This wagon requires a little bit of elbow grease to put together. You'll need a hammer, screwdriver, pliers, and a wrench. It's made of an okay, but not high, quality wood. The sides slip in and secure only in the slot on the bottom. When the kids lean back on it, the sides push out a little, but I'm not worried about them breaking. The weight limit is 80 pounds though, and it's probably wise to stick with that. Our kids love the wagon. It's easy to steer and relatively sturdy. It probably won't last as long as the old metal wagon I had as a child, but it'll do.
