My New Novosbed Mattress: My experience versus Tempurpedic

[MFC]

Hi Phoenix,
Thank you for the links!
I was trying to understand, how these air flow technologies inside the mattress, are supposed to keep cool you while you are lying on top of the mattress.

Other manufacturers are using various combinations of holes punched in their memory foam or different types of airflow channels in the memory foam or the polyfoam underneath it to encourage airflow. These are often less effective than more open celled foam … although this can depend on whether these airflow channels actually stay “open” and allow airflow from the body surface to the outside environment during actual use.

Now I understand!
