Set up the mat in my home office put the chair on the mat. Hadn't even sat in the chair on the mat and there were already dents in the mat. Dents just make it harder to roll around in the chair
My old floor chair mat wore out. It was a pain trying to move my chair from place to place. This new one is thicker so the chair slides more easily and doesn't create "craters" in the mat due to my weight or the carpeting. Very smart move and love this mat. I easily replaced the old one by changing how I aligned this with my desk and I'm glad. Now I have wider movement easier slide and better access to my needs. I recommend this mat to anyone with a medium pile carpet who spends a lot of time at your desk.
