I bought the new chair mat because mine was worn. This one does not do the job. My chair does not slide around on it at all. It sticks and I have to get out of my chair to move it from place to place. I have an L shape work station and it simply does not function. I would be better off just going without it and sliding on the carpet...
One of my problem was the difficulty in cutting this material to fit my desk space We solve the problem by picking up my desk and slide it under. I have a very heavy desk My chair rolls easy on it
