This mat is pretty good the one we had forever finally was breaking and we needed a new one for the office. This one fits perfect for the smaller desk. It seems to be doing pretty well.
I purchased the quill brand exonomy carpet chair mat and it is working great. I does not move on the floor and the chair rolls easily. We have very dark carpet and the light reflects off the mat to help lighten my work area! It's great.
These mats seem to be holding up just fine so far. You get some wheel indentations when sitting for a while but not too bad (low pile carpeting). I don't think any of them would be Perfect. Much better than the thinner/cheaper ones we've purchased in the past.
