The carpet chair mat was a perfect fit for the small area I needed it for setting up a work area and carpet didn't allow me to roll the as easily but with the mat its no problem and affordable
I bought this mat to replace one intended for uncarpeted floor which kept sliding sideways. I currently have low pile carpet where my desk is. I thought this one would solve my problems but it created a new problem (in addition to inching to the right) - - the chair wheels form sink pockets in the mat wherever they sit (and I am a small slim person) and I fight the dents when I try to shift the position of the chair. I could not recommend this mat to anyone with a low pile carpet. Maybe it works well on other some kind of floor cover but I'm not sure what that would be.
Not a bad floor mat; a little thinner than I expected so the wheels of my chair create indentations in the plastic of the mat causing four little indentions where you have to make a concerted effort to move it out of them---it's now harder to roll the chair.
