Designed by Patricia Uroquiola and made in Italy by B&B Italia, this steel, polyurethane, plastic material, and leather sofa is part of a modular compact seating collection for reception, lounge and meeting applications. The collection, called, "Hollow" boasts concave plastic panels which enhance the appearance of the lightness and give the collection its name. Numerous variations in finishes and dimensions allow the Hollow collection to be specified in diverse variations with alternative monochromatic or contrasting aesthetic options.
