This mat has rug grippers but not the nasty finger punching ones other products have. It only took about two days to settle in and not walk around as I move my chair. The delivery service was great.
Product is good. Offers good protection. Easy to mover around on. I should have gotten a larger version though. My chair rools off to the side of the mat and then the wheel gets caught under the lip when I try to get back on. Not a problem with the design. It was my lack of insight. Check out size requirements before you buy.
