HOW DO YOU MEASURE FIRMNESS?
Every company has answered this question differently. Some use hidden decimal points, while other use invented scales. To us, there was never any question: measure like the doctors do. We measure the firmness of our mattresses in mm/Hg (millimeters mercury), the same pressure scale that doctors use when taking blood pressure. We manufacture in a medical-grade FDA approved facility, so the connection was natural, measure firmness like the doctors.While our mattresses do allow you to adjust from 0-50, it is important to note that the human body typically maintains an internal pressure of about 32 mm/Hg, so sleeping at a firmness that exceeds 32 could lead to decreased circulation which would in turn create pressure points and lower overall quality of sleep. note: our mattresses do not contain mercury, to learn more about mm/Hg, click here.
