The mattress was developed to be able to meet with the bed shoppers' demand.The annals of the Memory Foam Mattress can be traced back to NASA's Ames Research Center. NASA's Ames Research Center funded a project to style a mattress foam that will help to ease pain of the astronauts caused by g-forces back inside the 1970s.
