Polyurethane foam was discovered by Otto Bayer in 1935. In recent years the evolution of manufacturing technologies has enabled the creation of ecological forms of expanded polyurethane. The latest generation of polyurethane foams are very resilient (returning to their original form when pressure is removed), elastic and are free from toxic substances.
Open pored foams which are realised using water and prime mate rials which do not damage the environment. The open-celled structure is similar to natural sponge; hygienic, porous and able to disperse heat and humidity.
