My 2-year-old flipped out of this right away. We took it down after 1 hour. Our 1-year-old almost flipped out too and probably would have, if I kept it up. The walls are simply too low for this to be safe. Flipping out of it, my son snapped his neck. He was fine, but I was worried about what could have happened. Also, the two children crashed into one another all the time, hurting one another. Mainly due to wall height, this is an unsafe product. Sure, it was plenty fun for them. It's too bad it did not work out.Another thing to note is that there is a strong vinyl smell (which is supposed to be toxic, right)? In addition, the product is very large and didn't really fit anywhere without taking up a whole room. It takes a long time to inflate with an electric pump, so once it's up, it's up. Do not buy.
