For flexible foam molding, dispensing machines are used to vary the output of chemicals or the component ratios during the pour. This allows the production of molded foams with dual hardness. Molded foam articles with solid surface skin are made from liquid chemicals in a single step, using carbon dioxide as the sole blowing agent. Automotive cushions are made by molding flexible foam behind a pre-shaped fabric cover. This process reduces the number of steps in the manufacture of car seats. In addition to monitoring the production process, the final product is inspected and tested for various physical and mechanical properties. An important property of foam rubber is called the indentation load deflection, which measures the spring tension or load-bearing quality of the material. The deflection is determined by the amount of weight needed to compress a circle of foam 50 sq in x 4 in (127 sq cm x 10.16 cm) thick by 25%. Most seat cushion foam has a rating of 35, which means it takes 35 lb (15.9 kg) of pressure to compress the circle of foam 1 in (2.54 cm).

Originally, foam rubber was made from natural latex, a white sap produced from rubber trees. As early as 500 B.C. , Mayans and Aztecs used this latex for waterproofing purposes and also heated it to make toy balls. During the early 1900s, the first patent for synthetic rubber was granted and several decades later a process for foaming latex was invented. Another process was developed in 1937 for making foams from isocyanate-based materials. After World War II, styrene-butadiene rubber replaced the natural foam. Today, polyurethane is the most commonly used material for foam products. Foamed polyurethanes currently make up 90% by weight of the total market for polyurethanes.
