This is a little thin to be used on thick home carpeting with padding. I should have purchased one of the thicker more expensive alternatives however it does work OK.
This mat helps so much with my desk being in a room with longer pile carpeting will get another for my sons room when it comes time for him to use the desk under his bed!
MY husband decided he wanted a chair mat because I have been using one for a number of years and his chair is on a rug and just thought it would be easier for him to maneuver around. He loves it as I do too although mine is on a floor.
