The mattress was created in order to meet up with the requirement of the mattress shoppers. The Polyurethane Foam Mattress' history can be traced back again to NASA's Ames Research Center. NASA's Ames Research Center borrowed a project to design a mattress foam which will help to ease back pain of the astronauts caused by g forces within the 1970s. NASA assumed that the foam product must be applied to adapt to the shape of the body. The person would ultimately move-out of the career although creating a shape for the body will help resolve the situation. Because of this, wrong pressure points will be formed on the body.
