natural shape and your size, you are supported
the right way. Many back supports adjust to various heights
and are adjustable at any time.
A soft seat is not the most conducive for proper posture
throughout the workday. While a soft lounging chair is fine
while kicking back in front of the television, a stronger
supporting chair is needed to prevent muscle fatigue. The
most ideal office chair cushion is sculpted flat so that
your thighs and bottom as best supported. A slight slope
forward will also improve your leg's circulation throughout
the day.
Another important feature of a good office chair is the
ability to easily adjust the chair during the day to match
the changing needs of your body. The controls should be
within a comfortable reach of the seated occupant and the
controls should smoothly adjust the positioning of the
chair. This type of control is especially important for
people who sit at a computer screen for a large part of
the day.
A good office chair has casters that allow for easy
movement across the floor or carpet. The newer office
chairs feature five casters in comparison to four casters
on older office chairs. Office chairs with five radial
legs are safer and more stable than the older chairs with
only four legs.
Sitting most of the day takes a toll on anyone's back.
Taking care of your back requires not only finding the right
office chair but also taking a break from sitting at least
every half hour for about two minutes. If this type of
stretching is not an option, try shifting positions
frequently to maintain a strong posture. Another related
influence on positioning in an office chair is making sure
you have a correct glass prescription, especially if you
work on a computer screen. The wrong prescription or
glasses cause improper adjustments on how you tilt your head
while seated and how you move to read the screen clearer.
