The three main brands of Steelcase Inc. are Steelcase, Coalesse, and Turnstone. The company also has several other brands and subsidiaries, including Designtex and Steelcase Health and Education. Steelcase acquired Designtex in 1988. Designtex offers interior textiles and upholstery. The company established its office accessories brand, Details, in 1990. In 1993, the company launched Turnstone, a line of furniture designed for small businesses and home offices. In 2006, Nurture was founded to create products for the health care industry, including furniture and interiors for waiting rooms, offices, and clinics. The brand became Steelcase Health in 2014. Steelcase merged three of its subsidiaries, Brayton International, Metro Furniture and Vecta to form Coalesse in 2008. Coalesse products are meant for what the company calls "live/work” spaces, a result of the frequent overlap of home and office in modern working habits. In 1985, Steelcase purchased the Meyer May House designed by Frank Lloyd Wright and restored it, opening it to the public in 1987. A corporate art program has resulted in a collection including pieces by Pablo Picasso, Andy Warhol and Dale Chihuly. The company employs a research group called WorkSpace Futures to study workplace trends. In 2010, Steelcase underwent a three-year project to update its Grand Rapids headquarters to promote employee productivity and employee well-being, including redesigning a cafeteria into an all-purpose work environment that provides food service and space for meetings, socializing, and independent work.
