Brand new, unused! Instant purchase welcome! 【No Neck Pain - Ergonomic, Supreme Fit】 Designed to address the concern of "feeling discomfort around the neck when waking up." The 3D structure supports the head, neck, and shoulders without gaps, maintaining the natural curve (S-line) of the neck while sleeping. It doesn't force unnatural postures, making it easier to secure airways, supporting smooth breathing and deep sleep. Experience a refreshing wake-up every morning. 【60D High-Density Memory Foam - Enveloping Comfort】 The core material of this pillow uses 60D high-density memory foam, which is durable and shock-absorbent. It's finer than typical pillows and slowly sinks in to match the weight of your head. The perfect balance of not too hard and not too soft evenly distributes body pressure, reducing pressure on the neck and shoulders during sleep. It's resistant to sagging even after long-term use, providing consistent support. 【2-Way Height Adjustment - Suitable for Back/Side/Stomach Sleepers】 Sleeping postures and body types vary. This product features a design with different heights (6cm/10cm) at the front and back, allowing for "height adjustment." You can freely choose the higher or lower side by simply changing the direction to suit your condition and preference. **It's perfect for side sleeping, which requires height, and the standard back sleeping position, and using the lower side is also ideal for stomach sleeping.** You're sure to find your perfect "sleep position." 【Excellent Breathability - Washable Cover for Year-Round Cleanliness】 Because it touches your skin every day, we've focused on cleanliness. The double-cover structure, with excellent breathability, quickly wicks away sweat and moisture, keeping your skin dry all night long. The outer cover is zippered and easily removable for machine washing. Even those concerned about the proliferation of dust mites and bacteria can always use it in a hygienic state. 1580r10497
