Memory foam reacts in a variety of ways depending on how much pressure or “force” you apply to it. It is important to note that if you apply pressure rapidly, the foam will change form more slowly, or “reluctantly.” This implies that memory foam is great at absorbing the force of an impact, which is why it was initially employed in areas like as space shuttle construction. It is this characteristic of memory foam that allows it to be utilised as a mattress material since it enables the mattress to cushion the body uniformly and provides the gradual contouring sensation as the mattress adjusts to the pressure of your weight and re-forms around the contours.
When stress is removed from memory foam, it returns to its original form only slowly–on average, it takes 5-10 seconds to back to it’s original shape. During this time of recuperation, the energy received and lost by the collision is re-channeled. This temporal lag, which is caused by a process known as “hysteresis,” also serves to cushion sleepers by removing part of the stress (or impact energy) generated by the prone bodies as they fall asleep.
For the reasons stated above, memory foam beds are intended to gradually adapt themselves to the body in reaction to pressure, and as a result, to divide up the user’s body weight. The materials are also intended to be robust, and to restore to their original form once the body’s weight and pressure are lifted off of them. There are mattresses available that meet the criteria for all three of the most common kinds of memory foam, as well as mattresses that integrate copper into their composition.
There are three major features define memory foam mattresses as a whole, but various mattresses will provide variable degrees of each of these traits.
Contouring: One of the defining features of foam mattresses is pretty simple to understand. When you lay down on a memory foam mattress, you can sense the sleep surface mould precisely to the contours and angles of your body.
Sink: In contrast to contour, memory foam seems to have a “sink” to it–that is, the sensation of being hugged by the bed, and even of sinking down into it.
Palpable Reaction: As stated above, memory foam is highly adaptable to pressure, and you can feel the material become more flexible and less viscous in response to those forces and heat of your body as you lay down.
