I use this on plush carpet and I have to go along with other reviews... mat does show wheel marks/ruts but it's livable. I'll have to see what it's like in a year as to how it holds up...ie: if it cracks. It's a good mat for the price. ps: A hairdryer helps to get the sticker off.
First one bought lasted about a year (OK). Second one lasted 1 month and cracked returned it and now this one is cracked in two months. Would not recomend this product to anyone.
Have bought several of these the past few years and I would like to see them made more crack-resistant. I am the only person who uses the desk where this mat is used and it is not abused. The wheels of the chair are plastic and yet there are indentation marks on the mat every day.
