It's weird these deck boxes give you a capacity in gallons since no one is going to fill these with fluids...  This deck box is enormous!  Not too difficult to put together, though the instructions are not very good.  You do need two people to do it, mostly because of the size.  Works well for us, fits patio furniture cushions for 4 seats (5" bottom 25x25 cushions, and slightly shorter thick back cushions, and a decent amount of room to spare (could probably fit cushions for two more chairs.)
