Memory foam, also known as visco-elastic, was originally developed in conjunction with the NASA space program to protect astronauts from the harmful effects of G-forces. Memory foam has the unique ability to conform to an individual’s body shape in order to provide support where it is most needed. This reduces the need to toss and turn in order to find a comfortable position. Because it puts less pressure on your body you will benefit from improved circulation, reduced stress and enjoy a truly relaxing night’s sleep.
