【Brand New】Doctor-Recommended Health Pillow for Stiff Shoulders, Yokurakune (Side-Comfort Sleep). "Motto Yokurakune" features a structure with independent left and right sides, and high side gussets that don't compress the shoulders, making side sleeping comfortable! The high sides are designed to facilitate side sleeping posture and easy 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 provides firm support for back sleeping. 【How to Adjust the Height】 (1) Open the zipper on the back of the pillow and remove the adjustment opening fabric. (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) Once you've adjusted the height, roll up the adjustment opening fabric and tuck it inside, then close the zipper securely. (4) Even out the filling by hand and test the comfort on your bedding.
