This was rolled up with the 'top side' to the inside. So the edges are still not lying flat. It has been more than a week and I've even had weights on the edges. This should have been rolled up with the top to the outside so when using it it would have naturally flattened over time. One of the edges also has a 'ripple' to it due to how it was rolled. Hoping over more time it'll get better.
I have purchased other carpet chair mats in the past that cracked within weeks of using them. A few years ago I tried this mat and it held up better than all of the others. If I can get two or three years out of a carpet chair mat I will be happy. I will continue to buy Staples brand chair mats in the future because they hold up very well and they are reasonably priced.
The mat is completely unsatisfactory. It came tightly rolled in a box. It was very difficult getting unrolled to be able to lay on the floor and even now the edges are still raised and are a tripping hazard. Otherwise it does the job rolling the chair on the carpeting.
