Enhances your Sleep Quality

Sleeping-posture is a key to reach the “high quality sleeping”. If you feel tired when you wake up, you might be sleeping in a wrong posture. According to dynamics study, an ideal sleeping-posture is when a spinal code is curved in S-shape. Also, when the body pressure is concentrated at one spot, the exhaustion worsens due to the blood flow congestion. Therefore, an ideal bedding is to help spreading the body pressure evenly, as well as let the body turn over comfortably while asleep.
