Have had this mat for less than one week & it has already slid on the carpet and has bent. I've tried to manipulate the vinyl but to no avail. Also there are wheel indentations in the vinyl. I thought the last mat I had was terrible this one is even worse. The first mat I had lasted more than 10 years. I will be happy if this one lasts a year.
Perfect size for the "L" shaped desks we ordered. Chairs roll over it smoothly and stays in place. Have had them for 9 months and they are holding up well.
