How do I use the rule of three to style a sectional sofa space?

To style a sectional sofa space using the rule of three, arrange three complementary elements around it—for example, a trio of framed prints above, three cushions with varied textures, and three side or coffee table accessories grouped nearby. Vary heights and shapes so the arrangement feels natural yet cohesive. This approach visually anchors the sofa, creating rhythm and balance without clutter. It simplifies furnishing decisions while making your seating area inviting and styled with intent.
