Since 1926, Spring Air has been widely recognized for its innovative mattresses and sleep sets. Francis Karr, who founded the company, was himself a true visionary. His groundbreaking free-end offset coil design, which adapts to each sleeper’s weight and body contour, is now the most widely copied design in the bedding industry. In the late 1940s, the company introduced button-free technology, quilted surfaces, and extra-supportive bedding materials, setting new standards in comfort. By 1953, Spring Air had launched its revolutionary “Health Center” mattress, featuring specialized zones to provide enhanced support for different areas of the body.
