The Hoffman Estates, Illinois-based Serta is an American business that specializes in creating and producing mattresses. 13 mattress manufacturers who had obtained licenses to use the Serta name created Sleeper, Inc. in Illinois in 1931; eight separate licensees who later operated as a cooperative owned the business. After that, its largest licensee, National Bedding Company, took control of it and began running it as Serta International (which ultimately held 27 of the 34 U.S. Serta manufacturing licenses).

The American business Serta International is a division of Doraville, Georgia-based Serta Simmons Bedding, LLC. Serta Dormae in Texas, Serta Restokraft in Michigan, and Salt Lake Mattress in Utah are a few additional licensees.
