A plain sofa is not a problem until you start looking at it. Then it becomes the thing you notice every time you walk into the room. The fix is not a new sofa. It is almost always the cushions, and the specific kind of cushion that does both jobs at once is worth knowing about. Storage cushions give you somewhere to put the television remotes, the chargers, the things that live on the sofa because there is nowhere better for them. But the ones we’ve picked here go further than that. They look considered. The right texture against a linen sofa, the right scale on a sectional, the right color when the rest of the room needs something to pull it together. We’ve looked carefully at fill quality too, because a storage cushion that collapses the moment you sit near it is not doing either job well. These are the ones that earn their place on the sofa every single day.
