Invented in 1870 by an American named Zalmon G. Simmons, the pocket spring mattress consists of barrel-shaped springs introduced individually into a pocket of non-woven material.
Each mattress therefore consists of several hundred springs that are independent of each other. On this layer of springs, various garnishings can be placed: Bultex®, latex or visco elastic foam.
The quality of a spring mattress depends on the various additional stuffings, synthetic, wool, cashmere or natural silk for the most sophisticated.
