I specifically searched for Non Skid kitchen mats. And found the blue that I thought was perfect. The day I got them, I nearly broke my neck. As I put my left foot on mat, the entire rug slipped out from under me and I went flying. Luckily I was able to grab on to the island. At 82, I’m horrified to think what could have happened. I don’t understand how Wayfair can continue to use the “Nonskid” logo and get away with it legally. Shame on them.
