Adequate. Protects area but not easy to roll chair. Mat is too soft & after sitting on roller chair casters form a divot on mat making it difficult for the chair to roll
This product is flimsier than I anticipated. It was already 'indented' with the chair just sitting on it (without me) after just a few hours. That's the problem with on-line purchases; you can't really tell what you're getting until it actually arrives. I needed to get something more solid.
It is a nice chair mat and would have worked well had I paid more attention to the actual measurements. Unfortunately it was a little small for our needs and I had to return it. But I would not have returned it had it fit.
