Material is soft so I am hoping that means it won't crack like the last protector I had but the softness makes it difficult to roll your chair on when seated as your weight creates dents in the surface.
much better than the smaller thinner "economy" mat I origianlly bought. The cheaper mat became brittle discolored and started breaking/shattering in the center where the chair sits most. This new mat is much thicker and more flexible.
