The neutral posture is the ergonomic standard for sitting in a chair and using the computer or standing. The ideal positions support the natural curves of the spine and maintain your body in good alignment. The characteristics of the posture are described below.
|Head is centered and positioned directly above the shoulders and hips.
|Back is straight up and down (vertical), and not leaning forward or back at the waist.
Upper back and lower lumbar curve are supported by the chair’s back or backrest.
|Neck is relaxed. Chin is at a comfortable level without excessively lifting the chin to view the monitor.
|Shoulders are relaxed and are not lifted upward towards the neck.
|Upper arms are relaxed and rest close beside the upper body.
|Elbows are relaxed beside upper body and are bent at a right angle, 90° to 110°. Elbows are not lifted upward and/or outward away from upper body.
|Forearms are not extended since upper arms are relaxed beside the upper body.
|Wrists are relaxed and straight/flat, or flexed slightly downward.
|When sitting in the chair, knees are at the same height or slightly lower than the hips.
|While sitting,feet should rest comfortably on the floor, or are supported by a footrest if the feet do not touch the floor. If you are standing, keep your knees unlocked and consider using an anti-fatigue mat with beveled edges that sits flat on the floor.
