Improved ergonomic curve for more effective neck pain relief. Our neck pillows have a thicker neck profile, larger shoulder area and adjustable height compared to other neck support pillows. The contoured pillow conforms perfectly to the natural flexion of the neck and shoulders, which more effectively supports, stretches and relaxes the cervical spine. A 70% reduction in body pressure and muscle tone maintains good blood flow to the head. Never wake up sore and stiff Adjustable loft, you're in control! The wrong size can cause headaches and shoulder, neck and back pain. Our adjustable pillows can be adapted to your size, shape or sleeping position by removing or adding a cushion (approximately 0.8 inches thick). Additionally, ergonomic neck pillows provide lower fluidity when sleeping on your back and greater fluidity when sleeping on your side. Rotate the pillow 180° to achieve minimal flow for low sleepers. Keep sleep balance and get ready for the most comfortable sleep!
