A 3-function electric bed provides three primary adjustable features: height, backrest, and leg rest positions. These beds are designed for patients in hospitals, clinics, or home care settings, offering comfort and improved care by facilitating adjustments for different needs, such as positioning during medical procedures or recovery. 
The 3 functions explained :
Height Adjustment:
The bed frame can be raised and lowered using the remote or control panel, making it easier for caregivers to access the patient, especially for elderly or immobile individuals. 
Backrest Elevation:
The backrest can be adjusted to various angles, enabling patients to sit up, lie down, or adopt a semi-Fowler's position, which is beneficial for breathing and digestion. 
Leg Rest Elevation:
The leg rest can be raised, providing support for the patient's lower body and potentially reducing pressure on their legs, especially during recovery from surgery or for patients with circulatory problems.
