It took around 3 months for these to finally arrive. I don't know what happened, but it took a lot of emails and phone calls from Wayfair to me. I'm pleased overall. The treads seem a little thin, but the backing is wonderful. They do not move when placed on the steps. I do recommend them. I'm thrilled that these finally arrived, but they were "lost" 3 times in shipping. I am very happy that they finally arrived, as I do like them very much.
