I FOUR FEATURES/ADVANTAGES  OF COOL AND WARM MATTRESS 
1,sleep cool and sleep warm
Cool and warm mattress  , to use advanced semiconductor technology, temperature from 18 °C - 48 °C, free adjustment, and achieve the effect of cooling and warming for sleeper.
 
Small heating and cooling area and quickly to get heating or cooling, what’s more can keep a constant temperature, make human body have more healthy sleep.
 
2, Water temperature control, Environmental-friendly
Air conditioner mattress just need to re-fill water in certain period, it do not produce freon and have no Air conditioning compressor, more environmental-friendly comparing to regular air conditioner.
 
3,Water temperature control, safe and low electric cost
Just some water is circulating inside of mattress, through the semiconductor to reach heating or cooling, so have No power No radiation, can open the window and sleep under natural ventilation environment. Low electric cost, just need 10 hours/1kwh.
 
4,Healthcare
Principle of healthcare:
 
The magnetizing system of the machine can magnetize cyclic liquid that inside of the mattress constantly, for that, can produce magnetic field effect. The effect promote human blood circulation, eliminate fatigue, still can solve the papula and eczema on the back of people who lie a long time on beds or who can not self-care patients, and other discomfort troubling.
 
II  PK with  Electric blanket ,Air conditioner and Electric fan
 1,Electric blanket
Weak point: no safe, have radiation, will suffer eczema and skin itch ,chest distress swirl…
 
Numerous studies point out the possible health hazards for low-frequency electromagnetic fields which electrical blanket produce, and electrical blanket is a risk to leak electricity, besides the temperature is not easily to be controlled.
 
 2,Air conditioner
Weak point: high power consumption, high electric cost, no environment-friendly no energy conservation. Air can not circulate, it is humid and easy to get the cold, also will suffer headaches, limb weakness, and muscles pain, etc
 
 3,Fan
Weak point: having noise, cooling effect is not apparent, and only by one-way use, long time to use fan will cause headaches, limb fatigue etc.
