The Sooth-A-Ciser pillow was originally designed for home use as a natural traction device. By laying face up on the pillow, the weight of your head acts as a traction system, helping to alleviate tension headaches and neck pain by gently stretching the upper chest and anterior neck muscles. To use the Sooth-A-Ciser at home, all you do is lay face up with your neck supported by the highest curve. This cushion is not designed for sleeping. Many massage therapists think it works great for their professional use as well. In the clinic, the patented contoured design provides a comfortable lying position while elevating the face, shoulders and neck, giving a therapist better access than if you lay flat on your back, while also helping return the neck to its natural curve. Made of high-quality, precision-cut foam and a cotton blend cover for comfort and durability. 21" x 11" x 7". Care Instructions: Spot wash cover with luke warm water and a mild detergent.
