They work really well. I was skeptical at first but they are very comfortable. We have always had carpeted stairs but when we got rid of our carpet, we changed out our stairs to wood. I was always feeling a little unsure about the wood stairs. I thought I would slip. I purchased these stair carpets and at first I thought they would not stay in place but they are really nice and definitely make it much more comfortable and safe. They stay in place perfectly.
