Review on HemingWeigh Office Chair Mat with Lip: Anti-Slip PVC Carpet Protector for Gaming Chair & Rolling Chairs - Set of 2 (36 x 48 Inches) by Justin Vasquez

I really like the thickness and strength of this and it would be exactly what I want. HOWEVER, I hate to bitch, but this is practically useless. I can't get him to lie flat. I literally tried everything I could think of. I put weights on it, put a heat gun on it. Turned on the heater in the area where I have it. Nothing, it's lying on the hard floor in the garage. Because it's grooved, it stops me from rolling and when I try to roll everything moves. Yes I read the reviews but I seriously thought it would smooth out over time. It's been two weeks and no.
