Moririn Co., Ltd. Harumeku My Waist Pillow Unused item. Taken out of the bag once for photography. Just add a "second pillow" to reduce the burden on your posture while sleeping! Improves the quality of sleep. Harumeku developed this "waist pillow" together with Mr. Adachi, a senior sleep improvement instructor. For those with a hunched back, place it under the waist. For those with swayback, place it under the knees. It guides you to a gentle S-shaped sleeping posture. Although it is only a few centimeters thick, The difference from your usual posture is significant, and Because the risk of hurting your lower back is high, It is intentionally made this thin. When placed under the waist, the patented inner material fits on both sides and supports the body moderately. This structure was also consulted with Ryōhei Aoki, a physical therapist who is knowledgeable about lower back problems. "I have swayback, so I put it under my knees. My body relaxes, and I can sleep soundly. It's amazing," says Adachi, who is also satisfied with the result. With a smooth brushed fabric and mesh reversible design, you can sleep comfortably all year round.
