Marco Zanuso’s exploration of support structures upon which to anchor the seat dates back to the design for an armchair entered in a MoMA international design competition in New York, in 1949. Starting with a matrix based on the geometry of the circle, in 1964 Zanuso crafted the Woodline design armchair with a wood skeleton that lends formal shape to the structure. Woodline has a removable cushion held in place with snaps and is upholstered in leather or fabric. The iconic Cassina edition features structure in walnut-stained walnut, panel in natural cowhide and leather tobacco-color cushions.
