THIS ITEM IS NOT WORTH PURCHASING... TOO FLIMSY TOO THIN CHAIR LEAVES DENTS IN THE MAT EVEN WHEN YOU ARE NOT SITTING IN THE CHAIR... RETURNED THIS ITEM TO THE STORE.
This carpet chair mat is of good quality for the money. It is a lower price point mat so it should be expected to be less substantial than others. It is a little thin and slightly bends over unevenness in the floor surface. Because of this the wheels on the chair will sort of stick between the anchoring cleats of the mat.
