Sealy. History. Heritage. And an undying dedication to helping the world sleep better. Sealy Middle East Licensee of Sealy Inc. USA is proud to present the number one mattress in the world in the Middle East Region. Lie on any Sealy mattress and you channel a century and a quarter of mattress ingenuity. A journey that began 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.
