Haven't had mat long enough to really review it but have noticed my chair wheels make impressions on it. Not as thick and heavy as my last mat. It looks nice.
Mat is way too soft Castors leave big indents. Not happy with it. Unfortunately I had to cut a notch in it to fit around desk leg so I can not return it or I would
The chair mat that I purchased was one that should work well with high pile carpets. It crawls and bunches up when it crawls up against some thing such as a desk. I wish I had'nt bought it. Not happy with the purchase. It needs to be twice as thick to be stable enough.
