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.
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.
Just received this product a few days ago. i like that it does not slip on my carpet. However there are indents where the chair has landed. This make it difficult to move the chair around. I don't recommend it.
