This chair was maddeningly difficult to assemble.  Some of the  the metal tracks that attach the cushions to the frame are devilish to align and extremely difficult to separate to "start over".  The back cushion is now "locked"onto the frame at an angle of about ten degrees of tilt.  I gave up and left it that way.  I wasted about 2.5 hours with it and just gave up.  I am not inexperienced in such projects but this one got the better of me.
Otherwise, the chair is well constructed, but would be improved with newly designed attachment tracks.
