The Diesis sofa is designed by Antonio Citterio & Paolo Nava for B&B Italia with support frame and feet in cast aluminum and steel tubing, available in polished brushed or black chrome finishes. Internal structure made of sheet and profiled steel, shaped polyurethane upholstered in leather. Seat cushion padded with multi-density shaped polyurethane, viscoelastic memory foam, and sterilized down; back cushion combines shaped polyurethane and sterilized down, while the armrest cushion is filled with sterilized down and upholstered in either fabric or leather. In the leather version, the upholstery of the structure and that of the cushions is the same. Diesis is available in two sizes, with either a single or a divided seat cushion.
A celebrated icon of modern Italian minimalism, Diesis was first introduced in 1979 and has now marked over 45 years of enduring design legacy—remaining a benchmark in high-end interior furnishing. This is a sofa that masterfully balances form and function, designed to be both admired and lived in.
Diesis brings together cutting-edge technology, pure elegance, ergonomic precision, and superior comfort—embodying a true symbol of contemporary design. Its defining structural element is a cast metal frame with an internal perforated steel bar, providing elasticity and strength while precisely outlining the soft, sculpted cushions that envelop the seat, backrest, and armrests.
A signature detail is the generously wide leather-clad armrest topped with a plush down cushion, offering both comfort and visual appeal. The backrest features an elegant comb-like structure in harmonic steel wrapped in leather, while the die-cast aluminum feet and accents lend the piece a bold character and distinctive material identity.
Striking from every angle—including the fully leather-upholstered rear—the Diesis is designed to be placed at the center of a room, transforming it into a sculptural and scenographic focal point.
Crafted with a blend of artisanal techniques and innovative technology, Diesis is made to meet the highest international design standards and built to last. A timeless aesthetic meets advanced functionality, delivering exceptional comfort through its sophisticated mix of memory foam, sterilized down, and multi-density polyurethane—offering a seating experience that is both generous and inviting.
