New, Unused Retail Price: ¥7980 [No Neck Pain] This low-rebound pillow combines the best features of a wave pillow and a contoured pillow. When sleeping on your back, your head fits into the wave shape and the central indentation, allowing your neck to stretch and maintain a natural S-curve in your cervical spine. When sleeping on your side, you can utilize the height of the edges, keeping your cervical spine parallel to the floor, relieving pressure on your neck and allowing you to wake up without neck stiffness. [No Shoulder Pain] This is a comfortable pillow that fits your shoulders perfectly. The curved shape snugly accommodates your shoulders, preventing pressure whether you sleep on your back or side. Furthermore, the height is designed to accommodate those with wider shoulders, preventing your shoulders from being crushed when sleeping on your side, so you won't have shoulder pain when you wake up. [Easy to Turn Over] This is a comfortable pillow with rounded corners. The entire pillow has a gentle curved design, allowing you to easily turn over with small movements without lifting your neck. There are no sharp edges, and the wide surface supports your cheeks, so you won't have marks on your face, and you won't wake up in the middle of the night due to pain. [Height Adjustable] This is a comfortable sleep pillow with 4-level height adjustment. By combining the included adjustment cushion with the front and rear height differences of the pillow body, you can choose from a low setting of 8cm, standard settings of 10cm and 11cm, and a high setting of 13cm, allowing you to finely adjust the height to match the depth of your neck curve and sleeping posture. [Doesn't Sink In Deeply] This low-rebound pillow is made with a unique formulation technology. It holds your head in place, and while it is low-rebound, it has a slightly firmer feel, so your head doesn't sink in deeply, and it doesn't put extra strain on your neck and shoulders. It also solves the stickiness, odor, and hardness changes due to temperature of conventional low-rebound pillows, allowing you to sleep comfortably regardless of the season. [Comfortable in Summer] This comfortable sleep pillow comes with a cooling contact cover. The smooth fabric feels cool to the touch. It also has a breathable inner cover, so heat doesn't build up in your head during sleep, and it blocks dirt and moisture. You can sleep comfortably all night, and it's a low-rebound pillow that doesn't feel stuffy in the summer.
