Sealy Mattress Company: Overview and History

Founded in 1881 in Sealy, Texas, Sealy Mattress Company has grown from a small, one-man operation to one of the largest mattress brands in the world. The company began when Daniel Haynes, a cotton gin builder, started making cotton-filled mattresses for his friends. Over time, his innovation and craftsmanship led to the development of the first mattresses made with compressed cotton, setting a new standard in comfort.

In 1950, Sealy took comfort to the next level with the introduction of the Posturepedic mattress, designed in cooperation with orthopedic surgeons to ensure a night's sleep that was both supportive and comfortable. This innovation cemented Sealy’s reputation as a leader in mattress technology.

Today, Sealy continues to innovate, combining science with quality craftsmanship. The company's commitment to comfort, support, and quality is evident in its wide range of mattresses that cater to various preferences and sleep styles.
