within the next 24 hours from one of Simmons' 64 warehouses. This arrangement reduced the need for retailers to own and store their own product inventories. In 1923, Simmons moved its corporate headquarters to New York City. Equipment developed by Simmons in 1925 automated the process of coiling wire and inserting it into fabric sleeves, called encasements. This allowed mass production of pocketed coils, a type of coil that had been available only in very high-priced luxury mattresses. The pocketed coil is the basis for the Simmons Beautyrest mattress brand, which was introduced in 1925. Although the new manufacturing technology greatly reduced its cost, at the time of its introduction a Beautyrest mattress sold for $39.50, three to four times more than the typical price for a standard wire mattress. Simmons promoted its products aggressively with ads that included testimonials from famous people such as Eleanor Roosevelt in 1927 and Henry Ford, H.G. Wells, Thomas Edison, Guglielmo Marconi and George Bernard Shaw in 1929. Eleanor Roosevelt continued to promote the brand into the 1930s, through her radio show. Cole Porter mentioned the Simmons brand in the lyrics of his 1934 song "Anything Goes". In 1940, Simmons introduced the Hide-A-Bed, a sofa that incorporates a fold-out spring and mattress that pull out to form a bed. This became one of the company's best known products and was manufactured until the 1980s. During World War II, Simmons' facilities were diverted to military production, making cots, parachutes, bazooka rockets and other products. By the post-war year of 1947, the company was back in the mattress business and started using advertising to associate its products with the Hollywood glamor of actresses including Dorothy Lamour and Maureen O'Hara. A research and development facility was established in Munster, Indiana, in 1957, building upon pioneering studies on human sleep behavior that Simmons had sponsored in the 1930s. In 1958, the company became the first U.S. mattress maker to produce mattresses in king and queen sizes, an innovation that was promoted as solving the "space battle in the bedroom". Era of corporate change In 1975, the Simmons corporate headquarters moved to Atlanta, Georgia. Shortly thereafter, the company research and development team also relocated to Georgia, to a building in what is today Peachtree Corners. In 1995, the company's R&D division moved into a new home, the Simmons Institute for Technology and Education (SITE). Simmons underwent the first in
