cut open the base, check the lower inner seat frame, and back of seat rail, if there are bolts through these the frame will be assembled in sections, removing these,arms first, then back bolts will enable the sofa to be de assembled and carried out much easier, if it s a full fixed frame, its struggle time basically.if you have to carry out a full fixed frame, remove the castors first to reduce door frame damage. a window can be removed and refit for £80 to £100, you could try to break it down, this won t be easy though....start with the arms first.
