At the beginning of the summer I bought my kids (3 and 2) and Little Tykes Moonwalk. I looked up a lot of reviews on them and wasn't too impressed. A lot of people said it was too small for a 4 year old. Well, my 3 year old is big for her age and has plenty of room to jump around. She will probably use it for the next couple of years. My kids are very rough and have not broke the moonwalk yet!! It comes in a small bag that is very easy to store! It was a great buy!!
