During the next two decades, Haworth developed several industry firsts — from the first mobile office system to panel-to-panel cabling systems. Haworth also earned awards for its business and design practices, such as environmental sustainability, leadership, community service, and member job satisfaction. Under Dick's leadership, the company grew at twice the industry average. By 1980, Haworth had 830 employees and annual sales of $67 million. A year later, the company moved to its headquarters to One Haworth Center in Holland. Showrooms were open or renovated in 18 North American cities and four international locations. In the early 1980s, when office seating was added to Haworth product offering being built at the Holland, Michigan Haworth Plant, the company continued its movement toward providing complete workspace solutions. By 1986, Haworth had become the third-largest office furniture manufacturer in the U.S., with sales topping $300 million and a workforce of 2,600 employees. Along with the popular panels, products include office chairs, filing cabinets, and fabrics. Later in the 1980s, Haworth pursued an aggressive expansion in North America, Europe, and Asia. In 1988, Haworth became a global company, undertaking a strategic expansion. The business acquired 15 companies in Europe and North America, then built in Asia to expand its sales and dealer network. The reported $30 million acquisition of West German seating manufacturer Comforto GmbH made Haworth a multinational corporation, with factories in Germany and Switzerland. The first office to open outside the U.S. was in London.
