Statements are easily made with furniture pieces of size. One of the largest pieces used in a given setting is the sofa. It is not surprising, that all classic modern sofas share a handful of design traits. To name a few, clean precise stitch or piping lines, squared and proportion similar back, arm and seat cushions and a low to the ground but considerable depth in seat combined with a mid to low profile squared back. Beyond the recognition of these similar traits, the pieces that have evolved to become classic sofa icons possess their unique individual design elements. Examples of such are the Le Corbusier stainless steel wrap around exterior frame and the Knoll Sofas button impressed patterned upholstered back cushions.
