The Marshmallow sofa was designed in the “Atomistic” style that is recognized in other George Nelsons designs such as the ball clock. Atomistic design explodes its parts into separate, brightly colored elements. In the Marshmallow sofa, the elements are the cushions that have the appearance of hovering or floating over the frame. If you’ve ever had the opportunity to try out a Marshmallow sofa, you are aware by experience that comfort and whimsical design can coincide.
