Hey there! Happy to help you with this. The provided information didn't include specific instructions, so I'll walk you through the general process based on how most manual recliner sofas are built. It's usually a pretty straightforward task!
Dismantling a manual recliner sofa is most often about removing the backrests from the main base, which makes it much easier to move through doorways. First, have a friend help you gently tip the sofa forward so you can access the back. Look for a seam in the upholstery on the lower part of the backrest where it meets the base.
You'll want to feel along the outside edges in that area, on both the left and right sides of each backrest you want to remove. You're looking for a small metal lever or tab on the metal frame inside. Sometimes you might need to lift a flap of fabric (often held on with Velcro) to see it. These levers are the locking mechanisms.
Once you find a lever, you typically need to lift it up or push it in. A flathead screwdriver can sometimes help if it's stiff. While holding the lever in the released position, have your friend help you slide the entire backrest section straight up and off its mounting brackets. You'll need to do this for the lever on the other side of the same backrest at the same time. Repeat this process for any other backrests on the sofa.
And that's usually it! The sofa is now in two or more manageable pieces. When you're ready to put it back together, you just reverse the process by aligning the tracks and sliding the backrests down until you hear them click securely into place. You've got this
