Nice mat like the older ones. This one seems less stiff more pliable. Softer. That's seems good as the chair seems less likely to cause cracks. I've only had it a week. So the jury is still out. Great fast delivery. 2 days at regular rate.
This mat is quite thick and is great at protecting our carpet. We have tried mats available off the shelf and those were relatively thin resulting in carpet damage. The casters on the office chair would sink making rolling a challenge. This mat is much heavier and is better at holding its shape.
