Discover Australia's coolest temperature regulating technology.


Sleep Hot or Not?

Your body temperature really affects how well you sleep. That's why we've introduced KülKōte, the latest temperature regulating technology that senses whether you're hot or cold and adjusts accordingly.

How does KülKōte work?

KülKōte technology is similar to what’s used in spacesuits to regulate the body temperature of an astronaut. When your skin temperature reaches between 29°C and 33°C, the KülKōte technology activates. Auckland University testing found that in a simulation of someone asleep on the KülKōte mattress, the sleep surface reached 29°C and stayed at this temperature for 22 straight hours. However, on a traditional mattress without KülKōte, the sleep surface reached 35°C and stayed that way – a full six degrees hotter than the mattress using KülKōte.

How does your body temperature affect sleep?

I sleep hot

You may have gone to bed feeling fine but wake up too hot or with night sweats. Struggling to find a cool patch on your mattress or peeling back the covers means sleep can feel elusive.

How it works: KülKōte is designed to absorb that heat so the mattress stays at an even temperature, helping to stop you waking up feeling too hot.

I sleep cold

Just because KülKōte can feel cool to the touch, doesn’t mean it will make you feel colder in bed. The technology works on sensing your body temperature and stores energy, ready to release it when you’re too cold.

How it works: If your temperature drops, the KülKōte layer will release any stored energy back to the sleep surface.

The Magic of KülKōte

Too hot in bed? KülKōte absorbs heat energy and a cooling effect is created. As the heat source is removed, the energy stored within KülKōte is released. If you get too cold in bed, this stored energy pushes back while you sleep, helping to manage your temperature and keep you more comfortable in bed.

Frequently Asked Questions

Who invented KülKōte?
SleepMaker found KülKōte, a US-based technology while developing a temperature regulation mattress few years ago. Pronounced 'cool coat', this technology wasn't originally created with mattress temperature regulation in mind. It was used on a variety of materials, fabrics, foams, and textiles to aid in cooling. Our product team came upon the concept and believed it may be useful in the development of a cooling mattress.
How do you put KülKōte into a bed?
A layer of KülKōte technology is rolled on to the top foam layer of your new mattress. With exclusive temperature reactive microcapsules, the technology is incorporated in our Australian made foam. To develop a surface infusion that collects and releases heat energy at precise degrees for a more consistent and pleasant sleep, a novel water-based polymer is combined with temperature reactive microcapsules.
I get hot in bed, but my partner sleeps cold. Do we buy the same mattress?
Yes, KülKōte's beauty lies in its ability to react to individual body temperatures. It's a mattress designed for couples who have varying body temperatures. Sensory technology is used. Once you're in bed and your body starts warming up the sleep surface, the microcapsules inside the layer of KülKōte go to work. In a temperature-regulating mattress, if you're too hot, the Kulkote absorbs it, but if you're too cold, it releases it. It means you and your partner may each sleep in your own unique manner.
Does body temperature vary between men & women?
Both men and women have a body temperature of roughly 37 degrees celsius but due to men typically having a higher percentage of muscle mass than women, men generally generate more heat. Because women have lower musscle mass, they have a lower metabolic rate and feel cooler in bed. However, besides muscles, there are
Is there any proof KülKōte works?
New Zealand's Auckland University has put our KülKōte technology to the test. In a bed with the new innovation and another mattress without KülKōte, skin temperatures were observed for nearly 24 hours. The KülKōte technology activates when your skin temperature hits 29°C to 33°C. In a simulation of a person sleeping on the KülKōte mattress, the sleep surface reached 29°C and remained at that temperature for 22 hours. The sleep surface on a typical mattress without KülKōte, on the other hand, reached 35°C and stayed there.
