GREAT sandbox and my 2 boys (1 and 3 1/2) are in it all the time. Fairly easy to assemble (<1hr), although there were no instructions in the box. KidCraft is awesome though and they have assembly instructions for all of their products on their website.

Pros: Well designed with thoughtful storage areas. Attractive appearance
Cons: Canopy sags enough to allow for water collection during rainfall. Cover for sand is mesh, so you'll need a tarp to keep the sand dry
