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.
Spring Air has earned a reputation over the years for continuous product improvement. In the late 1940s, the company introduced button-free technology, quilted surfaces and extra-supportive bedding materials. In 1953, Spring Air began producing its Health Center mattress, which featured zones for different areas of the body. The company began manufacturing the Back Supporter mattress in the early 1960s, and sales doubled within seven years.
Among other enhancements to Spring Air mattresses were the pillow top mattress (1973), natural fiber bedding materials such as silk and wool (the Four Seasons concept in 1988), and Conforma foam which conforms to your neck, shoulders, and lower back (1991). Innovation continued into the 1990s with the introduction of latex/innerspring combination products. In 1995, Spring Air introduced a product line that uses three zones in the foundation for durability, zoning in the innerspring for support, and seven zones in the Conforma Foam for total sleep fitness.
In 1999, Spring Air introduced the ultra-premium Back Supporter Comfort Caress Collection... Better Comfort, Better Quality, Better Value. In 2000 Spring Air introduced "The latest sensation in sleep innovation." The foam encased perimeter design, Foam Encased Wireless Edge, provides more support, more comfort, and more edge-to-edge sleeping surface.
