Chairs
According to NIOSH, a properly designed
and adjusted chair will provide appropriate
support to the back, legs, buttocks and
arms. This support can reduce contact
stress, over exertion and fatigue. It
will also promote proper circulation to
the extremities. Most experts agree that
chairs should have the following features:
- Adjustability
- 5 Pedestal Base
- Seat pan that is not too deep

Most experts agree that armrests are not necessary, unless
they are adjustable.
