A plain sofa is not a problem in itself. The problem is leaving it that way. A neutral base is actually one of the best things you can work with, because the right cushions will do more to change how a room feels than almost any other single purchase. We think about fabric first. Velvet holds colour beautifully and photographs well, but linen and textured weaves are the ones that tend to look right in real life, in real light, over time. We also think about proportion, because an undersized cushion on a generous sofa looks apologetic rather than considered. What we have picked here are the cushions that bring something specific, a colour that anchors the room, a texture that adds depth, a pattern that stops things feeling too safe. Not just decorative filler. These are the ones that make you look at your sofa and feel like you finally got it right.
