KülKōte. Temperature regulating technology exclusive to Sleepyhead.
With New Zealand's coolest mattress
you’ll never be too hot in bed again
Your body temperature really affects how well you sleep. At Sleepyhead, our design team understand choosing the right mattress to suit your body temperature can be tough, especially if you’re sharing the bed with a partner who sleeps hotter or cooler than you. That’s why we’ve introduced KülKōte, our latest temperature regulating technology that senses whether you’re hot or cold and adjusts accordingly.
What is KülKōte?
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 maintained a temperature of 29°C. 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.
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.
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 bed 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.
What are the different types of KülKōte?
KülKōte is only found in Sleepyhead mattresses in New Zealand and we make them using different kinds of KülKōte for different beds. While they all use the same temperature sensing technology – we’ve supercharged it in some ranges by using elements like copper and silver.
KülKōte
KülKōte is a water based foam layer filled with wax microcapsules. Each microcapsule contains phase change material that melts to absorb heat when you get warm and hardens to release heat back when you get cool.
The benefit: A traditional mattress traps heat until the surface reaches 35°C, but KülKōte stops at 29°C so you stop waking up sweaty in the middle of the night.
KülKōte Copper
KülKōte Copper adds fine copper particles to the phase change microcapsules. Copper is one of nature's fastest thermal conductors, so it pulls heat away from your body more quickly while the microcapsules store and release energy as your temperature changes.
The benefit: Copper moves heat away fast enough to balance two different body temperatures in one bed, so hot sleepers cool down and cold sleepers warm up without fighting over the covers.
KülKōte Silver
KülKōte Silver combines phase change microcapsules with silver ions. Silver has been used for centuries as a natural antimicrobial. When your skin temperature rises above 29°C, silver pulls heat away. When you dip below 29°C, silver releases stored warmth back to you.
The benefit: Silver kills odour causing bacteria permanently so your mattress stays fresher for its entire life, giving you a cleaner and more hygienic place to sleep every night.
