This chair mat looks very good and works fine ... but after about two weeks on my floor I can't get it to lay flat. When I bought it it was rolled up. At first I had to weight it down for about a day to get it fairly flat. Now that its in position both ends still want to curl up. I've tried a heat gun hoping to soften the plastic but to no avail. My chair rolls fine on it it has a good appearance on my floor but I'm somewhat afraid of tripping on the slightly-curled end away from my desk.
looks really good very nice but it slide around on the floor under the chair but i still love them use them also for other thing like exercise mat also.
I got this to use on a beat up wood floor since it doesn't have the nubs on the bottom like those intended for carpet. The size is only 36 by 48 inches so it isn't ideal for large desks. However I just have a small narrow Sauder computer desk of the sort that is ideal for laptops. The short dimension is ideal for this desk and it doesn't stick out too far in the small room where I'm using it. . It began to lay flat after being unrolled only a few minutes. I haven't tried a chair on it yet but it looks ideal.
