This mat is about 1/2 as thick as one I purchased from Staples about 10 years ago. That one was "High Pile" as well. I'm hoping the new one will provide similar service. We'll see!
Does what it says it would. I have a high-pile carpet and we already had to take everything out once because the carpet moved. Now I bought the chairmat and tucked it under the desk to make sure that the carpet doesn't move when the chair moves back and forth the carpet stays in place. Like I said it does the job it is supposed to do.
