The mat looks good and does what it should. It is approximately 2 mm thick, hard and very stiff - a roll down is impossible. (The mat is also provided for this reason, flat.) The bottom is smooth, the top slightly rough, which I think is optically advantageous. When walking or while rolling with the office chair you realize much of anything. (No impairment) Here also the hardness of the mat turns out to be an advantage, the chair does not cause bumps and rolls very smoothly and quietly on the mat. I use it on a dark brown laminate floor that is good enough to see through the mat and is well protected. An "anti-slip coating to increase traction" but I can not determine. The mat slips at least very strongly to laminate. But if they are, like me, may fix for example with a table leg or a roll container, then does not bother further. Still, I give it 1 point deduction, because it does not match the description. All in all I can recommend the mat but to protect sensitive flooring.
PS: A suggestion for the manufacturer would be chamfer or flatten the edge of the mat. This would possibly also help to avoid slipping when you roll with the office chair on the edge or otherwise remain somehow attached to it.
