Contour design: the contour design supports and aligns the head, neck, shoulder and back, helping to reduce the strain on the cervical vertebra and spine and ultimately relieve pressure and discomfort. • Two height support: Two height options are suitable for both back and side sleepers. The higher side is ideal for those with cervical problems, while the lower side is perfect for all other back/side sleepers. • High-quality memory foam material: made of high-quality memory foam, this pillow adapts to the natural contours of your body and uses the innovative 5S slow rebound technology to provide evenly firm support and amazing comfort. • Breathable ice silk cushion cover: the breathable, chemical-free cushion cover is machine washable and has a design with zip. The ice silk pillowcase also ensures that the pillow stays cool while sleeping, so you can keep it comfortable all night long. • Please note: the memory foam itself produces a very weak smell. If you can’t accept it, please air it within 3-5 days.
