Highlights This cervical pillow is made with high-quality memory foam. It fits ly and supports the natural curves of your neck and head, which provides pressure relief for your head and neck while you sleep. The fabric we use is skin-friendly, and you will feel comfortable when your face rests on the pillow. This pillow is suitable for all sleeping positions. Whether you sleep on your back, side, or stomach, you can sleep comfortably. The height of this Orthopedic Pillow is adjustable. It consists of three memory foam inserts, and you can adjust the height by adding or removing different amounts of inserts. The pillow's normal height is 4.7 inches at the top and 3.9 inches at the bottom. By removing the middle layer, the height can be reduced to 3.5 inches at the top and 2.8 inches at the bottom.We used dynamic foam, which won't get stiff in cold weather. It maintains consistent firmness and comfort year-round, unlike most memory foam pillows on the market. The pillowcase is made of high-quality breathable fabric to help keep you cool while you sleep. The pillowcase is removable and MACHINE WASHABLE. The pillows come as a set of two and will be shipped in two separate packages. After unpacking, the cervical pillow will have a certain smell of memory foam. This is normal and not harmful to the body. We recommend leaving the pillow in a well-ventilated area for 24 or 28 hours before use.  Item Dimensions 23.62"L x 14.17"W x 4.72"H Item Weight 2.97 Pounds Material Type Memory Foam Fill Material Memory Foam Material Features Breathable Fabric Type 60% Polyester; 40% Viscose Product Care Instructions Machine Wash Special Features Compressible, Cooling, Removable Cover Item Firmness Description Soft Age Range Description All Age Number of Pieces 2 Package quantity 2
