For the price and that I’m not going to be using it every day permanently it’ll do. But do believe the reviews that it dimples immediately. And so far the dimples don’t go away overnight after you move your chair off of it. Wish I’d have believed the reviews and spent more for a good mat.
Purchased this last month and placed on top of what I consider 'normal' residential carpet (non-berber carpet). This chair mat is not thick enough plastic to support my office chair. After just a few minutes of sitting the chair's wheels create 'divots' in the plastic mat and after a few hours creates a memory of where my chair was. Spend the extra $ and get a thicker mat if you are going to place on top of non-berber (low profile) carpet.
