After a week with using the mat I am content with its results; my stool glides across the surface and it's protecting the carpet. Although I miscalculated the length of the carpet to be short enough the mat still stayed in place. The only minor downside is the indenting in the mat but that's kind of expected because of that said carpet length miscalculation.
The mat served our purposes for the most part of having a mat for rolling my chair on top of my carpet. But the mat is a little on the thin side and so the wheels are already making dips in it. I sort of wish that I'd bought something sturdier.
