Well we are kid proofing. We bought one of the kidco hearth gates for the fireplace. But ended up using that elsewhere in the house. I have a good screen that latches onto the fireplace, which should be good (Havent had the fireplace going, it on, and her around, so we will have to see if I need another official gate or not). But the question is: The fireplace is an insert, with a traditional hearth, about 12" up and 12" out (or there about) and I want to put the foam pad stuff on the edge to minimize the damage when you hit it. The reviews on amazon are all great! BUT those people dont use their fireplaces. I heat my house with it. Has anyone tried that stuff with good results? How about removal, i assume thats not going to be an issue since its slate. Thanks!
