The deck box arrived intact in a sturdy box.  Assembly was very easy and I was able to do it all myself except I needed somebody to hold one side of the lid while I fastened the other side to the piston hinge.  My 8 year old son assisted me with holding the lid. It was a little tricky to snap in the last two connections on the end but I quickly did it with two pieces of 2x4 to distribute the load and a bar clamp to apply the pressure.  My 260 of weight were not enough to snap in those last couple of connections.  Overall it took less than an hour to assemble and that includes unpackaging, assembly and putting tools away and breaking down the box.
