Flash Furniture Jackson 45'' x 53'' Carpet Chair Mat with Lip

I'm super pleased with this chair mat. The other reviews made me hesitate before buying, but of course these mats are going to come rolled up: expecting anything else is unreasonable. My biggest concern is that I would get another mat that isn't very thick. These are problematic for several reasons, including that they'll start to crack within a year if on carpet. But not only is this mat super thick, it feels like it could last forever. It's also larger than the last one I had, which is a plus. Yes, it was a pain to unroll, but once I figured out a technique and got it stretched out, it stayed down. It still has mild warp waves from being rolled, but I'm pretty sure if I hit it with a hair dryer they'd calm right down. I really like how sturdy it is, and that my chair rolls across it smooth and fast.
