A sturdy monitor stand can have a number of benefits for both your posture and your overall ergonomics. Here are a few key advantages:

1. Improved posture: A monitor that is at the correct height can help you maintain a more natural posture, which can reduce the strain on your neck, shoulders, and back. Having the monitor at eye level can prevent you from hunching over and can help you sit up straight.

2. Reduced eye strain: A monitor stand can also help you position your monitor at the correct distance from your eyes. This can help prevent eye strain and fatigue, which can be caused by having your monitor too close or too far away.

3. Increased desk space: A monitor stand can help you lift your monitor off your desk, which can free up valuable desk space. This can be especially helpful if you have limited desk space or if you need room to spread out documents or other work materials.

4. Increased airflow: A monitor stand can also increase the airflow around your monitor, which can help to keep it cool and reduce the risk of overheating. This can help to prolong the life of your monitor and can help prevent crashes caused by overheating.

5. Design and Aesthetics: A monitor stand can also improve the look of your desk setup as well as giving a more professional look.

Overall, a sturdy monitor stand can have a number of benefits that can improve your posture, reduce eye strain, free up desk space, and increase the airflow around your monitor. If you're looking to improve your ergonomics and make your work setup more comfortable, a monitor stand is definitely worth considering.
