Seems a bit flimsy so not sure how long it will last but the price was right and replacing it at that price after a couple years would not seem to be a problem.
A chair with rollers in any one spot for more that a few minutes on this chairmat develops a sinking spot. It is not thick enough for a chair with rollers on carpet. I weigh 160 and my chair is around 25lbs. That should not happen.
