The comfort in sleep gies a day of energy in the short term as well as lifelong health and happiness in the long term. The Onsu (warm water) mat of Xdream has been created through a sleep science research, provides comfortable and cozy sleep with out electromagnetic waves, and fulfils our desires for quality sleep. It gives you a refreshed feeling in the morning even after an hour of sleep on it. We want to have our children sleep in a warm and comfortable place. We don&＃39;t want to expose our precious children to electromagnetic waves. Our parents suffering from back and muscular pains want the warmer part of an ondol room. Xdream makes all these possible.
