Furniture interior design is the art of arranging and selecting furniture to create a harmonious and functional space. It involves choosing pieces that match the style, color, and feel of a room while ensuring they serve their purpose effectively. Good design considers the size and shape of the room, the natural light, and the needs of the occupants. Furniture should complement the architecture and enhance the overall aesthetic, making the space both beautiful and comfortable. This process transforms a plain room into a welcoming environment that reflects personal taste and improves everyday living.
