This chair mat is smaller than most and that is what I needed for my home office. I am using it on medium pile carpet so it does tend to creep some. Over all the price was right for home use. Other office supply sources did not have one this size.
The mat is a good size and protects the carpet; however the plastic used is quite thin and I still create little divots with the chair castors. Also its expensive for the thinness of the plastic.
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.
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.
