Choosing Your Keyboard mechs and trays
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
•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.

“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."
Musculoskeletal Disorder
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.
Proper Sitting Position
Problems1. 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.
Workplace Problems and Solutions
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.
Seat Height Adjustabilityfeet to be flat on the ground to avoid stress on your hips and lower back
Arm HeightKeep forearm at right angles to your shouldersThis will keep your shoulders and neck muscles relaxed Arm WidthIncrease distance between seat cushion and arm. For optimum comfort and support, your arms should rest at shoulder width
Adjustability
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.

Adjustability in the Chair
Multi-tilt vs 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 mechanism: fulcrum in the middle creates less range
-there is an extra lever to angle the seat pan further
