A method of making a curved compression spring comprising the steps of: providing a monolithic preform having first and second end portions with a curved mid-portion therebetween, with the preform being formed from an elastomer which is free of spring-like characteristics, and with the preform having an initial predetermined length defined by a longitudinal distance between first and second end portions, and wherein the elastomer from which the preform is formed has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1; and, working the preform so as to orient the molecular structure of the elastomer in at least one direction while transmuting the preform into a compression spring.
