Medicrystal LLC is an American company focusing on High End Heating Mattresses and other products made of natural gemstones as Amethyst, Jade, Agate and Tourmaline. We have personally experienced great benefits from the Far Infrared Heating Mats with precious crystals and have decided to make them available to our customers for an affordable cost.

MediCrystal® Classic FIR Amethyst Mat collection in reddish Brown color is presented in 4 sizes mats: Mini, Medium, Pro, Queen, matching Pillows and a Micro Mattress Pad (FIR Belt).

This Amethyst Mat product line is called “Classic” because almost all the surface of the mat is covered with the soft to touch luxury eco-leather. Amethyst gems abundant across the entire mat surface from edge to edge are visible only through the triangle window made of heat resistant transparent urethane film.

Originally the similar classic functional design was invented by Richway Biomat Company more then 20 years ago to provide softer experience then that of bare hot stones not covered by the fabric.

MediCrystal® mats are distinctive from both the original Richway bio-mat and many copies of other brands by the triangle shape of Amethyst showing window. In difference with competitors the window is optimally positioned in the middle of the mat to add more heat to the spine cord zone. This shape has a unique visually appealing appearance and reminds the Amethyst crystal structure. This distinctive design is both elegant and luxury.

The main feature of the MediCrystal® Amethyst Mat 17 layers system is the thick layer with thousands Untreated, Unpainted, 100% Natural Purple Amethyst crystals. When warmed amethysts and other stones naturally emit FIR rays and negative ions. Amethyst crystals isolate and concentrate Infrared rays in the most absorbable wave length range 4-16 µm to penetrate up to 8 inches deep.

In the same manner hot crystals naturally release mat negative ions restoring the natural electrical fields and potentials. It helps to keep fit and support immunity on normal optimal level.

Classic FIR Amethyst Mattresses of Mini and Micro size (Belt attachement pad) may be used to focus on specific areas as lower back, legs, knees, shoulders, elbows, joints, or other parts of the body.

Larger MediCrystal® mats as MidSize and Professional ( PRO ) series are great for the whole body sessions. The Queen Amethyst Mattress even allows two persons to simultaneously use the mat with separated two zone temperature and session time control.
