What unexpected source led to the development of memory foam?

Answer

NASA for spacecraft cushion safety

Memory foam originated from research conducted by the National Aeronautics and Space Administration (NASA). This material was initially developed during the 1960s with the specific purpose of enhancing the safety and cushioning capabilities within spacecraft. Although it was designed for the rigorous demands of space travel, the material was later adapted for commercial use, transitioning into mainstream mattresses during the 1990s due to its unique visco-elastic properties that allow it to mold precisely to the contours of the human body, thereby offering exceptional pressure relief.
