Hey there! That's a great question, as moving a bulky recliner sofa can be a real puzzle. The provided links didn't have specific details, but based on my experience, I can walk you through the general process. Don't worry, it's usually pretty straightforward!
Most recliner sofas are designed to come apart for easier moving. The first and most common step is to remove the backrests. Start by tilting the sofa forward so you can access the back panel. Feel along the seams on the lower back of each reclining section. You should find a fabric flap, often held down with Velcro. Peel this flap up to reveal the metal frame and mechanism inside.
Once you have access, look for the locking levers or clips that secure the backrest to the base. On each side of the backrest, you'll see metal tracks. There's typically a small metal lever or a black plastic tab on each track. You'll need to lift these levers simultaneously. Sometimes a flathead screwdriver can help give you the leverage you need. Once both levers are lifted, you can slide the entire backrest straight up and off the sofa base. Repeat this for each back section.
If your sofa has a center console, it often detaches in a similar way. It might slide up and out of its brackets or have its own set of release levers at the back. After removing the backs and console, the base sections may also separate. Look underneath to see if they are connected by interlocking metal brackets or held together with bolts that you can unscrew with a wrench.
Just remember to take it slow, and maybe have a friend help you lift the pieces, as they can still be a bit heavy. Taking a few pictures as you go can also be a lifesaver when it's time to put it all back together
