This is a nice chair mat for the price. It works just fine but I will say it is a bit thinner than other mats I've had. It has developed slight dents/grooves where the chair wheels sit so I have to give a push sometimes to get my chair to roll free. I have this mat over an area rug so maybe this wouldn't be an issue if you are using the mat on solid flooring rather than carpet. Overall I would recommend and buy again for the price.
After the first time I sat in the chair in front of my computer the chair left notches in the surface of the chair mat. I guess I should have gotten a mat with a harder surface.
This chair mat fits my needs and is just the right size. Part of it goes under the desk where my legs and feet are and the rest of the mat is secured to the carpet by small plastic rivets to keep it from moving. Great product.
