Comfortable, adjustable, ergonomically designed furniture
er·go·nom·ics
“an applied science concerned with designing and
arranging things people use so that the people
and things interact most efficiently and safely -called also human engineering”

Things to consider:
Desk
Computer
Keyboard trays and
mechanisms
Document holders
WORKSTATION
“Ergonomic work station
set-up: alignment of
keyboard, document and
monitor precludes
dangerous twisting and
minimizes the risk of
associated injuries.”

At the keyboard, wrists
should be elevated, hands
should not be up at a
positive angle carpel
tunnel
Keyboard with tray should
be pulled in so your bicep
and forearm are
perpendicular, no reaching as
this will cause strain on
shoulders
Ergo Articulating Arm
Rests
•For the
prevention of
carpal tunnel
syndrome are
achieved when the
bottom of the
Ergo-rest arm
pads are
positioned level
with the lowest
keys of the
keyboard.
Clear mouse bridge- for
bringing your mouse closer,
avoid reaching, prevent
shoulder and arm strain
 Wrist rests for keyboard and
mouse- elevate wrists so they
are at a negative angle
-prevention of carpel tunnel

Movement
Musculoskeletal
Disorder

“musculoskeletal disorders
(MSDs) ...constitute the
largest job-related illness and
injury problem in the U.S.
today.

Contact stress affects the
soft tissue on the fingers,
palms, forearms, thighs,
shins and feet. This contact
may inhibit blood flow,
tendon and muscle
movement and nerve
function."
Proper Sitting Position
A negative slope keyboard in a
lowered position keeps wrists
straight (neutral posture), opens
up elbow angles and hip angles,
keeps shoulders neutral and
encourages recline, which reduces
stress on the spine.
Workplace Problems and
Solutions
Problems
1. Neck tension, tightness, upper back
and shoulder discomfort
-Hands and arms not supported while
typing
2. Hand, wrist and lower arm
discomfort. The wrist is deviated
in an unnatural position.
3. Lower back pain discomfort
-Lumbar curvature is not being
maintained and supported.
4. Thigh discomfort.
-Too much pressure on the thigh
because chair is too high and legs
are dangling.
Solutions
1.For typing tasks, adjust the armrests
to the correct height and angle to
support the weight of the arms and
use palm rest or wrist rest.
2.Set the keyboard and/or
calculator to produce a neutral wrist
position.
3. Bring backrest closer by tilting
forward, and adjust height of
lumbar curvature of backrest. It
should be slightly above the pelvis
to provide support in the lumbar
region (lower back).
4. Lower chair height so that feet
are supporting feet and lower legs
only.
Adjustability
Seat Height Adjustability
feet to be flat on the ground to avoid stress on
your hips and lower back
Arm Height
Keep forearm at right angles to your shoulders
This will keep your shoulders and neck
muscles relaxed
Arm Width
Increase distance between seat cushion and
arm. For optimum comfort and support, your
arms should rest at shoulder width
Adjustability
Con’t
The height of the back can be
individually adjusted for lumbar
support.
The independent back angle adjustment
allows the users to adjust backrest angle
while seated and than release to lock on
desired position.
By sliding the seat cushion forward or
backward; the support for the legs can be
individually adjusted.

Knee tilt


Knee tilt mechanism: this gives a chair the
ability to free float smoothly within a wide
range
The fulcrum for the rocking mechanism is near
the knees to allow for further forward motion
Multi-tilt
Multi-tilt mechanism: fulcrum in the middle creates
less range
-there is an extra lever to angle the seat pan further

“This natural, stress free
position is the body s
preferred posture, similar to
the free floating posture
experienced when you
totally relax in a swimming
pool, or the posture typically
associated with astronauts
floating in space.”
