Ergonomic seating
Ergonomic seating can be defined as a comfortable working posture with a natural alignment of all your joints from head to toes. Before discussing on how to set your computer workstation, let’s have a look at the concept of Ergonomic seating (neutral body positioning).
This method of Ergonomic Seating helps you reduce the stress and strain on the muscles, tendons, and skeletal system thus reducing the risks of developing Ergonomic problems.

- Ensure that your hands, wrists, and forearms are in a row, straight, and almost parallel to the floor.
- Ensure that your head and torso are in-line with head slightly bent forward, facing towards the front, and balanced.
- Ensure that your shoulders are at ease with upper arms hanging normally at the sides of your body.
- Ensure that your elbows are close to your body and bent between 90 and 110 degrees.

The feet should be either supported by a footrest or should be relaxing on the floor.
- While leaning back or sitting in a vertical position, ensure that your back is supported fully with firm hold on the lumbosacral area.
