|Since 1926, Spring Air has been widely recognized for its innovative mattresses and sleep sets. Francis Karr, who founded the company, was himself a visionary. His free-end offset coil design, which adjusts to each sleeper's weight, is now the most copied design in the bedding industry. Today, Spring Air distributes bedding internationally, with plants in the U.S., Canada, Mexico, Ireland, Australia, the Middle East, and Argentina. The company is the fourth-largest bedding manufacturer in the world and still leads the industry in product features and value.
