The visco memory foam used in all Sleep Science mattresses is exclusively manufactured in South Bay International’s company-owned facilities overseas. South Bay International is an American company with ownership in its own visco memory foam factory in Xia Jing, China.

South Bay International had purchased foam in the past, but found it imperative to the future success of our
business that we ensure the quality of our product. Therefore, we built our own foam factory and we staff it with quality control personnel whom have put strict controls in place to ensure the highest quality visco-memory foam is produced. Our product is also tested on regular intervals by a third party testing laboratory.

700,000 square foot state of the art, fully integrated factory includes…

• Proprietary foam recipes
• All polyurethane and visco foams manufactured on site with modern technology and equipment.
• All mattress core assembly and bonding done on site.
• Rigorous quality control procedures.
• Mattresses are pressure rolled and packaged on site to enable greater product quantity per container, helping to reduce the overall landed cost of the product.
Research and development is a cooperative effort between our U.S. and Chinese teams
