Gray Ereada Amethyst Mat Single

Gray Ereada® Amethyst Mat Single Size

In addition to deep-penetrating tissues crystal FIR heat and Negative Ions, Gray Ereada Amethyst Mat also produces Pulsed Magnetic Fields and Air Ions. It is a top reason for regular using the mat to relax and reenergize even without heating.

You can use this Amethyst mattress for sleeping as well. Just be sure that the heat level is on the lowest first or second heating level, or use the mat for negative Ions only during the night time to not fall asleep on the hot mat and dehydrate. If you are falling asleep, the best way to use it is to turn off the PEMF function after the first cycle (so it does not overstimulate you or wake you up when it resumes). 

If you feel that 8 hours is too much, use an external plug-in timer. A heavy-duty one with a built-in surge protector may be the right choice for double protection in the nighttime. 


The Mat set Includes:

  1. Ereada Amethyst Mat 
  2. Controller with terminal and plug wires
  3. Waterproof but FIR and Ions Permeable Thick Protector Pad and Thin Waterproof protector  for use on top of your Mat
  4. Bag for storage and carrying the mat
  5. Owner's Guide and paper sheets with additional info 

We developed a family of Multilayer Waterproof covers with breathable TPU membrane for our Mats. Please, do not be confused if you receive your mat with the white Protective Cover on it.  The cover is shipped on the Amethyst mattress to protect it during delivery. Just remove the white sheet, and you will find precisely that mat which you ordered beneath. 


Adjust FIR warmth between seven levels in the range 86°F~158°F or 30°C~70°

  1. Level 1 is 86°F or 30°C ( used for Negative Ions and Potential, all-night sleep low heat mode )
  2. Level 2 is 98°F or 36°C ( Low mode )
  3. Level 3 is 110°F or 43°C ( Low, medium mode )
  4. Level 4 is 120F or 49C ( Medium mode )
  5. Level 5 is 133°F or 56°C ( Medium-High mode )
  6. Level 6 is 145°F or 63°C ( High mode )
  7. Level 7 is 158°F or 70°C ( Highest mode )

Adjust PEMF Magnetic Wave frequency between nine settings in the range 8~64 Hz 

  1. Level 1 is 8 pulsations per second (8Hz) which is the fundamental frequency of the first harmonic of Schumann resonance. 
  2. Level 2 is 16 pulsations per second (16 Hz)
  3. Level 3 is 24 pulsations per second (24 Hz)
  4. Level 4 is 32 pulsations per second (32 Hz)
  5. Level 5 is 40 pulsations per second (40 Hz)
  6. Level 6 is 48 pulsations per second (48 Hz)
  7. Level 7 is 56 pulsations per second (56 Hz)
  8. Level 8 is 64 pulsations per second (64 Hz)
  9. Level 9 is the random program auto-changing frequencies between 8 and 64 Hz every 1-2 seconds.
  • The PEMF program cycles 20 minutes ON and 100 minutes OFF. It repeats four cycles if you set the timer for 8 hours or more extended sessions. The gauss output for the PEMF is 100 to 400 Gauss depending on the frequency (higher frequency -> higher gauss). If you repeatedly press the PEMF button and the main display changes numbers from 1 to 9, it means that you have an advanced controller able to set PEMF level and frequency. Both the regular controller and variable rate one are interchangeable.
  • Air Ion releases ions into the air in addition to those negative ions produced by mat layers. It has 1-hour auto shut-off.
  • You can also manually deactivate the PEMF function at any time, and in this case, cycling will be interrupted. Or you can re-activate it, and the lights will be ON.
  • You can also manually deactivate the Air ion function at any time. Or you can re-activate it, and the lights will be ON.
  • If you would like to use PEMF continuously (30-60 minutes), you need to manually reactivate the PEMF function by pressing the appropriate button every 20 minutes when it stops. But it is not recommended to use PEMF continuously for more than 30 minutes during the use of heating function at higher than the 3rd level.

You can use the mat in several modes all together or each separately:

  • Only Heat / FIR
  • Only Negative Ion
  • PEMF
  • Air Ion
  • Combination of Negative Ion, Air Ion, PEMF, and Far-Infrared Light together

We make our regular mats for the U.S. voltage 110-120V/60 Hz. These mats work fine in the U.S.A., Canada, Mexico, or Japan. 

If you need to use your mat in Europe, Asia, or South America, select or ask us for 220-240V/50 Hz mat. These mats come with the universal European plug.

110-120V mats do not work in 220-240V countries and vice-versa unless you use the step up and down power converter transforming voltage. If you connect your mattress to the power outlet with the wrong voltage through a simple travel adapter, you will damage it.
