Are Ereada® mats grounded?

Yes, all Korean mats are grounded. They include a special network of wires within the charcoal layer designed to capture stray electrical waves and direct them to the ground pin of the wall outlet.

While this feature is less critical with modern low-EMF heating systems, grounding is still beneficial because it provides a connection to the earth while you lie on the mat. In everyday life, we often lack this natural grounding due to wearing insulated footwear such as rubber boots or sneakers. The mat helps restore that connection by allowing grounding through the electrical system.
