I had a cheap mat that did not work out. I bought this one because it was thicker and worked out very well. Try it and you will like it I'm sure. Also was at a very good price.
We bought several of these mats to protect the new low pile carpet in our offices. We've only had them a few weeks but they are holding up well so far. The mats were curled up due to being rolled up for shipping but by the next morning they were flat.
I work from home and therefore my chair mat gets a lot of use. After 6 months of every day use it has several cracks in it. I am very disappointed. I noticed a small sticker on a new one in the store that there may be a guarantee for a year but if I had it I threw it away. Next time I will fill out the guarantee information. I still cannot believe it didn't last a year.
