What is this temperature-sensitive thing that they talk about with Memory ™ foam?
A very interesting question with numerous answers! This is because the formulas used by foam producers to make viscous elastic foams vary from country to country, from climate to climate (the air temperature in the factory when it is poured), and from chemist to chemist. You will not get two viscous elastic foams performing the same in respect to their softening properties when placed next to the warm human form. Depending on the formula used, the foam may be quite ‘hard’ in its natural foam, and then when you sleep on it will soften to some degree. Some soften more than others when in contact with body heat. Some are fairly soft to start with even before being exposed to the body’s warm or the environment. There is simply no benchmark! But most viscous elastic foams will react (soften) when exposed to your body’s warmth. Heat sensitive in other words. And this allows the foam to mould to your shape, which is usually advantageous in respect to balanced support. The key to optimum balan
