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.
This is a temporary solution until the virus crisis subsides. It will be ok on low pile carpet so the office style chair wheels do not wear holes in a carpet or rug. It is more affordable and available than the competitors but I can tell it will not last long. The wheels do make little dents after 20 minutes. Not for a big person or heavy chair.
