Though our ancestors may have slept on leaf, straw, feather, or even horsehair mattresses, modern technology offers the foam mattresses as an option to the more contemporary cotton mattress with coil springs. But, how did we ever get to using foam as a bedding material?
The foam used in modern mattresses and many packaging and insulating materials is polyurethane foam, a discovery of German scientist Otto Bayer in 1937. Although Mr Bayer has no family association with the Bayer Group, he joined their research team in 1934, and later pioneered polyurethane chemistry and continued to develop that and other chemical technologies with for many years.
In time, researchers William Hanford and Donald Holmes teamed up at the Labs of E I du Pont in the United States, and created a multipurpose polyurethane manufacturing process that was patented in 1942. Their process continues to be used in the manufacturing industry to this day, though significant advances in both polyurethane chemistry and manufacturing have refined both the process and the resultant products.
In the 1970s, NASA researchers at the Ames Research Center in California, searching for cushioning materials that would help astronauts deal with the massive g-forces and other concerns of space flight, discovered a […]
