MediCrystal Mat Review (2026): Pros, Cons, and Which Model to Buy

MediCrystal mats are some of the most feature-packed gemstone mats on the market.

Some models combine far infrared heat with PEMF, red light, crystals, and negative ions, while others keep things much simpler.

That sounds impressive, but it also makes buying one confusing.

In this review, I’ll show you which MediCrystal mats are actually worth considering, which models are best for sleeping vs short sessions, and what you should know before spending a few hundred dollars on one.

Here’s a short comparison table before we start:

Who is MediCrystal?

MediCrystal says it started in 2015 as a family-run American company and is currently incorporated in Wyoming. The company sells gemstone heating mats, PEMF mats, and wearable heating pads through its own site and Amazon listings.

The products are manufactured in China, according to the company, in factories that it says are ISO, TÜV, CE, and FDA-registered.

MediCrystal also offers a 45-day trial and 1 to 2 years of warranty, depending on the model.

We also appreciate their offering special discounts for veterans, military personnel, nurses, and doctors around the world.

Where is Medicrystal Made?

Medicrystal mats are manufactured in China in factories the company says are ISO/TÜV/CE and FDA-registered.

These factories have 10 years of experience in making hot stone mats.

That is not unusual in this category. Many infrared mats and gemstone mats sold by U.S. wellness brands are manufactured in China and then sold under an American brand with U.S.-based support.

Medicrystal Mats Review: The Good, the Bad, and the Sweaty

The main thing MediCrystal does well is stack functions into one mat.

If you want a mat that combines heat, gemstones, and sometimes PEMF and red light, MediCrystal gives you more options than many simpler infrared mat brands.

The biggest downside is that more features usually mean more bulk, more stiffness, and more things that can eventually fail.

So the real question is not “Is MediCrystal good?”

It is: Do you actually need the more advanced functions, or would a simpler FIR mat do the job just as well for you?

Unboxing the MediCrystal Mat: All You Need to Know Before You Buy

Here’s what you’ll find in MediCrystal gemstone mats:

1. Infrared & Red Light Therapy

Most MediCrystal mats deliver natural infrared rays through low-EMF heating of semi-precious and certified stones that make the primary part of the 17-20-layer system of the crystals forming the surface of the mat.

These natural gemstones are lined in eco-suede tubes or fixed with man-made mesh fabric by an artisan sewing process.

The heated stones emit mostly mid-/far-IR (peaking around ~8–10 µm at typical mat temps), which warms superficial tissues; the PEMF/Photon models add 660-nm LEDs for photobiomodulation.

Infrared light therapy is a proven (and highly researched) to help with many health conditions, including pain relief, injury healing, blood circulation boosting, body temperature raising, detoxing through sweating, and much more.

All hot stones emit full-spectrum infrared rays starting from NIR and transfer most of the energy in the form of FIR.

Red light therapy (650 nm – 850 nm) is mostly useful for skin problems (such as cellulite, eczema, and scars) and anti-aging (wrinkle reduction, skin toning, etc.). It penetrates only up to 2 mm into the skin.

Only the PEMF collection (infrared & PEMF mats) includes red light therapy biostimulation.

2. Healing Crystals

All MediCrystal mats are built with 100% natural Grade A+, untreated, non-painted, non-irradiated purple amethyst from South America.

The mats include other stones, such as Tourmaline, Jade, and Agate.

They are quite similar in their function and benefits, but there are a few differences:

Amethyst is considered the main healing stone because when it is heated, it emits natural rays in a bio-compatible and bio-resonant range to the human body.

That’s why Amethyst is the main gemstone used inside the mats (at least 50%).

Black Tourmaline stones are mainly used for negative ion generation because they are “baked” with volcanic rocks, yellow clay, and other minerals to make them emit the healthiest level of 700-1500 ions.

Negative ions are proven to relieve stress and improve overall well-being. You can feel them most near waterfalls and big rivers.

Red agates have been used as healing stones since ancient times. They were well known for their many different healing properties.

3. Low Flexibility

Most MediCrystal mats are not flexible and are not meant for folding around different areas of your body.

For localized treatments, such as knee arthritis, we recommend an infrared knee heating pad.

The low flexibility is caused by the high-density compressed cotton layer at the bottom of the mat, which insulates it and directs the heat up toward your body.

PEMF mats would be even stiffer.

All mats are recommended for use on a flat surface; however, the classic FIR collection can be folded for placing on a chair:

4. Low EMF Heating Systems

MediCrystal markets its mats as low-EMF or EMF-free, depending on the model, and some listings state measurements under 2 mG by specification or lower in their own testing materials.

If low-EMF design is one of your top priorities, it is still a good idea to ask the company for the exact specs for the specific model you plan to buy.

Full protection from harmful EMFs is provided by EMI (Electro-Magnetic Interception) technologies integrated into the mats.

Here’s recent testing posted on YouTube:

5. PEMF Therapy – Pulsed Electromagnetic Fields

Some MediCrystal models add PEMF using built-in coils and preset or adjustable frequencies, depending on the collection.

The company’s 4-Gems models use preset frequencies like 4, 8, 10, and 14 Hz, while some Photon models allow 1 to 30 Hz adjustment.

PEMF (pulsed electromagnetic field) function generates low-frequency magnetic pulsations, researched and used for nerves, bones, and joints for 50 years.

PEMF mats emit magnetic fields that are almost identical to frequencies created by cells, organs, bones, and tissues, alternating at 1-30 Hz rates.

This pulsation brings more energy and has more powerful effects with the same or even lower-intensity magnetic fields.

Some of the proven benefits include migraine and headache relief, sciatic nerve regeneration, back and neck pain relief, osteoarthritis, fibromyalgia, fractures, edema, chronic wounds, and more.

(See the full list of studies here)

Several models of MediCrystal mats, pads, and belts come with pulsed magnetism copper loops inside. The smaller devices (belts/vests) have 1-3 coils, while the larger mats have up to 11 coils throughout the heating area.

PEMF reaches a maximum level of 50-100 Gauss on the surface of the mattress.

6. Warranty and Trial

All MediCrystald products come with a 1-2-year warranty and a 45-day free trial. Shipping and return are free for warranty issues.

The classic amethyst mats and tourmaline mats come with a 2-year warranty, which is more than the average 1-year warranty common on this market.

How Do You Choose a Medicrystal Mat?

The easiest way to choose is to answer this first:

Do you want a mat mainly for sleeping and low-heat comfort, or mainly for short, more therapeutic sessions?

If you want to sleep on it, the classic FIR-only mats are usually the better choice.

If you want PEMF or red-light features for short sessions, one of the more advanced models makes more sense.

1. Do you really need a photon red light? Or PEMF therapy?

If not, you can choose one of their professional gemstone infrared heating pads, according to the size you need (full body/back treatment, etc.). These mats also come with a longer warranty.

2. Do you want to sleep on the mat?

If you want to replenish your energy and treat chronic pain by sleeping (on low heat) for several hours on a mat, the classic mats without the extra functions are the best choice.

The mats with PEMF therapy are bulkier and more uncomfortable to sleep on, and are more effective for short (yet highly effective) treatments. It’s not recommended to move around on them.

Also, the mats with the triangle design, V-mats, and those covered with suede are softer than the mats with mesh fabric covering the crystals.

However, if you want to enjoy the benefits of acupressure, the harder mats would work better.

3. What size do you need?

The mini mats are better for localized use, such as the back and legs, when you don’t want the whole body to receive thermal treatment.

The mini mats (32″ x 20″) are still big enough (and hot enough) to produce a lot of sweat and get the benefits of detox. It will just take a bit more time.

(For detox and full body treatments, we recommend a portable far infrared sauna).

The midsize and compact pro models are somewhere in the middle and are a good choice for regular-sized people.

The pro sizes are better for full-body hyperthermia treatments, and the effect is similar to infrared sauna treatments.

Make sure to consult with a professional before you do high-heat detox sessions, and hydrating is critical.

Here’s how to choose according to your height:

• 5’5″ and under – 59″x24″ midsize mat
• 6’0″ and under – 72″x24″ full-body mat
• 6’1″ and over – 71″x32″ professional or 75″x39″ single size mat

MediCrystal vs. Biomat

If you are deciding between MediCrystal and Richway BioMat, the simplest difference is this:

BioMat is the more established premium brand and is known for durability, but it is much more expensive.

MediCrystal gives you more model variety and more feature combinations, especially if you want PEMF or red-light options at a lower price point.

If your main goal is a high-end classic FIR sleeping mat, BioMat still has a strong reputation.

If your main goal is more features for less money, MediCrystal is often the more tempting choice.

I have also owned a Richway Biomat for a few years now, and my family and I love it.

It is highly durable (never had a problem with it for over 5 years), works great, and I often sleep on it all night (in the winter).

Conclusion

MediCrystal mats are most appealing for people who want more than a basic infrared heating pad.

The brand’s biggest strengths are:

• Lots of model choices
• Good size options
• Classic FIR mats for sleeping
• More advanced models with PEMF and red light

The biggest downside is that the feature-rich models are heavier, stiffer, and more expensive, so they are not automatically the best choice for everyone.

If you mainly want comfort, warmth, and overnight use, a simpler classic MediCrystal mat is probably enough.

If you specifically want PEMF and red-light features, then the more advanced collections may be worth the extra cost.

To your health and happiness,

Meital
