Among the biggest complaints people have contrary to their cold foam mattress (kaltschaummatratze) is that it becomes too hot. However, not all of beds are made equal. Because the subtle differences in chemical makeup, some foam beds remain cooler than many others.
The most important reason that foam mattresses may get hot is that they’re made to set your body in as close touch as possible with all the foam. Foam works optimally when you’re in contact with it. The more layers you have between you and the foam, the less powerful the foam will be. However memory foam is also a good insulator, so becoming nearer generates a much better texture however, also means the sleep experience will probably be a bit warmer.
Innerspring beds, and lots of all bunk beds, have a coating of polyester fiber only under the ticking and over the foam. This coating of filling forms a thin barrier between you and the memory foam, and does a superb job of distributing the heat from the human body. However, most memory foam beds don’t have a fiber coating. Their cotton cap is located right along with this memory foam. So it is left entirely up into the foam to distribute heat from the human body.
kaltschaummatratze is a open cell structure substance, meaning that its cell walls are available. The open cell structure allows foam to fall to consume body weight and enlarge to give support. In addition, it allows heat to flow from the body as you sleep. And this is what that makes a foam mattress sexy or not. How does the memory foam on your mattress disperse heat? Different mattress manufacturers use different memory foam, therefore the only way to actually understand whether a mattress is going to be too hot for you will be to sleep on it.
