A five-function home hospital bed has fiveadjustments. They are typically head (or back), foot, height, Trendelenburg and reverse Trendelenburg adjustments. Standard consumer beds are fixed platforms, parallel to the floor, and locked in at a certain height. Adjustable beds, in contrast, feature mechanisms that allow occupants and caregivers to modify the bed's shape, height, and even the angle of the bed's surface. Adjustable bed manufacturers and retailers categorize home hospital beds according to the number and type of adjustments. We discussed in an earlier article how beds are categorized according to the way their adjustments are powered: manual, semi-electric, and fully electric. In this article, we're going to look at another way that you will often see beds advertised.
