ERGONOMIC DESIGN: Our ergonomically designed pillow positions your head, neck and shoulers in the ideal sleeping position. The pillow contours and semi-firm memory foam density ensures optimal spinal alignment and maximum support for both back and side sleepers, to give you a good night's rest and reduce neck and shoulder pain and aches. MEETS HIGHEST INDUSTRY STANDARDS: ErgoPillow is made from the highest quality materials that have been certified by OEKO-TEX Standard 100, one of the world’s most-recognized quality assurance labels for textiles tested for harmful substances. In addition, our product has been qualified as "Product Class 1”—the most stringent of all four OEKO-TEX certification standards, which means that the materials used have passed safety standards that make them safe even for infants and young children. HIGHLY RECOMMENDED BY HEALTHCARE PROFESSIONALS: Our pillow comes highly recommended by experienced spine and pain specialists for non-medical relief of pain caused by improper sleep positions. DUAL SIDE-SLEEPING ZONES: Choose from two sleeping zones depending on your preference for pillow height. Side Sleeper Zone 1 has a pillow height of 4.33” and Side Sleeper Zone 2 has a pillow height of 5.12” (refer to Features and Dimensions image). ODOR-FREE: Our pillows are aired in a ventilating facility after the manufacturing process to minimize harmless odors. However, if there are still some traces of a scent after unboxing, we recommend removing the pillow case and airing the memory foam in a well-ventilated and shaded area for a few hours until the smell dissipates. BREATHABLE PILLOW CASE: Our cervical pillow comes with a washable pillow case made of 80% cotton, and 20% mesh to promote maximum comfort and dissipation of heat.

If, for any reason, you are dissatisfied with our product, we offer a 30-day no questions asked returns guarantee. *Our pillows are not intended to medically treat patients who have neck injuries or are recovering from surgery.
