My son was climbing down the ladder and fell on the concrete. He has some bruising and says his ribs hurt but I think he's overall ok. This got me thinking what can I put on the concrete so if a child fell they wouldn't break a bone. It's your standard A Frame ladder that is attached to the top rail. The way my backyard is situated its really the only place so moving the ladder isn't an option. I was thinking maybe a yoga mat but that is only 1/2" thick. Plus I was concerned that someone could slip and fall when those get wet. I measured the possible "fall" area to the left and right of the ladder and backwards and its roughly 5 feet by 5 feet. I need some good ideas TFP folks. Thanks!!!
