The use of the blowing agent in the inner material produces a repeatable and consistent structure, as the blowing agent is uniformly activated through the product. The use of the gas-assist the heat and pressure associated with the blowing agent is allowed to out gas, thereby insuring that the finished molded chair or other item is aesthetically pleasing while providing increased strength and reduced weight compared to traditional plastic chairs formed with known methods.
