A., I actually purchased this foam just before my daughter could crawl (about 2 years ago). I have a raised hearth that is rectangular and it scared me to have her stumble on her wobbly legs or get accidentally knocked over by our dog when she was near it. So, I searched everywhere for something that would protect the entire fireplace, rather than just the edges. And, I, like others, considered blankets, pillows, etc, but I didn't think it would completely protect her from hitting a corner some day.
Anyway, I bought the Baby Safety Foam and have been so pleased with it. I NEVER have to worry that we will take a trip to the emergency room because of a fall on our fireplace. Plus, in the winter we can still have a fire in the fireplace with the foam still in place. Most people don't even know the foam is there when they come in to our house. It blends in so well. I put some of my daughters toys on top of it and it is the perfect height for her to play or reach her book bin. Plus, I know now that when other children come over to play, I don't have to worry about them getting hurt on our fireplace either. I'm sure I could have trained my daughter, over time, to be careful around the fireplace, but now I have the peace of mind that both her and anyone else are protected from a bad cut or injury. It will be the best money you spend on a fireplace guard and they guarantee your satisfaction on their website. Depending on where you live, you are welcome to come take a look at mine. Email me and I'm happy to answer any other questions. Good luck!
