Depth of your chair’s seat
Your chair should be adjusted so you can fit your fist between the front edge of edge of the chair's seat and the back of your
knee.
Height of your chair’s back
This is critical for lower back support. Bypass chairs that have exaggerated supports in the lumbar
region. All you need is a slightly curved back, the height of which you can adjust.
Arm height of your chair
Adjustable height arms help minimize repetitive strain injury (RSI). Set the arm height to put your lower
arms level with your desktop. It should be comfortable to use your keyboard and mouse--you shouldn’t
have to stretch to reach them.
Seat Height Adjustment
Pneumatic height adjustment is nearly a given today’s office chairs. Adjust your chair so that your feet sit
flat on the floor with your upper legs angled downward just a bit. If you’re heavyset, ensure that the lift
cylinder rating is suitable. Inexpensive chairs use lower quality components, among which lesser-rated
cylinders are common.
Adjustable tilt tension of your chair
Inexpensive chairs also often are equipped with fixed-tension settings for the base of the seat. Often this
in supplied in combination with a permanent contact back pad. The result is that the seat and back move
in sync. That can be okay if you’re within the proper weight range for the chair, but for people whose
weight puts them outside that range, it can be difficult to get comfortable in a chair of this type.
On the other hand if you’re very light in weight, moving forward in a chair like this can make you feel like
the chair is trying to eject you. It is also a struggle to lean back since your body weight is not enough to
cause the chair’s back to move easily.
Your best bet is be sure that your chair’s tension is sufficiently adjustable to suit your weight. The bestquality chairs are equipped with automatic tension control, in which the mechanism automatically compensates
for your weight and removes the need for separate tilt tension adjustment. |
