One of the most common complaints when you’re in bed is that feeling of being too hot. When you jump into bed, you’re like a human water bottle, and you quickly start to heat up the foam layers below.
This results in throwing off covers, sticking out a foot to cool down, or just general unrest while trying to sleep. However, your partner might suffer the exact opposite and feel cold in bed.
KulKote Temperature Regulating Technology
“The technology’s been around for a while, but no one’s really thought to put it in a mattress before,” says Sleepyhead owner Graeme Turner. So how does it work? Inside KulKote are tiny microcapsules which, once you’re lying on the mattress, heat up and liquefy inside the layer and start the process of absorbing heat. Which might make the bed feel cooling.
“The advantage of it is that we put a coating of the KulKote on the foam, so when you’re lying on the bed there’s actually a coolness to the bed and it moves the heat away from your body,” says Graeme.
However, KulKote cleverly doesn’t take away all your heat. It senses what’s needed to keep the bed cool or warm according to your body temperature.
How to keep cool in bed?
Here’s the simple science behind KulKote in your mattress. When your skin temperature reaches between 29°C and 33°C, the KulKote technology activates. Auckland University testing found that in a simulation of someone asleep on the KulKote mattress, the sleep surface reached 29°C and stayed at this temperature for 22 straight hours. Now that is a cool bed!
But, on a traditional mattress without KulKote, the sleep surface reached 35°C and stayed that way – a full six degrees hotter. A hot mattress is not ideal to sleep in unless you’re a hot sleeper.
It’s similar technology to what’s used in spacesuits to regulate the body temperature of an astronaut. Bringing this innovation back to Earth and into your sleep has become an integral part of the Sleepyhead product design team. Graeme Turner is adamant it will “revolutionize the way beds are made in the future”.
His product design team has worked with KulKote to advance the innovation further by integrating copper into the technology to boost its benefits.
“Kulkote has really been a game changer for us in the way we look at how people sleep.”

Combining copper and KulKote together supercharges the temperature regulation, as copper is one of Mother Nature’s best- known thermal conductors. Sleepyhead’s Group Product Development Manager Dean Rope says: “KulKote has really been a game changer for us in the way we look at how people sleep.
“We see a lot of innovative opportunities for the future around bed manufacturing as we constantly try to perfect what a great night’s sleep looks like,” he says.
Hot and cold mattress
A common question in the bed business is whether you sleep hot or cold. It’s interesting to note that women as a general rule sleep colder than men. This can be put down to your metabolic rate. Women have a lower metabolic rate so they produce less heat than men and this can make them feel colder in bed.
Men typically have more muscle mass and generate more heat, so that might explain why there may be a lot of disparity – not to mention duvet hogging – between men and women in bed. KulKote goes some way to help through its amazing temperature regulating technology. It’s now available exclusively for commercial applications in Sleepyhead Sanctuary beds. Try it and feel it yourself, these are some ways that you could stay cool at night in bed if you’re feeling hot.
