Here at our work we purchased anti-fatigue mats for certain areas in our shop for people to walk and especially stand on. They told me almost instantly how much they loved it and how it saved their legs and backs from pain. I have no doubt they work. Doug, what if a fella just placed one of these on top of his carpet as a throw down as they can be ordered or cut to fit in any size? Not a bad idea but I'm not sure that there would be a sizeable market for it though.
