This is a memory foam pillow that 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. This is a comfortable sleep pillow that fits snugly on your shoulders. The curved shape fits your shoulders perfectly, preventing pressure on your shoulders whether you sleep on your back or side. Furthermore, the height design is suitable for those with broad shoulders when sleeping on their side, preventing your shoulders from being crushed, and you won't have shoulder pain when you wake up. This is a comfortable sleep pillow with 4-level height adjustment. By combining the included adjustment cushion and the front and back height differences of the pillow body, you can choose from a low height of 8cm, a standard height of 10cm/11cm, and a high height of 13cm, allowing you to finely adjust the pillow to match the depth of your neck curve and sleeping posture. This is a comfortable sleep pillow with a cool-touch cover. The smooth fabric feels cool to the touch. It also has a breathable inner cover, preventing heat from building up in your head during sleep and blocking dirt and moisture. You can sleep comfortably all night, and it's a memory foam pillow that doesn't feel stuffy even in summer.
