Definitely have more than one person when putting this together. Comes in 2 large boxes and so many pieces of different sizes. And there is a ton of hardware bags.. I would also say use the online (youtube) verbal and visual instructions, super helpful. Once the playground is put together its pretty sturdy. My husband and his brother tested out the swings!! One thing that i do wanna point out, is that its a little smaller than I  imagined, but still fits multiple toddlers/kids at once.
