A collection, from Big Easy, a steel chair designed by Ron Arad in 1988, shows that a volume, a simple form, can be translated, without compromising the design principles, through a reinterpretation of materials and production processes. The model obtained from a constructive gesture becomes industrial production; the visual softness and fullness of the volumes, comfort. Big Easy explores the rotational molding and the use of polyethylene; the Soft version in the cold-foaming and, with the polyester fiber cladding, the transformation of the tactile surface; in the elements of the collection, the morphology, and the dynamic form. Frame in steel and stress-resistant polyurethane foam upholstered with polyester fiber. Spring collection covers are not removable.
