We ordered this sandbox for Christmas, even though we knew it would be a  few months before it was warm enough to use in the backyard. My 15-month-old loves it already (even with no sand!). She climbs on top and feels like a big kid, then slides off. When I take off the lid, she'll climb inside or fill it with her other toys. I can't wait for the warm weather and see what she does when it's full of sand. The sandbox is a great size, sturdy and nicely constructed -- she can slide all over it, and there are no rough edges to worry about.
