So far this mat is doing great. It doesn't slip and my chair rolls smoothly. I do wish the piece that goes under the desk was a little larger since I do roll off the mat on the front end however that is only a very minor gripe. The last mat I had cracked very early on (it was purchased in-store folded down the middle). First it cracked several times down the middle seam then over the next year developed micro-cracks all over. So far this new mat is holding up well without a single crack (about 2 months in)!
We use this to protect the wood floors in our office. It's next to another desk with one from [...] and what a difference! This one is a MUCH better quality- Slides a tiny bit (but not as much as the other)- but looks better (our other already looks worn where the chair wheels are) and all the around is a better value.
I have it under my rolling chair in front of my computer desk so I am able to move so much easier to reach needed items around me on my carpeted area. It is great and just the right size and cleans up so quickly. If I drop anything I still can see what I dropped because it has not discolored .
