I've been using a standing desk for about five years now. I generally use it for 8 hours per day. The only time I don't is when I'm doing a video conference and that's just because I don't have an external camera at the moment. I will say that I preferred my treadmill desk. Standing can be a little tiring. I use a mat and good shoes, but I still feel it in my hips at the end of the day. (I'm about to turn 50). With the treadmill desk, I could feel it in my calves and thighs, but it felt good and was much less tiring. The treadmill was just too heavy to move when we came to Texas, but I hope to have one again. I never had any trouble concentrating on the treadmill. I do find myself sitting to think sometimes from the standing desk, but I think that is the soreness issue in another form.
