The popular, economically priced EconoWave Pillow features a wave shaped surface which provides even support and allows air to circulate for increased comfort while you sleep. Designed to help alleviate headaches and neck pain, this pillow helps restore the natural curve of the neck while sleeping on the back. Constructed with high quality foam, the EconoWave Pillow provides gentle support. Two different sized lobes provide different support options. Use the larger neck lobe for maximum support or the smaller neck lobe if you are in the adjustment phase or if you prefer slightly less support. It may take some time to adjust to this cervical pillow and immediate overuse may increase neck pain. Those who slowly ease their way into orthopedic correction by alternating between this pillow and their current pillow achieve the best results. A washable cotton/polyester cover is included; pillow conveniently fits into your favorite standard pillowcase. 22 x 15 inches (56cm x 38cm) with 4 1/8 inch (10cm) and 4 7/8 inch (12cm) lobes. Latex free.
