[Head Stability Support and Spinal Alignment Adjustment with Central Concave Structure] This product adopts a central concave structure that gently cradles the head. This indentation naturally fixes the position of the head, preventing unnecessary head movement during sleep. As a result, unnecessary strain on the neck and shoulders is reduced, and it supports maintaining the ideal spinal alignment from the head to the neck and lower back in a straight line during sleep. This design is especially recommended for those who feel tired in their back or lower back during the day, such as from desk work, or those who feel neck pain when they wake up in the morning. It provides stable and relaxing support, just like receiving a correction from a chiropractor. [Unique ARC Curve Design Perfectly Fits from Neck to Shoulders] Based on ergonomics, the "ARC curve" has been adopted, thoroughly researching the natural curve of the neck. This curve is designed to fit snugly from the base of the neck to the transition to the shoulders, filling any gaps. This distributes the load on the cervical spine, significantly reducing the burden on the neck during sleep. You'll experience the ultimate fit, free from the feeling of your neck hanging or being uncomfortably compressed. This is a core function that we especially recommend to customers with shoulder and neck problems. [Both Sides Higher Design Considering Both Side Sleeping and Back Sleeping] The sides of the pillow are designed higher than the center, so when you sleep on your side, your head is kept at the appropriate height, reducing pressure on your shoulders and arms. Furthermore, this higher area guides your body into a natural supine position without strain, supporting the correction to an ideal sleeping posture. It promotes smooth turning over, rather than staying in the same position all night, and has multiple effects of reducing the burden on one point of the body. This design is also satisfactory for those who cannot maintain a stable sleeping posture and frequently toss and turn. [Easy Height Adjustment to Your Preference] This product has a height of approximately 9cm/approximately 14cm, and you can easily adjust the height of the pillow. You can adjust it to your own physique, preferred sleeping position, and your physical condition on that day. TOUMON [Japanese Company Sales] 5202-A3880$$3880
