KulKote Temperature Regulating Technology

Sleep makes life better. But who makes sleep better? SleepMaker – The people who’ve been making mattresses for How we sleep, coupled with the room temperature or if you share a bed can all affect our body temperature at night. Women have a lower metabolic rate than men so they produce less heat and can sometimes feel colder. But every one of us is different, so choosing a bed to fit can be difficult. So, we’ve introduced a unique technology Kulkote into our mattresses that senses how you sleep, hot or cold.

What is Kulkote?

University tested

Kulkote 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 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. However, on a traditional mattress without Kulkote, the sleep surface reached 35°C and stayed that way – a full six degrees hotter than the mattress using Kulkote.
