"A New Type of Pillow" This pillow was designed according to the recommendations of sleep experts. It helps everyone relax their cervical spine and achieve deep sleep. This design helps everyone have a great night's sleep. "Environmental Protection of Inner and Outer Covers" Unlike other pillows, this pillow has a dust-proof and specially breathable inner cover, which more effectively extends the life of the memory foam core. The outer cover is removable, washable, and breathable, with a material composition of 40% bamboo and 60% polyester. The cover is machine washable, but do not machine wash the memory foam core. Store the pillow in a cool, dry place and avoid direct sunlight. "Unique Contour Design" The firmness of the pillow is medium. For back, side, and stomach sleepers, it keeps the head and neck in a natural position. This pillow is made of high-quality, high-density memory foam. The height of the pillow varies depending on sleeping position, head size/weight, body size/weight, and shoulder width (for side sleepers), and is maintained at the most comfortable level. "Safe and Healthy" Unlike other traditional pillows, this pillow provides a protective barrier. If there is an odor, it is the smell of "fresh raw foam" and is harmless. The smell should disappear within a few days after removing the pillow from the package and letting it air out. Immediate purchase is welcome! Check out other products here: #Ottotto'sShop
