We bought these for our wooden coffee table and end tables. With our first child, these stayed on for about a year and a half. With our second child, we are having a hard time keeping them on there. She will pull them off when we are not looking and she's the one who needs the extra protection. Wooden tables are the least forgiving when a child falls on it. My nephew ended up with stitches because he fell and hit the table just missing one of these strips. I wish I had put these strips all along the sides. These are very dense and cushy. Both of my children would chew on them when they were cutting teeth and they never put a mark on them so they are very tough and durable. Effectiveness Very effective as protecting heads from corners. Ease of Use Very easy to use. You just put the adhesive strip on it and mash onto the surface. Quick and simple. Safety Safe for baby even if it gets pulled off. No choking hazards. Durability Really durable as long as your child doesn't pull it off.
