Infrared and PEMF mats: what to compare
Mats with similar names can have different configurations. The useful comparison begins with what is included in the exact model.

Distinguish heating from PEMF
Infrared heating and a pulsed electromagnetic field option are different features. A supplier using both terms in a title does not confirm that every configuration includes both. Check the ordered specification and avoid treating an optional feature as standard.
Confirm size and electrical configuration
Full-length mats come in several sizes and power editions. Ask for the exact dimensions, power input and model instructions. A product intended for one country should not be assumed to work in another simply because a travel adapter fits.
Look at construction and care
The surface, edge, controller and cleaning instructions tell you how the equipment fits into a home. Treat claims about stones or energy separately from physical product details. Follow instructions and seek qualified advice when suitability is uncertain.
Follow the instructions supplied with the product. No medical outcome is promised.
