FREDERICIA Mogensen 2208 2-Seater Sofa Børge Mogensen’s exceptional sense of proportions are at the core of this statement piece sofa. The Mogensen 2209. Capturing a key aspect of his design mantra, namely furniture with a calm aesthetic. Seen from the side, the quiet curve of the armrest and the gentle angle of the back are signature details that make this a simple, noble design. The Mogensen 2208 has all the same attributes in a 2-seater version.
