Memory Foam Pillow for Neck Pain Relief, Adjustable Height [Ergonomic Design, Shoulder Pressure Distribution] for Side Sleepers and Back Sleepers, Sleep Support, Includes 2 Washable Mesh Covers ☆ About This Product ☆ [Professional-Recommended "3D Three-Dimensional Support Design"] This design supports the head, neck (cervical spine), and shoulders in three dimensions. It maintains the natural curve of the neck and guides the entire spine into ideal alignment. Whether you sleep on your back or side, it evenly distributes body pressure, reducing shoulder stiffness and neck pain, and allowing for a deep, restful sleep until morning. [Choose from 2 Heights to Find Your Perfect Fit] You can use both sides of the pillow to select from two heights: 5.5cm (low) and 10.5cm (high). You can choose the optimal height based on your body type, sleeping position (back sleeper or side sleeper), and preferences, allowing you to maintain a natural, comfortable posture. [Not High-Resilience, but "Low-Resilience." 60D High-Density Material Gently Envelops] Unlike typical high-resilience pillows, this pillow uses high-density low-resilience memory foam. It supports the weight of the head and neck over a wide area, relieving pressure concentrated on a single point. The slow rebound conforms to the body, providing stability that makes it easy to turn over. [Includes "Double Mesh Covers" with Excellent Breathability] Includes a set of two covers made of soft, breathable mesh material. This promotes internal air circulation, reducing stuffiness and heat. They are easily washable in a washing machine, so you can maintain cleanliness and enjoy a fresh, cool feel at any time. SV931 60 or more
