【A New Sensation for Pillow Refugees! A Sleep Pillow That Achieves Your Ideal Sleeping Posture】 This is a height-adjustable, three-dimensional pillow developed to fit the unique head shapes and cervical spine curves of each individual. In addition to the design with different heights on both sides (low: 6cm / high: 8cm), it comes with two 2cm-thick adjustment pads, allowing for customization up to 12cm to your liking. The lower side is recommended for those who prefer to sleep on their back or are petite, while the higher side is recommended for those who sleep on their side or are large-framed. 【Carefully Designed for Smooth Turning】 The unique cut structure provides high breathability, dispersing the weight of the head while reducing the burden on the neck. It also prevents the filling from shifting, so the pillow won't collapse even when you turn over, maintaining the ideal height. With a fit that feels like you're being enveloped, it supports restful sleep that relieves fatigue. 【3-Layer Urethane Structure: High Resilience x Low Resilience】 It employs a 3-layer urethane structure that combines the gentle sinking of low resilience with the firm support of high resilience. It prevents the neck and head from sinking in, providing stability that makes it difficult for your sleeping posture to collapse. There is no pressure on the ears, and the design allows the bones in the neck to maintain a natural S-curve, effectively reducing fatigue in the neck and shoulders. 【Ergonomic Wave Structure】 The three-dimensional wave shape fits perfectly to the lines of the neck and shoulders, maintaining a natural curve in the neck even while you sleep. It also makes breathing easier, and is recommended for those suffering from a straight neck or stiff shoulders. You'll experience a change in your morning awakening, with a feeling like you're maintaining the same posture as when you're standing. 【Uses a High-Quality Tencel Cover - Easy to Care For】 The outer cover uses high-quality Tencel fabric with a smooth texture. It has antibacterial and deodorizing properties to prevent odors, and it's washable, so you can keep it clean. The inner cover also guards against dirt from entering the filling. It is resistant to deformation, and you can use it comfortably for a long time. 20
