That spring in your step after a good night's sleep may be there courtesy of Leggett & Platt (L&P) -- the pioneer of steel coil bedsprings.

It also makes commercial fixtures (shelves and work furniture). Customers include furniture retailers, telecommunications firms, and makers of automobiles, construction products, bedding, and lawn gear. L&P operates about 130 manufacturing facilities in 18 countries.
