I have old carpet throughout the entire house which I will be replacing with hardwood soon. But for now I needed to be able to roll my desk chair up to my desk in my little office. This mat was inexpensive and works well for my need.
Although this says medium pile carpet it moves across the carpet as I stand walk or sit in my chair on it. I had to put my desk on it to keep it from moving. The chair casters do push in a bit but it does recover. I think it should be rated for low pile carpet. My carpet is a cut and loop lower pile with a good firm pad. I guess it's not that low of a pile.
Arrived at scheduled day. Good sturdy plastic mat. I recommend this mat. Check the carpet-mat thickness table before ordering. The table is very useful as it guides which mat type to purchase.
