Why memory foam?
Memory foam was originally developed for NASA space flights as a way to relieve the pressure of extreme g-force that astronauts experienced. Due to the benefits that the memory foam possessed, they were introduced to the consumer retail market. The main selling point of memory foam mattresses is their temperature sensitivity. The ability to respond to body heat allows the mattress to shape to the curves of the body. What this ultimately means is proper alignment of the spine during sleep and relief on pressure points. There are three main factors that influence the feel of memory mattresses; firmness, thickness and density of the foam layer.
