“As a company, we manufacture in the markets where we sell our products,” Chairman Emeritus Dick Haworth said. “Our plants in China aren’t there to supply the North American marketplace, because they supply the Asian market. It means we have high-quality jobs in all of the markets that we are involved in.” The company grew dramatically in the 1990s with the acquisition office and business furniture makers around the globe such as Mueller Furniture Co., Kinetics, and Lunstead. Haworth almost quadrupled in size in the early 1990s, while the percentage of income spent on sales, administrative, and other expenses went down significantly. By 1990, Haworth had 4,240 employees and $600 million in sales. The next year, it reorganized into four regions: North America, Europe, the Middle East/Africa, and the Asia Pacific & Central America/South America. In 1992, Dick's son, Matthew Haworth, formally joined the team as a dealer associate — the same year Haworth became the first furniture manufacturer to achieve ISO 9001 certification. Haworth reached $1 billion in annual revenue in 1994. In 1995, the company's Ideation Group formed, applying user-based research to breakthrough concepts and products such as Crossings, Irrigator, Flo, Eddy, Drift, and Wake. That same year, 30 percent of sales come from overseas.
