A video is going viral on social media, in which the entire process of making black foam used in sofas and mattresses is shown in detail. It is extremely interesting to see how this foam is transformed from a chemical mixture into a huge block and then cut into different shapes. This factory tour video shows how chemical substances like polyurethane are mixed to form a large foam block, which is then dried and cut to the desired thickness and shape with the help of huge machines. During this process, the mixture flowing on a giant conveyor belt rapidly expands and solidifies, creating a giant ‘roll’ of foam.
