1875, Mr. Simmons read the news in the newspaper about making springs with hand-woven steel wires and came up with the idea of making mattresses with springs. Although the asking price of a spring at that time was $65,438 +02, which was equivalent to two days' wages of workers, Mr. Simmons and nine skilled craftsmen used the principle of spring force and reaction force. The following year, 1876, 14 springs were used to manufacture the world's first spring mattress, rewriting the history of mattresses and human sleeping habits, and starting the legend of Simmons with a glorious century. A story of lying in Simmons' bed and feeling well asleep began to leave traces in historical stories and literary masterpieces all over the world. Zalmont Gilbert Simmons was later addressed as "Simmons".

After 1876 created the world's first spring bed, Mr. Simmons later established the brand of spring bed in his own name-Simmons Simmons, and Simmons began to become synonymous with advanced spring mattresses. In China national language dictionary, Simmons is the general name of western-style spring bed, but in Chinese mainland, there is not even a name for spring bed, which is directly called Simmons Simmons.
