The product was fine, however, I mistakenly thought it would prevent my office chair rollers from running out from under me whenever I tried to sit down after we put down a wood floor in living room where my office corner is located; Ironically, the chair seems to go faster with the mat than before. I realize the mat was better suited for making a chair move efficiently with a RUG in office area or so it seems. I will put down a throw rug and the mat on top and see if that solves the runaway chair problem. It is unlikely the mat's fault, just a fluke for my chair.
