Sealy manufactures most bedding to order and has adopted "just in time" production techniques in its manufacturing process to more efficiently serve its dealers' and customers' needs. Most bedding orders are scheduled, produced and shipped to retail warehouses within 7 days of receipt. This rapid delivery capability allows Sealy to better satisfy customer demand for prompt shipments. Sealy operates 25 plants, which manufacture bedding in 20 states, three Canadian provinces, Mexico, Puerto Rico, Brazil, Argentina, France, and Italy. Sealy operates a research and development center in High Point, North Carolina, with a staff that tests new materials and machinery, trains personnel, compares the quality of Sealy's products with those of its competitors and develops new products and processes.
Products sold in Canada are made in Canada and to ensure quality of raw materials and labour practices, Sealy sources most of its components from local supply. Sealy does not manufacture in off-shore facilities.
