> For me one of the big motivators was that my chair was pushing my shoulders forward. It wasn't the typing causing forward rounded shoulders, my chair's concave back rest actually put me into that position. I probably could have fixed it with a pillow or a better chair, but I also wanted to stand.
In case anyone is curious about the pillow route, I bought an upside-down T-shaped pillow like this one for my cheap/generic office chair. It forces my shoulders back when sitting in a slightly reclined position and keeps my back straight. Overall it's helped quite a bit with my posture and back pain.
