Even though my carpet is probably a bit thicker than this mat was made for it performs well...my chair glides well on it and it looks like it will hold up to many years of use.
I bought this to use in my sewing room under my rolling chair. I most likely should have bought the more expensive mat as I am using this on nice carpeting but did not want to spend any more money. This mat works great and does the job I had intended it to do. If I had a choice I would love to have a mat that covers a bigger floor space but am making do with this one just fine. I would buy again if the need arose.
