Don’t use an electric adjustable bed.
Healthy HouseTM TechTip
Adjustable beds with an electric motor typically create elevated magnetic and electric fields. When plugged into the wall, many electric adjustable beds are in the extreme level of concern range according to Building Biology safety standards. As electric field strength increases, so does your body voltage.
It is best to avoid purchasing any bed or bedframe that plugs into the wall including those with features such as massage, warming, and USB charging. If you already own one of these types of electrical-powered beds, it is best to unplug it before falling asleep.
