Here is a great curvy sofa from Lee Jofa furniture. The striking thing about this piece is the use of curves to define its overall shape. First there is the curve from the middle out to each end. Then there is the gentle slope of the back rest as it flows down into the arms. The arms of the sofa embrace curvature thereby supporting the overall design theme. A lot of couches may be boxy, but the Lytham sure is not.
