I have this mat at the office and it has held up quite well so it was a clear choice to bring into my home office. It arrived rolled but flattened within 24 hours. I’m happy with this purchase.
I've only had this mat about a week so some things - like durability cannot yet be judged. So far 1) Folks complain these mats often come rolled up in a box and are difficult or impossible to get to lie flat. This one came on a Staples truck and was flat. It was left on the front patio where it did take on a bit of a bend because of where it was placed. However I laid it in the 95 degree sun for an hour and it was like a limp cloth. Put it inside on a cooler hard surface to let it cool off flat. Then under my chair. 2) Some have also complained these mats have an odor. This one had a slight odor immediately after bringing it in from being in the sun. However once it cooled it seems to have no odor. (Wife has a very sensitive sniffer and she's not said a word about an odor.) 3) The "cleats" on the back are doing an OK job of holding this mat in place but no better than the spikes on my previous mat. (Doing the paperclip test the carpet depth to the backing is 1/2". Of course pad under that also about 1/2" I think.) 4) The mat is soft enough that it dents from just the weight of my 4-wheel oak desk chair. However the dents do not seem severe enough that they prevent me from rolling around on it. Not as smooth as say smooth hardwood but a) better than on the carpet and b) better than on my old on which was falling apart. Bottom line seems a decent mat for the price. Gave it 4 stars because of the cleats not holding as advertised and because of the denting.
