A:Answer I can answer this question, cause I was shocked at how heavy it was. They delivered it to my address and I had my younger son take it to his brothers house (my grandsons are the older brothers kids). It was a good 3 feet tall, about 5 or 6 inches thick and about 20 inches wide. It weighed a ton. But the younger son said he didn't have a problem. I wasn't watching. So far, I only know that it was mostly metal, and the 4 balls were deflated. It came with an air pump to pump them up.
