For helical springs, wind some wire of the correct alloy into shape. For some uses this is all that is needed but for more demanding uses, the metal then has to be heat-treated to change the crystal structure in the steel - changing the structure alters various physical properties of the steel so that you finish with a suitable spring. Other types of spring are made from flat steel plate - such as leaf springs, they aren't wound, but the principles are otherwise the same.

Yes, a shiny substance such as steel wire is commonly used to make flexible bed springs. The steel wire is treated to give it its shiny appearance and to ensure durability and flexibility in the springs.
