T
Your seat depth should allow your lower back to
comfortably contact the backrest. Make sure that the
backs of your lower legs do not press against the front of
the chair.
T
Extend your lower legs slightly so that the angle between
your thighs and lower legs is 90° or more.
T
Place your feet flat on the floor. Only use a footrest
when attempts to adjust your chair and workstation fail
to keep your feet flat.
T
Be sure that you have adequate clearance between the
top of your thighs and the underside of your workstation.
T
Use armrests or forearm supports to support your
forearms. If adjustable, the armrests or forearm supports
should initially be lowered while all the other
adjustments discussed in this appendix are made. Once
all these adjustments are completed, raise the armrests or
adjust the forearm supports until they touch the forearms
and allow the shoulder muscles to relax.
