Description
Overview
The HealthyLine Rainbow Mat 74″ × 28″ is the largest Rainbow series mat, a flat heated surface made of seven natural gemstones — amethyst, sodalite, blue lace agate, green aventurine, yellow aventurine, carnelian and red jasper. A dial controller sets the far infrared heat up to 158°F (70°C), and a built-in PEMF (pulsed electromagnetic field) system with 6 coils runs at 7.83 Hz.
At 74 × 28 × 1.2 inches it has the same dimensions as HealthyLine’s professional models, so it fits a standard massage table as well as a bed or floor, and HealthyLine sizes it for people of any height. It weighs 40 lb. This listing is the 220–240V European version: it has a European plug, draws 250 watts and comes with a 30-day limited warranty.

Things to consider
- It has a European plug, so check it suits your sockets. It will not run from a standard US 110V outlet: HealthyLine says a plug adapter is not enough and a 110V-to-220V step-up converter rated for at least 600 watts is needed.
- At 74 × 28 in and 40 lb it is a large, heavy mat, so plan the floor or bed space to lay it flat and somewhere to store it.
- HealthyLine’s safety FAQ for its mats: with a pacemaker, consult your doctor first (then use it with PEMF off and on low heat), and take care if pregnant or trying to become pregnant. Its listed contraindications include varicose veins, open wounds or thin skin, bypass surgery, muscle relaxants, blood thinners and reduced skin integrity or temperature sensitivity.
