A hospital bed is a special kind of bed that is used in hospitals to help sick people get better. It's not like a regular bed you might have at home – it can move in lots of different ways to make the patient more comfortable.
One big trick of a hospital bed is that it can be raised and lowered with special controls so that doctors and nurses can get to the patient more easily. They can also adjust the bed so that the patient is lying down flat, or sitting up at an angle if that's more comfortable. This can be really helpful if the patient has trouble breathing or needs to eat or drink lying down.
Another thing that's different about a hospital bed is that it has rails on the sides to help keep the patient safe. These can be moved up or down depending on what the patient needs. Sometimes a patient might have trouble moving around by themselves, so hospital beds can also have buttons that can move the bed to help a person get into a better position.
Overall, a hospital bed is a pretty special thing that can make a sick person feel a lot better while they're in the hospital. It lets doctors and nurses take care of them better and keeps them safe while they're resting and recovering.
