I had a carpeted area in front of my desk and I was ruining the rug by rolling over the edge of the persian rug. The mat immediately solved the problem. The area under my desk is wood and the mat had no problem transitioning from the rug to the wood. It looks and feels robust and I am confident that I will get several years of use out of the mat. Your catalog should give the thickness of the mat and the lengths of the pegs that grip the rug (I would estimate the grip peg lengths as 1/8" and the thickness as 3/32")
I use this on carpet the ones I've had in the past have always cracked on me after a few months. This one seems more "soft" and I don't see this happening so I'm happy with it. I may also add that it was the least expensive one they had. Go figure.
