The Chilibed from Chili Technology has a mattress that allows for a temperature controlled bed. With a touch of a button, either side of the mattress can be heated up or cooled down.
This temperature controlled bed is filled with water. A unique integrated system allows for heat adjustment between 48 to 118 degree Fahrenheit (9-48 degrees Celsius). Aside from providing bedtime comfort, the Chilibed is also eco-friendly as it is made from 100% soy.
Interesting fact: The person responsible for the Chilibed is actually the nephew of the man who invented the traditional water bed.
