Mid-century interior design features clean lines, organic shapes, and functional aesthetics. Originating in the 1940s-1960s, it blends form and function with minimalist furniture, vibrant colors, and natural materials like wood and leather. The style embraces open spaces, bold patterns, and iconic pieces, creating a timeless, retro-modern atmosphere. With a focus on interior design, this style continues to influence modern interior architecture, offering a balance of beauty and practicality.
