I liked the color and the material and really wished they worked for us but they moved all over the place and were not not slip at all. I tried applying carpet tape to the back to get them to stick to our stairs but the tape won’t stick to the rubber backs so it did us no good. The whole reason we got them was to keep me from falling down our stairs as I did while I was pregnant and ended up in the ER with air cast on my foot and leg. All in all these do not stay put on hard wood stairs.
