How do Ereada® mats compare (similarities and differences) to the Richway Bio mat?

Both brands are manufactured in Korea — Richway by Richway & Life and Ereada® by Hyundai Co. Both are generally considered superior to many mats manufactured in China.

Ereada® mats are heavier and typically contain about 20–25% more crystals than many mats of the same size, which supports stronger far-infrared (FIR) radiation. Richway Biomats, however, tend to heat up faster (about 30 minutes versus approximately 45 minutes for Ereada® under a thick blanket) while reaching the same maximum temperature of 158°F (70°C), shown as Level 7 on the controller.

Both brands offer 7–8 adjustable heat levels, covering approximately 86–158°F (30–70°C).

Classic Brown Mats

Classic Ereada® Brown mats, produced in Korea for nearly 20 years, are functionally very similar to Richway Biomats.

Both Richway and Ereada® Brown mats feature a Negative Potential (NP) system:

Richway calls this feature EDNI (Electrical Discharge of Negative Ions)
Ereada® refers to it as N.P. (Negative Potential)

N.P. is included on:

Ereada® Brown and Gemstone Mini mats with large controllers
All Ereada® Brown mats Midsize (24"×59") and larger
Richway Biomats Professional size and larger

Richway Mini Biomats do not include EDNI. They are made with a 50% amethyst / 50% tourmaline blend, while Ereada® Mini mats use 100% natural amethyst. Richway uses pure amethyst only in Professional and larger mats.

Product Range

Richway offers a single product line with four sizes and does not offer a midsize 24"×59" option.

Ereada®, in addition to the Classic Brown collection, offers two newer lines:

Purple Ereada® Amethyst mats
Gemstone Ereada® mats

Richway’s EDNI system is marketed at approximately 700V, compared to 600V for Ereada® Brown mats.

Additional Features (Ereada®)

Purple Ereada® mats include additional functions:

660 nm red-light Photon LEDs
Static (permanent) magnets
PEMF (on Compact Pro and larger sizes)
Air-ion function

Gemstone Ereada® mats feature blended natural stones (amethyst, agate, green chalcedony, garnet) and tourmaline ceramic microspheres. Midsize and larger Gemstone mats include PEMF and Air-Ion functions.

The 660 nm red-light function is commonly associated with skin-care and cosmetic applications.

Market Presence

Richway is a well-established brand in the U.S. with about 20 years of market history. Ereada® mats were historically sold mainly to professionals in Asian markets and have been offered directly to consumers internationally for the past few years.

Richway Biomats are widely referenced in books and studies related to FIR technology. Ereada® mats are now sold direct-to-consumer, allowing significantly lower pricing compared to Richway products, which are often sold through distributors or MLM networks.

Materials & Design

Richway Single, Queen, and King Biomats use a plastic film top layer.

All Brown Ereada® mats use a soft artificial suede top layer with heat-stable ultrasonic bonding. The crystal windows are not stitched and do not deteriorate or allow stones to fall out.

Purple and Gemstone Ereada® mats use a more permeable mesh fabric top layer. While slightly firmer than suede, all Ereada® mats are shipped with:

a multilayer 3-D Air Mesh cushioned protector
a thinner waterproof fleece cover

Warranty & Service

Ereada® mats include a 1-year full warranty and lifetime service support.

Richway markets a “3-year warranty,” but in practice this includes:

1 year of free warranty service
2 additional years of paid after-warranty service

For Ereada® warranty replacements, customers do not pay return or replacement shipping, even though mats are heavy. Richway’s warranty terms indicate that shipping fees may apply after the initial warranty period.

Summary

Ereada® and Richway are both high-quality Korean-made products with comparable core functions. Customers familiar with the Richway Biomat can expect a very similar experience from Classic Brown Ereada® mats, with additional feature options available in the Purple and Gemstone collections.
