I've got my monitors on 2 boxes adding about 6 inches each to their height. When I first started looking up to use them it was so uncomfortable and distracting that I could not work. I kept at it though and I find my posture has improved and the thought of going back is now uncomfortable. I also recommend the following exercises which have improved my posture such that people have been saying that I look taller. https://www.youtube.com/watch?v=FTV6UCh-yhs https://www.youtube.com/watch?v=FTV6UCh-yhs I have been doing them against my wall when I have 5 minutes to wait for a build or in the shower when I'm rinsing off.
