One of the primary functions of a patient bed is to provide comfort to individuals who may be experiencing pain or discomfort due to illness, injury, or surgery. Hospitals frequently see patients with diverse medical conditions; therefore, the design of patient beds must accommodate a wide range of needs. For instance, adjustable beds allow for modifications in height and position, making it easier for patients to find a comfortable posture. This adjustability is particularly beneficial for patients recovering from surgery, as it can alleviate pressure on incisions and other sensitive areas of the body.
