My adult son assembled it. All of the pieces were there and it looked great. Yesterday two of my grandchildren came over and we played in it.  I had purchased some toys for playing in sand. We had so much fun! The two plastic containers were filled with water. We put sand in molds, added some water, and turned the molds over...presto we made many sand objects. They loved the feel of sand on their feet too. Great sandbox.  Love it!!
