We ordered the mat for our home office. While we are pleased with the mat it took a week for it to uncurl from being squeezed in the shipping box. Be patient - it's worth it.
This economy mat does what it is intended to do. It grips the carpet and does not move when you move your chair. I use it daily as I run a home based business from my computer. This is my second mat. I read reviews before purchasing the first one. Several people said it only lasts about a year. I found this to be true. After about a year mine started cracking in spots where the chair wheels gave the mat the most traffic. But for the price I bought a second one. I think a year's use is worth the price.
