Ergonomics is the study of designing and arranging objects and environments to fit the needs and capabilities of the people who use them. In the case of an office chair, it should be adjustable, provide proper support to the back and neck, and promote good posture to prevent musculoskeletal problems.

The best position for a computer monitor is one where you can clearly read the text without any discomfort or strain on your body. Leaning forward, twisting your neck, or looking too far upwards can lead to neck and back pain, as well as eye strain. Seeing overhead lights reflected on the screen can cause glare and make it difficult to read the text. Therefore, the best option is to position the monitor in a way that allows for comfortable reading without any strain or discomfort.Rate this question:
