My old mat retired the impressions of the coasters for many hours. The physical size of the new mat was much larger than the replaced mat so maneuvering the chair was not limited.
This mat is thinner than I expected. I was by no means misled. I only assumed a carpet mat would be of a thicker material. My chair settles down into the carpet on top of the mat making it difficult to move around.
I am very disappointed with this mat. The material it's made of is way too thin and my chair sinks down into small divots when I sit for any length of time making it difficult to move.
