Infrared gemstone mats come in many sizes and styles, and the product names can blur together. PHYMAT sells a range of them, from full-length mats with PEMF to small pads you can put on a chair, and the right pick depends on how you plan to use it.
This guide goes through the PHYMAT range using the details and prices shown on the brand’s website on 26 October 2026, with the aim of helping you narrow the choice down by size, stones, extra features and voltage. Descriptions of benefits come from the brand’s own product pages, and this is not medical advice.
In this guide
Start With the Size
The first decision is how much of your body the mat needs to cover. PHYMAT lists these main formats:
- Full-length (about 67 to 71 inches): the PEMF mats and the Photon mat, designed for lying down on a bed, floor or massage table.
- Soft full-body (59 x 24 inches): the bendable gemstone mat that the brand says can be used on a bed, chair or recliner and rolled up for storage.
- Medium and small (24 to 37 inches): the Rainbow Chakra and Red Light Hot Stone mats, plus the mini mat at roughly 18 x 18 inches.
If you are tall, look at the Amethyst PEMF Mat Pro. The brand lists it at 70.9 x 31.5 inches (180 x 80 cm) and says it suits a standard massage table and taller people.

The Full-Length PEMF Mats
The Amethyst Infrared PEMF Mat Pro is the flagship. The brand describes four therapies in one: far infrared heat, PEMF, negative ions and healing crystals. About 90 percent of the mat is infused with amethyst, and the upper portion is filled with obsidian, turquoise, yellow agate and red agate.
The 5-Gems Infrared PEMF Mat Single is a shorter alternative at 66.9 x 27.6 inches. The brand says it uses five types of untreated natural gemstones in a thick layer under the mesh fabric, and it is listed for whole-body use.
The Photon Infrared PEMF Therapy Mat adds red light. PHYMAT lists it as a five-in-one mat combining PEMF, far infrared, red light, negative ions and gemstone heat, with 133 stones in total: 70 natural agates, 63 ceramic tourmaline stones and 12 photon LEDs.
Smaller and Softer Options
Not everyone needs a full-length mat. The soft Infrared Gemstone Heat Therapy Mat is described by the brand as bendable, so it can sit on a bed, chair or recliner, wrap around a body part and roll up for storage. It uses green aventurine, clear crystal, amethyst, obsidian and tourmaline.
The Rainbow Chakra mat is built around seven kinds of natural gemstones, jade and tourmaline. PHYMAT says the smaller sizes can be used as a seat warmer on an office chair, and that the mat rolls into a storage bag for travel.
For a single area, the Purple Mini mat measures 17.7 x 17.7 inches and is meant for target areas such as the lower back, stomach, hands or legs, according to the brand.
The Red Light Hot Stone mat comes in three sizes, from 23.6 x 15.7 inches up to 37.4 x 21.7 inches. It pairs jade and tourmaline stones with far infrared, negative ions and red light, and the mini size is described as flexible enough to wrap around a body part.
Check the Voltage Before You Order
Many PHYMAT mats are sold in separate 110V and 220V versions, and the Rainbow mat variants are labelled for USA and Canada (110V-120V) or the rest of the world (220V-240V). Choose the version that matches the sockets where you will use the mat, because the listing is split by voltage.
Covers and Controllers
PHYMAT also sells a waterproof quilted cover for heated stone mats. It is made of cotton, machine washable and secured with elastic, and it comes in three sizes: 59.1 x 23.6 inches at USD 44.99, 66.9 x 27.6 inches at USD 49.99 and 70.9 x 31.5 inches at USD 54.99. A Replacement Smart Controller was listed at USD 39.99. Note that the brand says the cover does not include a controller.
Which One Should You Pick?
- For lying down at full length: the Amethyst PEMF Mat Pro if you are tall, otherwise the 5-Gems or Photon mat.
- If you want red light as well: the Photon mat or the Red Light Hot Stone mat.
- For a bed, chair or travel: the soft bendable mat or the Rainbow mat.
- For a small area or a desk chair: the Purple Mini or a small Rainbow size.
- On a tighter budget: the mini and smaller mats start from about USD 127 to USD 136.
Because these are heated devices, read the safety instructions that come with the mat and speak with a healthcare professional before use if you have a medical condition or an implanted medical device. Full specifications and reviews are on the PHYMAT product pages.
