Spring Air Company Spring Air Company is a mattress company based in the United States. It was founded in Chicago in 1926 when Francis Karr patented a mattress design with free-end coils. Because of the heavy weight, high transportation costs, and low value per unit weight of mattresses, they are often manufactured locally. The company is thus a licensing organization, with local licensees manufacturing the mattresses under a common name for national marketing. Like a cooperative, the licensees own the Spring Air name. Spring Air has factories across the world.
