Not as thick as I though it would be but does protect the floor. I can still feel some of the ridges in the floor when I roll the chair while sitting on it.
Ordering was easy. Delivery was next day. Came unrolled and wasn't off gassing. All good things but I have a medium pile carpet and my chair started to sink in and make dents right away. I'm only 150 lbs.
Needed to replace a chairmat that had served for years. Staples had a similar size and reasonably priced mat. There were a variety of shapes and sizes displayed and available.
Works as advertised. I would recommend it for any in-home office. It's light-weight durable does not slide around on the carpet and blends in with the room décor.
