What Factors Influence the Best Size Pillows for a Sofa?

Several factors influence the best size pillows for a sofa:

• Sofa Size: The dimensions of the sofa itself play a crucial role in determining the appropriate pillow size. A larger sofa may accommodate bigger pillows, while a smaller one might require more compact options to maintain balance and aesthetics.
