Here are two primary functions of many standard hospital beds:

1. Adjustable Headrest:
   • Function: Allows the upper part of the bed, where the patient’s head rests, to be raised or lowered.
   • Purpose: Useful for patients who need to be in a semi-upright position to eat, communicate, or simply for comfort. Elevating the head can also help with respiratory issues or acid reflux.
2. Adjustable Footrest:
   • Function: Enables the lower portion of the bed, where the patient’s feet are, to be raised or lowered.
   • Purpose: Beneficial for patients who need leg elevation to reduce swelling or enhance circulation. It can also be used to adjust the bed to a position where the patient’s feet are flat on the bed, and the knees are bent, which can be more comfortable for some individuals.

Besides these two primary functions, more advanced hospital beds may also offer additional features like adjustable bed height, lateral tilting, integrated weighing scales, and electronic control panels.
