+200 lb guy siting on a wheeled chair makes the wheels sink in a little bit and hard to start moving but once I am going it rolls fine. I think if it were a little thicker it would help stand up. Also was very dirty when I got it delivered. I had to clean it 2-3 times before the papertowel came back clean. Forget trying to clean the bottom spikes make that impossible. Maybe with a hose outside but its winter now... dirt was mostly dust and grit. Looked like someone had dragged it through a dessert before puting it on the truck. icecream and chocolate sauce everywhere.
Chair mats get brittle over time. This one was purchased to replace an old mat on a medium plush office carpet. While not quite as large as I expected although I did measure it does fit the area and is pliable making it a good purchase for the "over the carpet" application. I also hope this one does not become opaque over time...looks great now. Not sure what else to say about a low pile carpet chair mat. I did have it shipped to the house and delivery was prompt with minimal packaging and it arrived undamaged!
