[E-Daily Reporter Kim Se-yeon ] Kyungdong Navien ( KYUNGDONGNAVIEN(009450)), a leading domestic boiler manufacturer, announced on the 9th that it ranked first in the heated mattress category for the 11th consecutive year and took first place for the first time in the kitchen range hood category in the “2026 Premium Brand Index” (KS-PBI). The company is distinguishing itself in various business sectors related to daily life, extending beyond boilers.

The Premium Brand Index, jointly developed by the Korean Standards Association and the Seoul National University Business Research Institute, surveys brand value as perceived by consumers. The evaluation process comprehensively assesses future value, including social responsibility.
The “Navien Sleep Mattress,” which has been ranked No. 1 in the heated mattress category for 11 consecutive years, is KYUNGDONGNAVIEN’s flagship product. It was the first in the heated mattress industry to receive “Good Sleep Gold Mark” certification and features precise temperature control technology in 0.5-degree increments. The company also offers a diverse product lineup, including the “Deep Sleep Mat Hot Water” for consumers seeking a cozy, warm sensation and the “Deep Sleep Mat Carbon” for convenient usability.
In particular, the Deep Sleep Mattress (Hot Water) maintains a consistent temperature set by the user throughout the night. It does this by simultaneously measuring the temperature of the water leaving the boiler unit and the temperature of the water returning after circulating through the mattress. It also offers an “AI Deep Sleep Solution” that automatically manages the mattress temperature via the “Navien Smart” app. It analyzes breathing sounds during sleep via a smartphone to determine sleep stages and adjusts the mat temperature accordingly. Users can also check their sleep quality and patterns, such as the time it took to fall asleep, actual sleep duration, and deep sleep duration.
Last year, KYUNGDONGNAVIEN launched the “Four Seasons Sleep Mattress,” designed for use in any weather. The Four Seasons Sleep Mattress is divided into “Air” and “Pro” models based on their operating mechanisms. The Air model utilizes indoor air cooled by air conditioners or other means to lower the temperature of the water inside the unit before circulating it through the mattress. The Pro model uses the “Peltier method,” which employs semiconductor cooling technology to cool the water before circulating it through the mattress.
The “Navien Magic” range hood, which ranked first in its category, effectively removes cooking fumes. Its flagship product, the 3D Air Hood, uses air curtains formed at the front and both sides of the unit to prevent cooking fumes from spreading throughout living spaces—such as the living room and bedroom—and helps expel them quickly. In addition, the “Dehumidifying Ventilation Air Purifier Magic Plus,” which integrates with KYUNGDONGNAVIEN’s dehumidifying ventilation air purifier, is a solution that provides comprehensive management of indoor air quality. While the 3D Air Hood exhausts cooking fumes, the dehumidifying ventilation air purifier supplies fresh air that has been thoroughly filtered, creating a healthy and comfortable indoor environment.
KYUNGDONGNAVIEN stated, “This award was made possible by the choice of customers who recognized the importance of optimal sleeping temperatures and the value of comfortable indoor air,” adding, “Moving forward, KYUNGDONGNAVIEN will continue to strive to provide an even more comfortable living environment based on our differentiated technological capabilities.”
