Chilisleep ooler sleep system / heating & cooling for bed

This is a system that will circulate cooled (or heated, for winter) water over your mattress. Removes the need for AC and gives you a better, deeper sleep. The mat itself is approx. 200 cm x 150 cm ("king" size) but fits beds of up to 180cm in width (it's elastic and has a wide margin). The mattress should not be higher than ~30 cm. It comes with two cooling units that can be controlled separately, e.g., for couples that prefer different temperatures. Used in perfect operating condition. The mat has been cleaned professionally. I imported this from the US, as the system was not available in Europe. New price was $1,899.
