We bought this for our (then) 9 month old who seemed to have a serious climbing bug. After a few days, he was climbing up and sliding down all by himself. It was so neat to see how quickly his skills improved and how proud he was of himself. It was super easy to assemble and has such awesome features. Our little guy also loves to roll, throw and kick balls, so the football, basketball and soccer ball were great additions. He just turned one, and it is still one of his favorite toys. I would highly recommend this to any parent with a little explorer.
