Memory Foam

【A Sleep Savior Really Helps】The ergonomically designed Adopt partition structure cervical neck pillow support your head, neck, shoulders, and back perfectly. By combining the benefits of a traditional bed pillow and a contour pillow, our ergonomic pillow is here to transform your sleep experience. The center cavity design properly cradles your head, naturally fits your neck's curve, and aligns your spine, allowing the entire body spine to be more efficiently supported, stretched, and relaxed.

【100% Slow Rebound High Quality Memory Foam】The side sleeper pillow is made of high-quality CertiPUR-US certified rebound memory foam. Premium quality firm and not too soft for maximum comfort and great relaxation of your head, neck, shoulders, and back muscles when you lie on your back or side. When you get the memory foam pillow, it is recommended to unpack and place it for more than 24 hours. After the pillow core rebounds completely and restores support, it will have a better sleep effect.

【2 Heights And Armrest Designs】Our cervical pillows have 2 different heights on both sides for you to choose（Lower Side-3.15", Higher Side 4.52"）, so you can choose the right one that is more suitable for your sleeping posture. The higher wing side is best for people who are used to high pillows or people with cervical spine problems, while the lower roll side is optimal for daily use of all sleeper types. And there are specific grooves that allow your arms to go under for comfortable sleep.
