Knoll selects BASF’s Ultramid® nylon for its new Chadwick™ office chair

Furniture World News on

The recently launched Chadwick chair by Knoll, Inc., East Greenville, Pa., has attracted a lot of attention in the office furniture market for its easy, smart and comfortable design at an affordable price. Knoll selected BASF’s Ultramid SEG8 nylon 6 grade for this innovative hybrid seating design for its aesthetic and durability properties. Named after renowned designer Don Chadwick, the Chadwick office chair features simplified, easy-to-reach mechanisms to achieve “just right” adjustments for individual preferences, including the controls for seat height, tension, tilt stop, arms and lumbar support. The versatile style and scale are suitable for virtually any office or collaborative space. “Throughout my career, I’ve been striving to scale down what a chair is about materially,” said Chadwick. “I think the result is a Knoll chair that is very sympathetic to its ergonomic goals, but manages to bridge issues of materials and technologies, allowing a solution that’s light in scale. In the Knoll tradition of attention to materials and details, there is an emphasis on the overall quality of form and function.” BASF’s Ultramid SEG8 nylon 6 grade supports Chadwick’s vision for the chair design. This 40-percent- glass-reinforced resin delivers a “Class A” surface without the need for paint or secondary operations, and achieves a surface appearance that rivals materials with a smaller percentage of glass fill. However, the higher percentage of glass coupled with nylon’s inherent toughness results in Ultramid SEG8 nylon being better suited than comparable materials to meet Knoll’s rigorous durability and fatigue strength requirements for the Chadwick chair. In addition, Ultramid SEG8 nylon is easier to process than comparable nylons, achieving cycle time reductions of up to 40 percent and higher flow rates by 80 percent, which help lower production costs. “BASF was able to supply us with the right material formula for a complicated geometry and demanding aesthetics,” said Bob Melhuish, Senior Product Development Engineer for Knoll. “Ultramid SEG8 nylon is an excellent match for our material and structural requirements, providing the strength, structure and performance we need. BASF’s technical team also supported us throughout the design process, from nonlinear analyses of the chair arms to design of experiments on the prototype gas-assist tools. All our needs were satisfied.” According to Joe White, Market Sector Leader for BASF’s Engineering Plastics business in North America, Mack Molding, Arlington, Vt., utilizes gas-assist injection molding technology to run the Ultramid SEG8 nylon resin at highly efficient rates. He added that together, Mack, Knoll and BASF are meeting the Business and Institutional Furniture Manufacturer’s Association (BIFMA) Sustainability Guidelines. “BASF and Knoll share a commitment to sustainable design, which is reflected in the Chadwick chair design and our contributions to it,” said White. “Through the material solutions provided by BASF, Knoll is able to produce a chair that uses technologies such as integral coloring on plastic components and virtually zero VOC (volatile organic compound) paints. We also support the chair being designed for durability and ease of disassembly so that parts can be removed and replaced effortlessly with minimal waste.” Available in a range of neutral colors in warm to cool hues in the fabric, including beige, brown, silver, green and black, the Chadwick chair is affordably priced and complies with the BIFMA G1-2002 standard for fitting 90 percent of the population. Knoll’s Chadwick chair is designed to deliver optimized built-in comfort through its Active Suspension™ system for energizing and resilient ergonomic support, which requires minimal effort and need for adjustments from the user. Other built-in ergonomic features include a variable seat depth that automatically expands when sitting in the chair, forward tilt to support the user’s lower back when sitting upright, generous lumbar curvature and flexing arm pads that afford additional give to alleviate pressure points on the arms. The Chadwick chair also provides solutions that contribute to earning Leadership in Energy and Environmental Design (LEED®) credits, and uses raw materials with a recycled content of 41 percent. It is also GREENGUARD™ certified as a result of material selections and clean manufacturing processes.
