This is a great carpet chair mat; however it required spending a LOT of time soaking and scraping the label on it in order to remove it from the top surface...it would not peel off but needed to be soaked several times with much scraping inbetween each soaking.
The mat itself is nice and the 'teeth' underneath keep it in place on the carpet. This is probably a function of the wheels themselves sinking into the mat + carpet; there are some indentations in the mat from where the chair is stationary/when I'm sitting in it. Not sure if that can really be avoided though.
