I was a little confused by description online and what I actually got. The description says low pile carpet mat but the product was actually labeled berber carpet mat. However I have shoved it under the edge of my desk where it can't move so working okay with my low pile carpet. However my biggest disappointment is that it is already getting dents from chair wheels. I was hoping with this expensive of a product it would be sturdy. I am not overweight 140 pounds and I only sit here a few hours a week. Again disappointing I try to move wheels around to prevent this but only so many places 5 wheels can go on a carpet chair pad.
The material is very thick and substantial. If you have deep carpet and or a heavy chair this is a good solution. The plastic material is clear and vey flexible hopefully it remains this way over the long haul.
