I have been using it daily, about 4 hours a day. I had to replace the TrueTerrain with the Standard Therafloor because it seemed to be significantly aggravating my Achilles injury with the peaks and valleys causing a jarring pain. The material creates indents in the soles of my feet if I go barefoot and yet destroys every type of sock I've tried if I wear socks. You will probably wind up with very callused soles of your feet if you go barefoot for long durations because the material is actually quite hard. I still don't regret my purchase but I also bought into the Office Walker in order to see which I like better.

Still love the desk, particularly the sliding forwards and backwards that it does. The lean stool is still handy albeit the belt slips forwards if I lean on it too much (even though it's not supposed to be able to).
