Bought one of these about 6 years ago and it's cracking enough now that it needs to be replaced. Just ordered a replacement today. It does get some indentations in it where I tend to sit and the chair wants to roll into them but unless you're one a completely solid surface like a big sheet of wood or metal it'll happen. All in all it's a good chair mat. Hope the new one lasts this long too!
I thought that the small square nubs instead of the sharp spikes would not hold so well and I was right. After two or three days of moving around in the chair the mat moves and needs to be repositioned. Also the materail appears to be too soft and just the weight of the chair alone leaves imressions. Not too happy with this purchase.
just as advertised cheaper than anyone else and no delivery charge and my chair is currently on the mat as I type it performs wonderfully. Item arrived in a very timely manner
glad we got it. Works as intended. Nothing fancy. Needs to lay out for a day to uncurl. Then it's good to go. We have pretty standard office / commercial carpeting and it worked perfectly.
