The Healthy Wave Mat Amethyst Far Infrared Heat Shoulder Mat is a specially designed mat that is worn similar to a vest covering your upper back, shoulders and chest with 2 straps to keep it in place. Its design allows you to wear it while sitting up which is ideal if you want to use it while sitting on a couch or at a desk leaving your arms free. The crushed Amethyst crystals allow the mat to easily form around your body for maximum effectiveness and provides a focused stream of far infrared heat. It can also be laid out flat and used as a tradition style mat.
This device also doubles as a knee device that you can target with the same far infrared heat. Just wrap the mat around your knee.
