I have both this amethyst bolster and the Jade pebble bolster. I am an acupuncturist and I use them in my practice for my patients. My neck pain people really love this addition. The firmness and the heat really help soothe and relax the muscles and tension. I have a full mat on my table, one bolster for neck and one for under the knees. No one over wants to get off my table! It is so cozy and feels so good! You won’t be disappointed with this bolster!

Purchased the bolster with my full-size mat. Awesome neck relief! I even use it sometimes on my lower back whenever I experience any stiffness

This pillow brings relief to my neck and helps to alleviate pain. Very good product!

Absolutely amazing device! I can't name any minuses, due to this pillow I forgot about all my chronic diseases that had tortured me for years. Now I'm planning to buy the infrared mat of this brand looking forward to more astonishing effects.

I would never have bought this pillow myself, but a friend of mine gave it to me for my birthday, so I began using it. I was greatly surprised after only one week of using it as my regular headache disappeared! I proceeded the usage and noticed that I felt and looked much better, and so I do now.
