The way our bed is positioned in our bedroom, a wooden corner juts out right in to the walking path. Every few months I ram my knee in to it and vow to throw out the bed frame. I bought these one night right after running my knee in to the bed again. The color is a good match for dark wood and you wouldn't see them there unless you know to look for them. I have yet to hit my knee in to them, but with how thick and strong they are, I imagine my bruises and cuts will be a thing of the past! Great purchase!
