Material research primarily determines all of Jongerius’ designs. Her vast portfolio includes single pieces exhibited at galleries, mass-produced products sold at retail stores, design of airliner interiors and even the redesign of the North Delegates’ Lounge at the UN Headquarters in New York. Jongerius was just beginning her career when she was approached by Maharam and invited to work on a project for their 100th anniversary. Maharam now produces 29 different Jongerius textiles, many of which are in the permanent collections at the Art Institute Chicago, Cooper Hewitt Smithsonian Design Museum and MoMA. In addition to conceiving textiles for Maharam, Jongerius creates innovative works for clients of her own company, Jongeriuslab, and serves as the design director at Danskina, a Kvadrat Maharam company for which she dreams up rugs. She has a very clear idea of what makes a rug: "There are three components that have to make music together: interesting yarns, great construction and the right technique to give the pattern dazzling oxygen." Starting life as a color test swatch for another one of her rugs, Jongerius’ Multitone Rug (2014) demonstrates her genius eye for color. When asked why her colors look so beautiful together, she replies, "That is the secret of the color-cooking chef." The rich texture of Multitone comes from its flat handwoven basket construction, which she calls "the archetype of weaving." Made in India.
