The mat is too soft and the chair casters make depressions that don’t bounce back. So the mat has “pot holes” the makes it hard to move the chair around. Unfortunate since that’s why I bought it. ITT also moves on the carpet requiring me to constantly pull it back from the desk where it bunches up against the desk. We have a low pile carpet so that is not the cause.
Very good for our computer chairs on a low-pile rug. But since I am heavier than the wife I needed the thicker plastic chair mat. Guess I will be back at Staples getting another chair mat.
