Not as thick as I thought it would be. My chair creates temporary pockets that then make it hard to move the chair - seems as if the chair is stuck in n a valley. Seems to be durable and it ahears well to the carpet .
This is my second purchase of this product. The first lasted between two and three years. This mat seems better than the prior mat. I believe that this one is heavier i.e. it is a thicker mat. It's too soon for me to say how it will last. As mentioned I believe that the prior mat was a little-bit lighter than this one. So I'm expecting this one to last longer. Even if it only lasts two year I believe that it's a good value. I replaced the old mat because it had developed some cracks. After two year that's probably okay. I use the mat in a home-office environment. I have a chair that sits on the mat. I sit in the chair for all the work I do on my computer. The mat sits on a wall-to-wall carpet that is in the room use for an office. The prior carpet protector did a commendable job of protecting my carpet. The current one (the one being reviewed) appears to have the same potential.
We have a low pile carpet but the mat is definitely to thin for low pile as my office chair sinks into it. There needs to be a better definition of this on your website. I'm very frustrated right now and I'm going to return this for a much thicker mat.
