It is heavy because it contains amethyst. It can be used as a mat to place on your lower back, etc. It's better to store it spread out rather than folded. It's been 7 years since I purchased it. I have tested its operation right up until recently. Please refrain from purchasing if you are overly concerned with perfection. Mat only, for sale.
