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.

Product Philosophy and Commitment

Sealy is dedicated to helping the world sleep better. With over a century of experience, Sealy mattresses are designed to deliver the perfect blend of comfort and support at a great value.

Sealy is committed to sustainability and environmental stewardship. It uses environmentally friendly materials and processes wherever possible and strives to minimize its environmental footprint through waste reduction and energy efficiency initiatives. The company also places a high priority on ethical business practices and community involvement, contributing to various social causes to improve the quality of life in the communities where it operates.

Whether you're looking for cutting-edge technology in a mattress or the dependable comfort of a traditional innerspring, Sealy offers a variety of products to help you find the perfect night's sleep.
