Richway - King Size Biomat 7000MX 78"x73"

The Richway King Size Amethyst BioMat 7000MX is very similar to other full-body size BioMats. It has the same range of temperatures, internal layers, design, and materials. And like the Queen Size version of the BioMat, The King Size includes two heat zones, so that each person is comfortable at the level they choose.
We usually recommend the Professional Size over the King Size. This is because it can give the same treatment, it is more portable, and it has a lower cost. Even for two people, it may be a good idea to start with the Professional Size BioMat. This way, there is time to make sure both people love using the BioMat, and time to decide whether to trade-up for the King Size, or simply share the BioMat Professional, or get another BioMat Professional.
For overnight use, we recommend the quantum energy pad accessory.
The King-Size BioMat includes these accessories:
Zipper Storage Bag
Fitted Cotton Cover (machine washable)
7000MX Control Box
Documentation and RI#
For overnight use, we highly recommend the quantum energy pad accessory.
