The mat emits far and mid-infrared rays with 93% efficiency in the most absorbable wavelength range between 4 and 16 microns. Amethyst crystals refract, and geometrically structure the infra-red light to penetrate 6-8 inches (15-20 cm) deep.

Ereada® Amethyst Mat uses the highest quality most precise in the industry Bi-Metal heat sensors to control heating functions within the different layers of the mat.

The mat generates anions through distinct layers and electrical discharge function of the controller and directly conduct them to the tissues. Also, you can activate the air ion function by the "Ion" button of the controller.

Single Amethyst mattress features 16 pcs of visible Red Light LEDs. 660nm Red Light Stimulation phototherapy is considered excellent for improving the look of skin. Each of the Korean red LEDs generates 6-10 times more lighting energy than the same size LED made in China.

6. Negative Potential functon makes Ereada® distinctive

A big advantage of Ereada mats is that in addition to Negative ion emission layers, our Rich Brown Amethyst mats (Midsize and bigger) and some of Rich Brown and Gemstone Mini Mats are equipped with an advanced Negative Potential (N.P.) generation system called also Electrical Discharge of Negative Ions (E.D.N.I).

- N.P. creates Electrostatic Field with 600 volts of Negative Potential converted at low speed into DC energy through the special Silver Fiber layer. It converts the mattress into a bath of anions into which you can sink your whole body.

- Negative Potential function helps to support the potential and the natural electrical fields. It is the most powerful technology for inducing the negative ions in the amounts sufficient to alkalize.

- N.P. function is available only in the Rich Brown Ereada® mats manufactured in Korea by Hyundai and in Richway BioMats ( E.D.N.I. ). Ereada® mats are the only ones with this function installed into the mini mats 20x32 and midsize mats 24x59 inch.

- Negative Potential generation acts synergistically together with the Negative Ion function in maintaining the natural electrical potential level and providing multiple benefits known by practitioners and therapists. It is also important that N.P. is included into our mat for a small fraction of the cost of the special Negative Potential devices.

Ask a Question
  • What is mean when you said that the Purple Ereada is not equipped with direct current negative potential (N.P.)?

    Hello Roger,
    Thank you for your question.
    All Ereada Amethyst mats generate negative ions by inner anion layers and crystals.
    Brown mats have an additional silver fiber layer generating negative potential. It is a static negatively charged field surround the mat.
    Purple and Gray mats do not have this function, but they feature pulse magnetic fields (PEMF). Also, their controllers can release air ions.

  • How long do I use it for? Do I sleep on it over night or just lay on it for an hour or so?

    For pleasure people use amethyst heating mats from one hour on high temperature to 12 hours on warm temperature daily. You can try and see what kind of sessions gives you the most benefits. We always recommend to start with the lowest or medium temperature levels 1-3 or 30-45°C for short periods of 20 - 30 minutes to see how your body reacts and then gradually increase the temperature and the length of the session over time. 

    You can certainly sleep on the mat over night but it is best to first get used to mat's hardness. Please, use only the lowest temperature settings (levels 1-3) for sleeping.
