【Brand New】Doctor-Recommended Health Pillow for Stiff Shoulders, Yokurakune. "Motto Yokurakune" has a structure with independent left and right sides, and the high side gussets do not compress the shoulders, making it easy to sleep on your side! The sides are made higher to pursue the posture of sleeping on your side and the ease of turning over. The round quilting on both sides stabilizes the head when sleeping on your side and reduces pressure on the ears. The central concave shape also firmly supports sleeping on your back. 【How to Adjust the Height】 (1) Open the zipper on the back of the pillow and take out the adjustment opening cloth. (2) If you want to lower the pillow, remove a handful of filling from the adjustment opening of the area you want to adjust. If you want to raise the pillow, add a handful of filling from the included refill pack into the adjustment opening of the area you want to adjust. (3) After adjusting, roll up the adjustment opening cloth and put it inside, and close the zipper firmly. (4) Evenly distribute the filling by hand and try the feel on your bedding.
