Cosco Juvenile specializes in baby products ranging from car seats to strollers. In 1974 Cosco Juvenile was introduced to the world with its first product the Two Step step stool. Since then, they've gone on to win nation-wide recognition and several awards for providing innovative, quality car seats. In 1998, Cosco debuted the High Back Booster child seat which became number 1 on the US market in less than a year. Since 1935 Cosco has maintained the same high level of quality car seats that consumers of juvenile products have come to expect.
