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.
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.
This works exactly as expect. The product arrives folded once over which creates a crease that needs some pressure to flatten out but ultimately causes no problems.
