Many people add side tables only when they feel there is an empty corner or a missing piece. That approach rarely works well. A table placed just to fill space often ends up looking disconnected from the rest of the room.
Instead, think about what the space needs at that exact spot. Maybe it needs a pause between the two seating areas. Maybe it needs a surface that makes daily use easier. A good side table design for a drawing room always solves a small problem while improving the overall look.
