A “box” joint coffee table

Well this was one of the more frustrating projects I have built to date.  I love the final product but I question the day I decide to build a completely box joint piece of furniture.  The project was entirely constructed out of a bundle of unfinished flooring from the depot which made it challenging due to the random length of boards.  I hope I can find a source for lumber here in NJ that would make these projects more affordable and with higher quality lumber.  The piece is designed to have pillows on top as cushions for use as a foot rest and a coffee table when removed.  I think it is time to upgrade the table saw to something more suited for furniture building.
