A lip edge or tray top on a coffee table is always a smart choice if you have a tendency to spill your coffee or have kids that will be using the coffee table for snacks and drinks. They’re also good if you entertain often and don’t want to worry about red wine getting spilled on your carpet.
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.
