Serta Mattress is proud to be the number one mattress manufacturer in the United States and a leading manufacturer worldwide. In 1933, the manufacturers organized their companies under one name "Serta" and set national guidelines for the products they would make and market under that brand name. In creating its flagship mattress, the Perfect Sleeper, the entrepreneurs struck a powerful balance. They developed a nationally recognized brand as well as a network of local companies dedicated to growing their retail partners’ businesses. Serta is proud to be the manufacturer of the World’s Best Mattress!
