The Stockholm Furniture Fair in 2016 saw 40,000 visitors from around the world. Scandinavian design trends, which emphasize simplicity and functionality, continue to influence global furniture design. Mid-century modern styles from the 1940s-1960s are increasingly popular again. Natural materials like wood, glass, stone and metal are prominently featured. Plants and greenery are used to bring the outdoors inside and evoke a sense of nature.
