While certainly quite large, it fit cushions from a sofa and a rocker with some space left for possibly one more chair but it will be close.  My cushions are thick..Yardbird furniture.  So it would hold more from a set with thinner cushions.  The problem with this box and many resin boxes, is that screws from the metal frame screwed to the lid, pulled their way out of the resin lid.  Consequently, the frame bent.  I don't believe there is an easy fix for this as putting screws directly into hollow resin often do not hold up well.  Despite this, it is a heavy box and the lid is strong and heavy.   The assembly was not difficult as it was like a snap together puzzle until you come to installing the lid which does require two people but it is not difficult.
