Ah, the great recliner-moving puzzle! It seems the provided context is about as helpful as a screen door on a submarine, offering only YouTube's legal boilerplate instead of the juicy details you need. Fear not, for I shall be your guide in this noble quest of furniture disassembly.
First, you'll want to prepare for battle. Tip the sofa forward so you can access its mysterious underside and back. Most 2-seater recliners are designed to come apart in a few key pieces, primarily the backrests and the base. The magic lies in finding the release clips. Feel along the back of the sofa, in the gap where the bottom of the backrest cushion meets the main frame. On the outer metal frame of each seat, you should find a small metal lever or a black plastic clip. Sometimes they're hiding shyly behind a flap of fabric.
Once you've located these elusive levers, the rest is a matter of finesse. Using your fingers or a flathead screwdriver for stubborn ones, pull or push the lever to unlock the backrest from the base. With the lever released, the entire back section of that seat should be able to slide straight up and off its metal tracks. Do this for both seats. You'll be left with two surprisingly manageable backrests and one much less intimidating base. The base itself rarely comes apart further, but having the backs off usually solves 99% of "it won't fit through the door" crises. Now you can move your deconstructed throne with the grace of a seasoned furniture whisperer.
