Leave room to move.
One of the secrets to learning how to arrange furniture is making sure you leave enough space between pieces. Allow 30 inches between furniture you need to be able to walk around and 14 to 18 inches between a coffee table and sofa, so drinks are within reaching distance.
Use the right side tables for your space.
Use round pedestal tables as side tables between chairs and sofas. The curves of round tables make them easier to navigate around. When space is tight, use nesting tables for flexible use when needed.
