I have been using my standing desk for about a month now. I thought in fact I would hate it and give up soon but it turns out I don’t mind it at all. Most of the time I forget I am standing being focused on my work. And when I get tired I use my wood/chair/thingy for few minutes to relax my muscles. I am always barefoot though and I definitely need a mat for a bit of cushion. Otherwise I am good with it!
