This is the best box. I got it for my Cottage on the Chesapeake Bay to store large chair cushions on the deck. They fit perfectly in this size, as other reviews have said. We nailed this down because of storms we tend to get over the water, so it's now been outside for a year and looks good still.  It actually is waterproof. Even without putting a lock on it, the top stays shut.  Terrific.
