Very satisfied with this purchase.  I measured my patio cushions to make sure they fit and this box serves the purpose.  It is not water tight although, the cushions were left outside in the box all winter (purchased May 2016) and did not get wet from above.  There are gaps at the bottom; not sure if that is for drainage or maybe it did not go together well.  The box sat in the yard all winter and sunk into the dirt causing a little mud to get into it but it was very minimal.  Will be kept on the deck from now on.  Box lid does not latch down.  There is a place to put a small lock to keep it closed tightly but I just slid a long nail in the hole and it holds it down.  Fortunately, my son-in-law put it together so I can't say much about that.  He did not seem to have any problems.
