Inexpensive but not cheap. It does what it is supposed to do and looks great. It does tend to have dents from the chair legs but not terrible and so much better than carpet alone.
Old mat failed after many years and I saw Staples was open (a necessary store). I purchased mat and put it in place; chair rolls nicely. Mat is good size and does its job.
I thought carpet chair mats were the same but because it's hard for me to roll on I probably should have ordered an harder mat. I guess it depends on the thickness of the carpet.
