While the provided search results mention instructional videos but do not offer the steps themselves, I can certainly guide you through the process. Giving your sofa a fresh new look with a slipcover is a wonderfully simple and rewarding project that you can easily accomplish.
First, you'll want to prepare your sofa by giving it a quick vacuum. Then, unbox your slipcover and take a moment to identify the different parts. Most covers have a tag indicating the back, which is your best starting point. Drape the entire cover over your sofa, aligning the back tag with the center-back of the couch. Gently pull the fabric down over the arms and the front, getting a feel for how it's meant to sit.
Once the cover is loosely draped, the real magic begins with tucking and smoothing. Starting from the center and working your way out, push any excess fabric deep into the crevices between the back, arms, and seat cushions. This is the key to achieving that smooth, custom-upholstered look. If your slipcover came with foam inserts or cardboard tuckers, now is the time to use them to secure the fabric firmly in place. If it's a multi-piece set, you'll then put the separate covers on your seat cushions before placing them back on the sofa.
Finally, secure any ties or elastic straps on the bottom of the slipcover to keep it from shifting. Stand back and make any final adjustments, smoothing out wrinkles and tucking any remaining loose fabric. With just a little patience, you'll have completely transformed your sofa and revitalized your entire room.
