I need to install a ring of anti-fatigue mat material (foam/rubber) that has an outside diameter of 20 ft and inside diameter of 12 ft. I seem to only find it sold as interlocking squares though (such as what is used in gyms or children's play areas). I'm contemplating buying enough foam squares and cutting them to shape but I wanted to know if there was a better solution.
Is it possible to purchase either circular versions of this flooring, giant sheets of it, or angled tiles (for a polygon)?
