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'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.
