I had purchased a similar mat from staples 4 years ago. In the past 6 months it had started cracking. I feel 3.5 years for a mat that protected my carpet was a good life. I ordered this one again because I wanted a mat that was thick regardless of my carpet thickness.[...]
Better not to use these on thick carpet.I have med size rolling office chairs and using this matt over thick carpet isn't as easy as I expected. It's O.k. but there is drag. It's not unbareable and I'm not distracted enough to ditch the two I purchased and get two higher end ones yet. These are just O.k. I paid [$] on sale for each. If I could go back in time I would've sprung for the $40 ones. But until these die I'm not going to do anything.
