Beds designed with one or more built-in hydraulic mechanisms and remote controls that can be operated by the patient or staff to adjust the bed surface, contour, or both. In most hydraulic 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 hydraulic beds include movable and latchable siderails. Some beds may incorporate fixed endrails or a fabric framed canopy. Hydraulic beds are mainly used in healthcare facilities (e.g., hospitals, nursing homes) for resting and sleeping and also during recuperation and/or medical treatments (e.g., alternating pressure, birthing) and procedures (e.g., radiography).
