Just after 3 hr nap. Setup easy, simple. Texture side is up. Contact is via skin. I think faster results per area of skin contact. I had shorts %26 halter top. Mat fit couch so my first try was there. Once plugged in had to keep struggling with my cat for me to lay down. Finally made it and there was room for the determined cat. we both slept 3 hrs. Migraine, gone. Glucose, down to normal, blood pressure, down to normal. (I had just taken vitals prior to delivery and delayed meds due to testing the mat). Win/win there. Still have tinnitus, tingling in feet less, edema in one instead of both. pleased with results for a 3 hr nap. Material of the mat is soft and comfy. You only need a mat for the area of the skin that will touch it the most often.
