Adjust So that . . .
Chair 1 Feet are flat on the floor
or footrest, if needed.
2 Legs are vertical forming
a right angle to the floor.
3 Your weight is off your
thighs and are in a
horizontal position. Keep
the back of your knees

do not compress the area
behind them, which could
restrict the blood flow.

and your lower back is
supported with a backrest.
Keyboard 5 Your wrists are straight
and do not flex more
than 15°. They may be
supported but should not
rest on sharp edges.
6 Upper arms are straight
down at your sides, elbows
are close to your sides and
support your arm weight.
Forearms are at a 70° to
90° angle.
Head 7 Your neck is not strained.
Your head should incline
downward, but no more
than 15° to 20°.
