I recently purchased this mat. I have never been one for acupuncture. I am uncomfortable with needles at a doctors office let along getting them voluntarily used on me. But I stumbled upon this site one day. I ordered it and I love it.
They suggest using it for ten minutes and slowly increasing it’s use. That is what I was going to do. But then I leaned back on it and loved it. I could feel it loosening something in back near my shoulder blades. It was like all this pressure was being slowly released. And I have a bad neck and it just felt amazing. I ended up sitting on it for hours.
I think each person is probably different and I would follow the companies directions but I see why so many Swedes use it. Although one thing to note I did sit on it with shorts on and it felt a bit prickly. Also, I would not recommend sitting, laying, or using it quickly. on it. It was a bit startling when I mindlessly put my body on it.
