In a 30,000-square-foot facility in Carthage, Missouri, more than 40 engineers are building the future of the bedding industry. Leggett & Platt’s IDEA Center, which stands for Innovation, Design, Engineering, and Acceleration, is a state-of-the-art complex with a research library, electrical and mechanical engineering labs, testing facility, and product showroom. Under one roof, our team collaborates to develop bedding and sleep products that keep our customers at the bleeding edge of innovation. It started in 1885 when J.P. Leggett patented the first spiral steel coil bedspring. More than 600 patents later, we are still working to bring the best ideas to the bedding industry.
