I recently refinished my hardwood floors and though the Waufair description said I wouldn't need to order an anti-slip rug mat for under it, I had my doubts. I have actually fallen in sock feet on the new floor finish and I have seen my cat take a spill just coming around the corner in the hallway at a medium pace.  I am very happy to report, however, that this rug is just as advertised.  It doesn't need the anti-skid mat.  It is great exactly as it comes. I love the colors, too.
