Its intuitive adjustments and holistic ergonomics deliver comfort without fuss, and an updated palette of color and material options engages a contemporary vision.

Bruce Hannah has made a career of mastering modern technology and materials to create efficient, practical products. “I’ve been on a personal crusade to create as much softness in the world as I can,” says the Pratt graduate and tenured professor. He believes in using as little material as possible and aims to round all the corners in the world.
A graduate of Pratt Institute, Andrew Morrison brought clarity and economy to everything he designed. His furniture was made with the most appropriate materials, efficiently produced, and designed to adapt as the patterns and technology of the modern office changed. This approach resulted in several award-winning collections for Knoll.

Knoll has lived their guiding principle, "good design is good business," since 1938. Products are all created to inspire, fit, and last. The Bauhaus philosophy that furniture should complement, not compete with architecture, is central to Knoll’s design. Its extensive portfolio includes office work systems, residential mid-century modern classics, textiles, and accessories.
Designers like Harry Bertoia, Eero Saarinen, Warren Platner, Isamu Noguchi, and Florence Knoll contributed to Knoll’s iconic designs. Knoll invests in research and field studies and explores organizational behavior and technology to ensure quality excellence. As a leader in sustainability, Knoll’s practices reduce waste and conserve resources. Based in Pennsylvania, Knoll has a strong international presence, and 40 products are in the permanent collection of the Museum of Modern Art in New York.
