Used in excellent condition. Perfect for meditation and healing. “The Biomat is a healing mat filled with amethyst crystals that emits Far Infrared light and Negative Ion technology. It emits a range of different temperatures for distinct uses. It can be used to sleep on, do healing treatments, for sauna sessions, and overall health and wellness.” Has been covered since they purchased it, as seen in the pictures. Pet free, smoke free home. Helping my grandparents, former reiki masters, find a new home for their amethyst mattress which they can no longer use, because they can no longer get down onto the mat. If purchased brand new would cost about 1850. Has a gemstone certificate, and all original paper work. Make an offer.
