Kulkote Beds

Too hot or too cold? How we sleep, coupled with the room temperature or if you share a bed, can all affect our body temperature at night. Every one of us is different, so choosing a bed to fit can be difficult. Sleepyhead has introduced a unique technology called Kulkote into these mattresses that sense how you sleep, hot or cold.
