Just wondering if anyone could give me any advice on the plastic mats that are put down for the chair to roll on. I clean an office that is all waxed floors and they have one of these under every chair. I sweep and mop the floors everyday, so it stays pretty clean. These mats are really annoying because they are hard to clean and the dirt tends to get under the edges and I think they just make the office look dirtier. Will it damage the floors if I remove these and just have the chair roll directly on the floors. They also are stripped and waxed every 4 months. Thanks!
