This mat is much smaller than the one we had before. It is much too soft and gets pockets where the chair rolls over it. The edges also curl. Wish I had purchased another one like I had before. It was harder and larger. This one was a waste of money for me. I would only recommend using this on a concrete or no pile carpet.
The price was great but I wish it were thicker like my old one. My old one lasted for 10 years. I do not see this one lasting more than a year or two if I am lucky. It is too soft too so I am not sure if it is just the thickness or the rigidness that would make it last longer.
I thought this will be ok since my apartment unit has a commercial type of carpet the cheap quality. Based on the product description this chairmat is great for commercial carpets and not really suited for thick and high-end quality type of carpet. After only a few days of use it has already deep dents coming from the casters of my chair. It's probably just a matter of time that I will be seeing holes on the chairmat. Well I only paid [$] and it's just about the right price anyway.
