In the latter part of high school, I began standing in the classes where I both knew the teacher fairly well and didn't think I would bother anyone else by doing so. Since there weren't any standing desks, I would either stand myself near a wall or an unused desk I could lean on and carry a clipboard, or I would occasionally grab a music stand or an unused lectern. I had never felt particularly uncomfortable in a normal desk before, but for the first time I really felt unconstrained by my environment. I'm naturally somewhat fidgety, and gaining the ability to readjust my body comfortably without bothering anyone and to pace around the classroom (even in a very small area) really allowed me to get my blood flowing more easily and prevented me from being distracted from any discomfort I had in a desk built for people who were both smaller than I was at the time and who were not left-handed. Talking to the teacher (or even to other students) feels much more intimate, as your vision isn't obstructed by the back of someone's head. Something I didn't expect was that when participating in class discussions, I felt more expressive, as I tend to move my hands and arms when I speak, something I couldn't do easily in a sitting desk.<p>I wonder, though, whether or not some of both the student's and my improvements were caused by being on a different plane from the rest of the class. I also wonder what effect having some standing students in a classroom would have on the seated children. I was once told that I was somewhat intimidating when I was the only one standing in the classroom.<p>I don't know whether standing desks are the best option for everyone, but they're certainly a better option for some, and I'm glad to see standing desks being given greater consideration nowadays.
