Beds designed with one or more mechanisms operated by manual crank handles or other controls that can be operated by the patient or staff members to adjust the bed surface, contour, or both. In most mechanical beds, the mattress support is divided into three or more pivoted sections that can adjust the height and assume Gatch positions or Fowler positions (head and knees elevated) or tilt to Trendelenburg and reverse Trendelenburg positions (body straight; feet elevated or lowered, respectively). Most mechanical beds include movable and latchable siderails. Some beds may incorporate fixed endrails or a fabric framed canopy. Mechanical beds are mainly used in healthcare facilities (e.g., hospitals, nursing homes) and at home for resting and sleeping and also during recuperation and/or medical treatments (e.g., alternating pressure) and procedures (e.g., birthing, radiography).
