The heart of this bed is made from revolutionary SmartCell. Aussie ingenuity at its finest, SmartCell uses clever chemistry to minimise VOCs and create a uniform bubble structure that’s more supportive, more comfortable, and more breathable for a cooler, drier, more comfortable night's sleep. SleepMaker Elements mattresses have been designed specifically to be easy and efficient to recycle, helping great projects like the Soft Landing keep more old and unwanted mattresses from landfill.
