If I could find the receipt I would return this. Very thin and after a couple weeks of use the wheels on my office chair are already getting stuck in the grooves.
It's a good chair mat especially for the price but the description is not accurate. The pile nubs on the bottom are NOT 3/8" long they are 1/8" at best. I don't think this is going to hold up well on my carpet in the long run. But the larger pile mats are so much more expensive that I'll just keep this and hope it lasts until I'm no longer working from home.
The mat is a little bit soft for my taste. It's supposed to be designed for carpet but the wheels leave indentations in the mat which makes it a little bit hard to slide around. I would get something stiffer next time.
