Kitchen Rug Set of 2 Anti Fatigue Kitchen Mats for Floor, Non Slip Waterproof Kitchen Rugs and Mats, Ergonomic Cushioned Comfort Standing Mats for Kitchen, Laundry, Office, Sink

There is absolutely nothing about these mats that are anti fatigue. In fact.. I'm fairly certain if I'd go to a dollar store I'd find better quality and thickness. As far as waterproof.. if you mean they act like a wick and suck up the water; then sure they are “water proof”.
