What can be done to improve sitting posture at a desk?

Adjusting chair height and desk setup is crucial for improving sitting posture at a desk. Proper ergonomics ensure that the body is in a neutral position, minimizing strain on muscles and joints. For instance, the chair height should allow the feet to rest flat on the floor and the knees to be at or slightly below hip level. The desk setup should accommodate the natural position of the arms, allowing for relaxed shoulders and elbows at about a 90-degree angle. Additionally, having the monitor at eye level helps reduce neck and back strain, further promoting a healthy posture.

The other choices do not adequately support the need for proper posture. An oversized chair can lead to poor positioning and lack of support. Sitting in a relaxed position may sound comfortable, but it can lead to slouching or other poor posture habits. Relying solely on a standing desk does not guarantee better posture; it requires proper adjustment and use to be effective.
