One can only give an early review of this item as the real question is how it will stand up over time. Right now it looks great. It shows imprint of chair rollers and then the depressions spring back to normal after the chair with my weight in it has been removed. My only other minor issue was method of shipment. Apparently they are removed from place of storage and placed on delivery truck unwrapped and unrolled. Mine had several black footprints on it that I had to clean off with Windex.
Purchased this carpet chair mat to replace a chair mat showing signs of wear/tear. My old mat had flat/square edges. This new mat is great!! Its smooth edge ramps down to the carpet. It stays in place with no sliding around on the carpet. Its the same size as my old mat. I am very pleased.
