You can’t talk about sofas and cosiness without mentioning cushions and blankets. They’re the cuddly elephant in the room. Creating different layers of textile makes things cosier for a few reasons. It emphasises the use of fabric so that when you walk into a room and look at your sofa, you’re reading softness, softness, softness. Even if you don’t immediately recognise it, when you look at a cushion-laden sofa, you’ll think about leaning back in them, or resting your head on them, or having one on your lap and letting your arms sink down into their feathery depths. Not every cushion needs to be different. If you choose a few in the same fabric, it can look like one big, tempting cushion. Just make sure you add in one or two others though, otherwise you’ll have no definition. Contrasting throws are much better than having two of the same. They act as a foil against one another so they both get noticed, which is exactly what you want if cosiness is the goal.
