It is fine for my needs. I can tell that it probably won't last all that long but I am using it for my home office while working remotely because of the pandemic and didn't want the new carpet in my office damaged. The size was perfect for the space I needed to cover. It does tend to bow under the weight of the chair and all the COVID weight that I've gained.
This mat gets divots where my chair legs meet the mat. This prevents me from rolling forward or back. I believe the plastic is too thin. The mat is on top of Berber carpet and jute padding.
This is the second Chair Mat I have purchased after many many years of home use. with the first chair mat. The larger mat size I have liked as it provides greater coverage of my work space and stays in place. Downside: small divots occur where chair wheels rest.
Chair Mat was delivered on time at a very good cost. Since it was not rolled up like others I've seen online it was easy to remove and replace my old mat.
