Although I do not have a "high pile" carpet I purchased this chair mat because I weigh well over 200 lbs and sit at my desk in front of my computer for a minimum of six hours a day. This is the type of "heavy duty" chair mat needed by someone like myself and I would recommend it to anyone weighing a minimum of 200 lbs.
I LOVE THE MAT BUT THE LABEL THEY STICK ON IT TOOK ME 30 MINUTES TO TRY GETTING OFF. I PURCHASED TWO MATS SO THAT WAS AN HOUR OF MY TIME. OTHER THAN THAT IT IS GREAT - WHY THEY PUT GLUED LABELS ON SOMETHING LIKE THAT I WILL NEVER KNOW.
This carpet states that it is for up to 3/4 in. plush It moves all over the place it is possible that the company sent me the wrong one but had the right tag on it. Called but no other in stock.
This is a great regular use office chair mat. It was the most inexpensive one that I could find and since I hate spending money on stuff like this it was a good buy. I have only had it for a few weeks but it appears that it will hold up just fine. I did have a bit of a problem with shipping of the items. I ordered 3 and received only 2 of them and one of the 2 had the corner all splintered and cracked. I called to see what had happened to the 3rd one and what to do with the cracked one and they immediately made arrangements to replace the cracked one and get the 3rd one here the next day. I am sure that the -30 degree temps we were having at the time was the reason for the damaged one. Regardless they remedied the situation by the next day.
