Sofas literally bring people together. They are communal pieces of lounge furniture that encourage socialization and sharing of personal spaces. In laymen’s terms – they make you sit close to each other. From small loveseats to large couches to immense modular sectionals, sofas can be used in rooms of any size. Deep seated versions allow you to sprawl out in complete comfort, while fold out and futon style sofas convert into actual beds. Some industrial style couches incorporate riveted airplane metal, while deeply tufted leather is used to upholster the most posh and refined ones.
