Well, it seems the provided context was about as useful for this task as a screen door on a submarine, offering little more than YouTube's corporate information. So, let's set that aside and tackle this Herculean feat with a dose of common sense and sheer willpower.
So, you've decided to engage in the solo sofa shuffle, a noble quest for the stubbornly independent. First, you must prepare for battle. Treat your sofa like a puzzle; remove every cushion, pillow, and leg you possibly can. Every ounce you shed is a victory for your future self's spine. Next, become a master of spatial awareness. Measure your sofa, then measure every doorway, hallway, and tight corner on its path. There's no feeling quite like realizing your couch is permanently wedged in the hall.
Now for the main event. Your new best friends are furniture sliders. Get these magical little discs under the sofa's feet and you'll be gliding across the floor with an ease that feels like cheating. For corners, it's all about the pivot. Don't just push; lift one end and "walk" the other end around the turn. This is a delicate waltz between you and an inanimate object that has no interest in cooperating. An old blanket or flattened cardboard box can also serve as a makeshift slider on hard floors.
If stairs are involved, my sincerest advice is to reconsider all your life choices up to this point. But if you must proceed, your best bet is the controlled slide. Wrap the sofa in blankets to protect it and your walls, then carefully ease it down one step at a time, using gravity as a very reluctant assistant. Throughout this entire ordeal, remember to lift with your legs, not your back. And if all else fails, remember that a pizza is a surprisingly effective tool for summoning friends you thought you didn't have.
