Kiturami unveiled a third-generation carbon mat under the banner of "the science of sound sleep." Unlike a hot-water mat that heats water and circulates it, a carbon mat converts electricity directly into heat using carbon heating elements. As Korea's sleep market has grown to 3 trillion won, Kiturami shifted its strategy to pursue sound sleep and energy efficiency based on temperature control technology.
According to the industry on the 30th, Kiturami developed a carbon mat that improves sleep quality by automatically adjusting its temperature in response to changes in body temperature. Heat spreads evenly and temperature control is fast. Because it does not require water, there is no risk of leakage or bacterial growth.
Sleep is divided into three stages—falling asleep, deep sleep, and waking—and the temperature can be set differently for each stage. When a user inputs sleep time, the temperature is lowered at the beginning to prevent a rise in body temperature, then maintained at a constant level for deep sleep. Two hours before waking, the temperature is raised again to help the body wake naturally.
A Kiturami official said, "The key to sound sleep is body temperature control, and automating it is the biggest differentiator of the carbon mat," adding, "We designed it to scientifically control temperature rhythms so users can get the same quality of sleep every day."
The product's heat source is a carbon heating element based on aramid fiber. Durability was reinforced by double-coating aramid fiber, which has high strength and heat resistance. It also passed 800,000 bending tests. It is certified for electromagnetic field (EMF) safety to minimize electromagnetic effects, and heat is quickly delivered and evenly dispersed to keep body temperature steady. With no motor, operating noise is low.
It also improves the feel when lying down by enhancing thickness and elasticity. It passed both washing machine wash tests and children's textile product safety tests.
Energy efficiency is also high. Power consumption is 160 watts, cutting electricity use by about half compared with conventional hot-water mats. Based on eight hours of use per day, the monthly electricity bill is about 7,000 won.
Kiturami entered the heating mat market in 2011 by launching the industry's first hot-water mat. Starting in 2020, it shifted its business strategy to a "sound sleep-centered" approach and switched from hot-water mats to carbon heating-element mats. It is expanding a lineup focused on improving sleep quality while reducing issues with hot-water mats such as electromagnetic waves, leakage, bacteria, and noise.
A Kiturami official noted, "The third-generation carbon mat is not just a product that provides a warm bed, but a 'sound sleep technology platform' that scientifically controls body temperature," adding, "The heating industry will evolve around sound sleep going forward."
