This deck box holds four extra large chair pillows and their pillow backs along with four throw pillows.  I transferred these pillows to the deck box in-between two rain storms.  The contents of the box remained dry.  It is supposed to be easy to set it up but I was tying to put the base on upside-down (don't try this at home folks!) so it took me much longer.  It would have gone together in less than five minutes if I hand't been such a dunder head!  Otherwise, great product!
