rather thin.. advertised as for low-pile carpets but it's must need to be really tough flooring to work-- I've had mine 2 weeks and it has divots everywhere I try to roll my chair. It lost it's form within a day. Not worth the price-- I already need a new one
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")
CANNOT ANSWER THE CONS BECAUSE I JUST RECEIVED IT. Noticed that after a week and indentation where the wheel is leaves an imprint in the Chairmat. Hope it is not permanent.
