I bought this to replace one that had cracked. It was three years old. This one does not seem as sturdy. Feels so much thinner and is much lighter. I'll see how it holds up.
I used this under a rolling chair in my hobby room. It is smaller scale than some I've looked at and so it fit nicely. It grips the carpet well and stays in place. I had a coupon for 25% off so it was a good bargain for me and my use
Felt pretty heavy duty in the store. My carpet is only 1/2" thick but mat dimpled where chair sits almost immediately making it very hard to move the chair. Was supposed to be good for carpets up to 1". I only weigh 170 lbs and my chair has 5 rollers. Very disappointed.
The size is a perfect fit. However I don't know how they are rated for carpet thickness. This mat was rated for 'medium-pile' and I thought it would be extra heavy to use on my 'low-pile' carpet. It was not. Though rolling is easier it does dent if I sit in one position for for a minute or two also because it is so flexible even with the cleats the mat creeps. I'm concerned that the constant flexing will cause premature cracking.
