When there’s a party, they can be moved out of the way for better circulation, but for everyday use these extra seats help connect the sofa at one end and the pair of chairs at the other end. Be sure to use a pair of ottomans — not just a single one. When you have two sofas or any larger seating arrangement, a big coffee table might seem like the obvious solution. But also consider a pair of matching coffee tables. They will keep the focus off one large piece of furniture and let your eye move around the room more easily. One classic coffee table size is 48 by 24 inches, so you can plan on that when thinking about your furniture arrangement. A large coffee table is often double that: 48 inches square.
