Studies show sleeping in a hot environment makes it harder to drift off and reduces the amount of restful deep sleep you achieve.

Most mattresses can’t handle brutally hot Aussie summers. Our Intellicool technology™ keeps you cool in summer and gives you the perfect amount of warmth in winter — for a blissful nights sleep.
