For me, good modern design is more than just a sofa that looks good, it has to be functional. For those of us who's homes and apartments are square foot challenged there is no more important function than storage. That is one reason that I love this Tweed Storage Sofa from Urban Outfitters. It has a classic retro/mid-century modern lines and a pleated tweed pattern that complements its sleek low stance. Speaking of functionality, not only does it have storage, it also folds out to make a bed. Not too much more you could ask of a sofa, especially at $580. Available at Urban Outfitters for $580.
