As other reviews have noted it is thinner than some mats which makes it a little harder for the chair wheels to move. Our carpet is low pile so not a big issue. We have only been using this for a few days so time will tell how durable it is.
I bought 2 of these for my home office and they are very nice. Our carpet is pretty thick and these mats are heavy enough to keep the chairs from sinking down into it. I'd definitely buy again.
