I had similar experience but with much easier solution to my troubles. I've bought bar-stool, in fact i have 2 of them - one actual bar stool and another one more like adjustable bar chair with nice leather finish. So I have 3 options to switch between - staying in front of my standing table, sit on hard stool or better to say lean on it a little bit, sitting on the edge, or sitting on comfy leather chair. This way if I am in a flow I can work however long I need, switchig chairs.
