In 2012 Sealy was acquired by Tempur-Pedic International. Sealy sells the majority of its mattresses under these main brands: Sealy® Brand, Sealy Posturepedic®, Stearns & Foster®, Optimum™ and Bassett®.

Sealy was founded in 1881 in the town of Sealy, Texas, when Daniel Haynes, cotton gin builder, filled a request for a cotton-filled mattress. And then another. And then another. His business grew exponentially, which led to more innovations and several patents. Among them, a machine that compressed cotton. Milestones include the introduction of the Sealy Posturepedic mattress. Being the first mattress company to display and advertise a king-sized bed. Creating an Orthopedic Advisory Board. Reinventing the innerspring coil and the box spring. In late 1983, Sealy purchased the Stearns & Foster Company. True to the Sealy heritage, these mattresses redefined luxury and expressed a dedication to craftsmanship and intricate detail. Making it a perfect and sound addition to the Sealy family of beds.

Sealy's corporate headquarters are located in Trinity, NC. Today the company owns and operates 25 bedding plants in the U.S. In September, 2012, Tempur-Pedic International announced an agreement to purchase Sealy. On March 1st, 2014 Tempur Sealy International changed warranty terms for all premium products from 25 year limited warranty to 10 year non-prorated.
