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 Beautyrest brand in the lyrics of his 1934 song "Anything Goes".
