Adjust So . . .
Chair Feet are flat on the floor.
Legs are vertical forming a right angle to the floor.
Your weight is off your thighs and they are horizontal.
Keep the back of your knees away from the seat so
you do not compress the area behind them, which
could restrict the blood flow.
Your upper body is erect and your lower back is
supported with a backrest.
Keyboard or mouse Your wrists are straight and do not bend more than 15
degrees. They may be supported when resting but not
on sharp edges. Type comfortably, with no more key
pressure than needed to feel the contact point.
Upper arms are straight down at your sides, elbows are
close to your sides and support your arm weight.
Forearms are at a 70 degree to 90 degree angle.
If you use a mouse, rest your hand on the mouse so
your wrist is not on the work surface. Operate the
mouse close to your body’s centerline.
