While this chair mat does provide coverage to prevent carpet wear my chair wheels create impressions in the mat and it makes it difficult to roll around easily. I'm not that overweight and it seems this mat should either be thicker or more durable so the wheels of my chair don't get stuck.
I have executive Chair and the size of this mat is perfect for chair and mat does not ruin the carpet(well that's what it is for). Very much happy about the product
Too flimsy; already getting wheels making indents in the mat. Nothing in material about the the mat indicated that a 50 lb chair (purchased from Staples) sat in by an average adult would create dents in the mat.
