When it comes to finding just the right seating for a comfortable, laidback space, modern poufs are always a good place to start. They provide a decorative look, much like cushions, when not in use, but if you run out of couch space, you automatically have the perfect spot for a guest to sit.
Poufs come in any number of colors, so you can either match your existing color scheme, or use them to add a pop of accent color. You should also keep in mind that poufs are not just for the living room. While they may be useful for extra seating there, modern poufs fit in equally well in a playroom, nursery, or bedroom. You can really use them anywhere you might need a soft spot to sit or to add a little zing to your living space.
