The TAO Soft series in one of the newest additions to the HealthyLine product line. Unlike most series, it doesn’t have a lot of size variations. The TAO Soft series has a king and queen model and a small model. The king and queen models are sized to cover the entire surface of prospectively-sized mattresses. Since these mats are generally used in a bed they have independent left and right side controls for up to 2 people to set the device to their preference. Control the temperature to the exact degree so both people can sleep comfortably throughout the night. The TAO Mat Small is an extremely lightweight, flexible, and versatile device that you can use to target small areas of your body like your lower back, abdomen, or bottom. It is easy to store between uses and the perfect device to take with you while you are traveling. The TAO Soft series is one of the most comfortable models we have made to date. It is made entirely out of crushed tourmaline, amethyst, obsidian, and for the first time ever Jade! Four stones at the same time offer the next level of gemstone therapy. Choose a TAO Soft model and stimulate your wellness levels in complete comfort and relaxation.
