Imperial Strom® provides you with an anti-rheumatic mattress made by copper and coal, which constitutes a ground-breaking invention in mattress construction. Copper’s beneficial effect has been widespread since Hippocratic age. They were detected initially in slaves. Notwithstanding that they were working for whole day under hard conditions and in a humid environment, they did not appear problems related to rheumatopathy or arthritic deficits, because they were in chains. And this is the reason why, copper chains around their hands and their feet were protecting them from those diseases. Later, magnetic fields were the main subject matter of research for Leonardo Da Vinci, too. A mattress like that will constitute the natural system, which will defeat stress, fatigue, migraines, insomnia and rheumatic pains.
