The Sobakawa Cloud Pillow is the amazing pillow that is 300 years in the making. Based on traditional Asian buckwheat pillows, the Sobakawa Cloud Pillow is filled with over 20 million air beads. It"s like sleeping on a virtual sea of clouds. Ordinary pillows are hard and flat like bricks. The Sobakawa Cloud Pillow is crescent-shaped and anatomically designed to follow the contours of your neck and shoulders. As you move, 20 million air beads move with you and absorb your movement, maintaining both comfort and support. After sleeping on the Sobakawa Cloud Pillow you"ll awake rested and refreshed, every morning. Don"t forget the special Sobakawa Cloud Pillow pillow cases. Specially designed to fit the Sobakawa Cloud Pillow"s unique crescent shape, these pillow cases breathe and continually adjust to the shape of the pillow, allowing the air to flow freely and keep your head cool. As a special bonus, you"ll have the option to get one free pillow case (plus additional processing) when you order an original-sized Sobakawa Cloud Pillow.
