I really love this sofa!!  However, due to the lack of support under the cushions(the base of the sofa) the cushions started sinking after day two.  That
  Is with very light weight too.  Two young girls and me). Although I am really frustrated with it I love the sofa so much that I am now in search of a way to remedy the issue.  Sean and Catherine, my advise is to put some sort of boards across the bottom). It wouldn’t make it any less comfortable and the support would be there.
