I use this for my home office. It serves the purpose adequetly I guess. But the plastic deteriorates withing a year. With low pile carpeting it's going to do that. They have one for more money. I figured just buy a new one every year. Nothing last forever.
When I first saw the mat the quality and heavy thickness seemed perfect to use on my plush 1" pile carpet. But after one use I discovered that the mat is not sturdy enough to prevent my office chair wheels from sinking into the mat when I'm sitting down. This renders my chair completely stuck in plastic sink holes so my chair will not roll on its wheels. Bummer. In general however I would say that the mat would be a very nice quality mat for low to medium pile carpets but not high pile.
The description on-line lead me to believe this was a heavy duty mat for use on a thick carpet but it is no better at resisting divots from the wheels of a rolling chair than my old flimsier mat. [...]
