We tried out a tunnel at a Gymboree class and she loved it. I like the mesh so I can see what she is doing without sticking my head in. I have it propped between pillows so it doesn't roll as much. My daughter is 7 months old and it looks safe, I am not sure what small pieces they are referring to on the warning label. My sister gets in the tube with her and chases her out. It folds down easy and doesn't take up a lot of space. Using it indoors when we are forced to hibernate for the winter!
