Description

MATTRESS WITH CLIMATE CONTROL FUNCTIONALITIES
FIELD OF INVENTION
The invention relates to a mattress. More specifically, the invention relates to a mattress configured to provide climate control functionalities.
BACKGROUND
Mattresses commonly found nowadays usually comprise one or more cushioned regions, wherein the cushioning effect of each region may be achieved by different technical means utilizing different materials. Such means and materials comprise foam-like natural and synthetic materials, coils, springs and/ or a combination thereof. Most of the focus has been expended on developing the mattress with regard to correct and healthy sleeping positions of the human body. However, although the sleeping climate provided with regard to temperature and air humidity within a mattress as well as surrounding a user sleeping on the mattress plays a vital role in achieving healthy sleep conditions, the sleeping climate provided by a mattress has so far been overlooked as an important factor of sleep quality.
Therefore, there is a need for a mattress that may provide a user sleeping on the mattress with a comfortable and healthy sleeping climate.
