The add was misleading. First it was not thick enough for high pile carpet.My chair made dents right away that where hard to get out of after just 1 hour. Second the points on the bottom are not long enough. I have to preposition it at least 3 times a day. This mat at best for low profile carpet.
This said it would be at my home the next day - with free shipping - and it was! That's pretty surprising considering that I live in the extreme boonies... This is perfect to protect the hardwood floors in my home office. It's a nice size too.
