If your idea of a good pillow is simply a bag filled with feathers, get ready for some comforting news. The CerviTrac Pillow features a multi-channel design engineered to allow you to choose the support level you need while limiting fiber migration. This unique design helps relieve spasms, alleviate minor tensions and maintain or resume the natural cervical curve of your neck while at rest. The CerviTrac Pillow’s recessed center provides maximum comfort and flexibility. When sleeping on your back, the center cradles your head to support your neck in its most natural position. As you roll from your back to one side or another, the raised side channels provide the proper support to gently hold your neck in a comfortable position. By supporting your head and neck in a proper sleeping posture, the CerviTrac Pillow can help relieve pain from neck injuries and prevent airway blockage (a major cause of snoring). Most people experience an increase in sleeping comfort within a couple of days. Others may require up to two weeks before the neck and back muscles adjust to their proper position. Either way, restful sleep is on its way. Laundering Instructions: 1) Soak in lukewarm water using mild detergent 2) Continue to press or flush water through until clean.
