I wish it had been[...] "unrolled". I ended up with a pretty bad bruise on my leg trying to unroll it. Otherwise I am very satisfied with the product. It does dimple a bit but not enough to make it difficult to roll the chair.
This replaced an old mat that was not meant for carpeting. It was time for that to go and I needed something smaller than those oversized commercial mats. This fit the bill
Bought this to replace a high-pile (3/4") mat which cracked and disintegrated after almost 3 years. This one is larger in area (which I didn't need) and thicker. Of course chair wheels dent it but less than thinner products. There's no way to tell yet how long it will last. Previous product had a roughened surface for traction but this one is almost completely smooth on top with only slight pebbling. This makes for treacherous footing in stocking feet.
