I am a licensed chiropractor. I was interested in the concept of this mat. I always test the products I use on myself before I ever use them on any clients. I have to admit I am impressed. The mat is well-made and seems durable. My body felt very relaxed and loose because of the heat. When I got off, I felt refreshed and strong. I’m going to start offering chiro sessions on top of it if my patients are interested. I am sure it will help them feel a little bit better.
