These cushions will get in the way while you're separating and moving the couch sections. They also may cover the handles you have to grab that separate the pieces. Start by removing the cushions so you can access all the handles. If you're moving the couch, put all the cushions in a safe place out of the way. Someone could trip on them if they're too close. For some sofas, specific cushions belong on certain parts of the couch. If this is the case, keep track of which cushions belong on each section. Some couches have attached cushions that aren't removable. In this case, just find the corner to begin disconnecting the sections. Push the cushions aside as much as you can to see if there are handles. Sectional couches usually meet at a square corner piece that forms a focal point. Both sections connect to this square. The rest of the couch will come apart when you disconnect this corner. Many sectional sofas have a designated place to lift from. If the square corner has a plastic lip around its rim, slide your fingers under this. Then lift straight up to detach this piece from the other sections. If your couch doesn't have a handle, just grab a stable spot and lift. Different sofas use various connection methods. Some have clasps that slide together, while others have hooks that unclip. In most cases, however, lifting straight up is the procedure for disconnecting the pieces. Make sure the corner disconnects from both sections before you try to move it. Pulling on a section that's still attached could rip the sofa. Most sectional sofas have only 3 piecesthe corner and 2 attachments. But on some larger sofas, the sitting sections also detach into multiple pieces. Check along these sections to see if there are any gaps indicating they detach. If they do, lift these sections straight up to detach them. If you aren't sure if your couch breaks up into more pieces, consult the manual that came with the couch. If you didn't save this manual, try doing an internet search for the couch brand and model.
