Picked up the chair mat price is affordable but not as strong. When you are working all day in it it basically just dents the spot that you sat on for a long time. Not durable at all.
This item was described as appropriate for pile carpet meaning it won't slide or move easily such as when you.move a chair. That's not the case. I also have divots in the surface making it more difficult to move while in a wheeled office chair. I'll have to buy a new one when I can go into the store & examine it myself.
I was expecting a rigid mat that would keep my chair from sinking into the carpet but this one is very flimsy and flexible. In fact it's so thin that you can roll it up. My chair wheels make dents in it. It looks nice and is better than nothing but it definitely doesn't help my chair roll better or keep the carpet from being smashed. If there wasn't a pandemic I would return it to the store for something else.
