Soft curves create welcoming, approachable spaces central to fall 2025 interior design. Rounded sectional sofas, curved armchairs, and arching furniture edges replace hard angles to promote comfort and flow. These shapes naturally invite relaxation and complement earthy palettes and layered textures. Emphasizing soft curves over sharp lines transforms rooms into tactile retreats, matching the season’s mood of warmth and personal style. Adding curved furniture pieces helps your home feel effortlessly inviting all fall long.
