Mid Century Modern and Scandinavian are two of the major trends in interior design in America and Europe, with iconic creations like the Barcelona Chair (van de Rohe) and the Shell Chair (Wegner) as its achievements. You can say that Scandinavian and Mid Century Modern are related. Just from a visual point of view, it’s very common to appreciate that Mid Century Modern pieces look Scandi, and vice-versa.
Mid Century Modern made its appearance in the 1950s when the Scandi movement already had at least 10 years in the making. The greater minds behind what we call the Scandi movement, like Hans Wegner, Arne Jacobsen, Eero Arnio, and Ingvar Kamprad (the famous founder of Ikea), are names considered both parts of Mid Century Modern inheritance, and Scandinavian as well, by each group of scholars and designers.
Just like Mid Century Modern, Scandinavian share the taste for minimalism and functionalism over ornaments, but looking at the answers mainly in their master and craftsmanship with wood. One fine example of this approach is the Shell Chair, of Hans Wegner.
On the other hand, Mid Century Modern looked for quality design to be at the reach of most of the people. It embraces minimalism as well but differing from the naturalist approach of Scandinavian.  MCM masterminds prefer to use the giant resources of American industries, where metals, polymers, and plastic fiber made cheaper work to get any furniture. One great example of this is the Barcelona Chair, created by Ludwig Mies van der Rohe and Lilly Reich.
