Hi Dennis,
Yep, the sofa will go out the door. Here's a link to a response by Scott on that question.
As for the chairs, if they are they same Flex-Steel units that are used in the Landmarks, the answer is yes as well. Open the Velcro'ed flaps on the back, open a tab on each side and pull up on the back - it will come off. Those swivel rocker bases are heavy!
Best of luck.
Jim
