Your Chair
It's very important that your chair provides a comfortable sitting position and offers the
following features:
• A stable base, such as five legs with casters. Make sure the
casters are designed for the type of floor you have in your workspace, whether it is
bare or carpeted.
• A height- and tilt-adjustment feature. It should be easy to adjust
your chair height from 40 cm to 52 cm (15.5 inches to 20.5 inches) as measured from
the top of the seat pan to the floor. If you are much taller or shorter than average, you
may need a chair that can be adjusted beyond this range. Adjust your chair so that the
work surface or keyboard tray is at elbow height and your feet are flat on the floor
with your knees slightly bent below your hips. Ideally, the seat pan should be able to
tilt both forward (minimum of 5 degrees) and backward (minimum of 10 degrees). If
the chair has an adjustable seat pan, inclining the seat slightly forward will transfer
some of the pressure from the spine to the thighs and feet. This will relieve pressure
on your back.
• A curved seat edge. The front of the seat should be curved and finished in a
"waterfall" edge.
• An adjustable back support in both height and forward and backward tilt.
It is important that the backrest correctly supports the lower part, or lumbar curve, of
the back.
