This mattress uses a water circulation system rather than electric heating wires or air conditioning. A compact unit gently circulates temperature-controlled water through a hidden network of soft internal tubes inside the mattress. Because water transfers heat evenly and smoothly, the mattress surface warms or cools consistently from edge to edge — with no hot spots, no cold spots and no noisy compressor. You simply set your desired temperature on the control unit, and the water system maintains it throughout the night.
