HP OmniBook XE Setup Manual page 35

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.
A freely rotating swivel so you can move easily from side-to-side.
Fully adjustable and padded armrests. The chair arms should not interfere with
adjusting the chair or moving it close to your work surface.
Your Work Surface
Ideally, you should be able to adjust the height of your work surface.
A simple way to ensure your work surface is at the correct height is to first adjust the
height of the seat-pan of your chair. With your chair properly adjusted and your feet
firmly on the floor, adjust the work surface height until your forearms are parallel to
the floor when you have your fingers on the keyboard or other input device.
