The chair mat looks great and it is easy to move your chair around on. It is a nice thickness and as far as leaving rolller marks it is not that much. I would definitely buy again. Great quality.
I would have preferred this pad be thicker as I placed it on top of thick carpet. For the moment it seems to be doing fine supporting me and my desk chair.
Poor durability slides around the rug under chair. Needs to be repositioned at least every 2-3 days. Wheels of chair made imprints in it on day one making it difficult to move around. Would not recommend.
