Prickly but great

I bought this mat out of desperation; I had terrible hip pains and shoulder pain, and was trying all sorts of things both herbal and mechanical to find relief. I found the Spoonk Mat (I hate that name btw) at a natural pharmacy and took it home.

The mat is covered with hard plastic circles, each of which has sharp bits on it. Not enough to break skin, of course but all the same I'd recommend you put some clothes between you and the mat when you're starting out. I angled myself on the sofa so the aching hip would be resting on the mat, which felt very peculiar and uncomfortable. But gradually, it started to feel really good, and when I removed it I rolled it up to stick behind my shoulders and upper back, and it felt amazing!

You can also lie on it in bed for meditative or other qualities. They warn you not to sleep on it but let's be real, it's bound to happen.
