One of the big decisions when considering living room seating is the choice between putting in a sectional and a sofa. Most people imagine the former to be a mammoth L-shaped leather couch that works only in giant living rooms. Nothing could be farther from the truth. The sectional sofa is suited to both large and small rooms, owing to the many different pieces that make up a typical sectional collection. All you need to do is choose the right number and style of pieces to create a set that matches your room size and layout. A good sectional not only accommodates all the seating you need in one fell swoop, but also multitasks by defining space and catering to all kinds of activities, from cat-napping to entertaining and watching television.
