I have only been using it for 4 days and I already have ruts where my chair rollers sit. It is a real nuisance to roll around and I don't even have a very thick carpet! This is rated for medium pile carpet and it was supposed to have a lip which it does not which is fine with me. I wonder however if I received the correct mat. Regardless I plan on returning it as soon as I can. Also it was received with curled edges - I had to use a hair dryer to get them to flatten out. I'm not a happy camper as I don't have time for this!
Good chair mat for my medium pile carpet. I move a lot between 2 computer systems and this mat makes for smooth chair rolling. Not sure about long term durability but so far so good.
Nothing like trying to scoot around on your desk chair on carpet. NOT. Using the heavy plastic desk mat that anchors into your carpet without harming it saves the day. I can scoot from in front of my screen to the filing cabinet to the supply drawers with ease.
