I wish we had purchases this when my son was 12 months, now 21 months he is almost too big for it. It's much smaller than i anticipated and he prefers to play on it when inside rather than outside. Initially, I was going to return but he enjoys climbing and putting his cars down the slide. The basketball hoops easily detached and he actually enjoys taking that off and on so we decided to keep it and will pass it down to friends with littles when he quickly out grows it. It was easyto put together!
