Bertoia Side Chair with seat cushion surpassed my expectations.

By: Debra V. (austin, texas)

I was familiar with the Bertoia Side Chair, but the opportunity to sit in the chair had not presented itself. I was a little nervous about the wire back and seat in terms of comfort. Turns out it is very comfortable...use it at a desk with laptop....smaller in proportions than I originally that also...just a beautiful chair! I liked the fact that ordering the chair at Yliving eliminated taxes and shipping costs. However, I had to wait almost 3 1/2 months for the arrival of the chair. That's a long time.

Harry Bertoia

Designer: Harry Bertoia

Italian sculptor, university lecturer and furniture designer Harry Bertoia displayed a unique stroke of genius with his patented Diamond Chair for Knoll International in 1952. Bertoia was an inventor of form and an enricher of furniture design with his introduction of a new material: he turned industrial wire rods into a design icon. Educated at Detroit Technical High School, the Detroit School of Arts and Crafts and Cranbrook Academy of Art in Bloomfield Hills, Michigan, Bertoia taught metal crafts at Cranbrook. He worked with Charles Eames to develop his signature molded plywood chairs. Eero Saarinen commissioned him to design a metal sculptured screen for the General Motors Technical Center in Detroit. His awards include the craftsmanship medal from the American Institute of Architects, as well as AIA’s Gold Medal.

Manufacturer: Knoll

Brand Beginnings Knoll was founded in 1938 by Hans and Florence Knoll who sought to create new types of furniture and environments for the home and workplace. Their approach was to join craftsmanship with technology through the use of design and to create beautiful home furnishings that stood the test of time visually, functionally and practically. The pair sought out designers willing to change the landscape of modern design, daring to ask how furniture could work better. These landmark collaborations, with pioneering modernists like Eero Saarinen, Ludwig Mies van der Rohe, Harry Bertoia and Richard Schultz built a brand that today contains many of the hallmarks of modern design.

Knoll Today Knoll enjoys brand recognition throughout the world for its modern classics as well as groundbreaking new products formulated under new deigner partnerships. Few companies can match the array of Knoll products, which combine a modernist aesthetic with residential appeal. This point of view nurtured by Florence Knoll, has become the trademark of Knoll design. Today, it connects to a new generation seeking workplaces and homes that are comfortable for and beautiful for everyday living.

A Signature Piece The highly coveted Barcelona® Chair is, with little doubt, the signature Knoll piece. Designed in 1929 by Ludwig Mies van der Rohe, it is one of the most recognized objects of the last century, and an icon of the modern movement. Skilled craftsman construct this exquisite chair by hand every day. From leather produced from a single cowhide, 40 individual leather panels are cut, hand-welted, and hand-tufted with leather buttons to upholster the chair. Premium cushions are highly resilient with a down-like softness that surrounds the sitter in luxurious comfort. Cushions are suspended by upholstery straps in cowhide belting leather over a metal frame that is hand-ground and hand-buffed to a mirror finish. Meticulously detailed, Barcelona continues to appeal to customers worldwide some 85 years after its introduction.

Why Knoll? The Knoll names offers a rich design history – a legacy of iconic designers and inventive new collaborations. Their focus on quality and responsible manufacturing means that each piece transcends multiple generations in both use and appeal. Knoll offers furniture, accessories, textiles, felts and leathers that stimulate the senses and allow you to express who you are and what you value. They take great pride in creating the best possible product and the happiest possible customer.
