Well, it seems the context you provided decided to give us a grand tour of YouTube's legal disclaimers and wikiHow's main navigation rather than the juicy details of sofa disassembly. As thrilling as copyright law is, it's not going to help us get that beast through the door. So, let's rely on some practical wisdom instead.
Taking apart a reclining leather sofa is a noble quest, usually undertaken just before the realization that it will not, in fact, "pivot" through a 30-inch doorway. Your first and most crucial target is almost always the backrests. They are the key. Feel along the back of the sofa, down in the gap where the back cushion meets the main frame. You're on a treasure hunt for small metal levers, one on each side of the seat back. Sometimes you have to lift a flap of leather or fabric to see them. Once you find a lever, pull it up or push it down, and the back should unlock, allowing you to slide it straight up and off the metal tracks.
If your sofa is a multi-part sectional with a console in the middle, it's time to look underneath. Gently tip the sofa forward onto its face. You'll likely see that the separate seating sections and the console are held together by bolts or a system of interlocking metal brackets. A simple wrench or screwdriver is usually all that stands between you and victory. Unfasten these, and the sofa will break down into more manageable, though still awkwardly shaped, pieces.
When you're done, you'll have a pile of sofa parts that look much less intimidating than the original behemoth. Reassembly is just doing everything in reverse, assuming you kept track of the screws and your sanity. Good luck, and may the moving gods be ever in your favor.
