Sofa are to be found in the most social spaces in our homes. They must be flexible, provide seating for several people, function as a nest for a couple or a playground for a family with children. Decide what you need your sofa to be. If it is to be a lounging space for reading to watch TV, it must be comfortable. If you have children and pets, it must be durable and able to withstand the daily onslaught of both. And if the living room doubles as a guest room or a home office, it need to be able to convert in to an extra bed or provide extra seating space for meetings.
