Booster for the head of a bed

Raising the bed is intended to provide an answer to a person in a home bed, having difficulty sitting on his own, or having to sleep with a raised pillow.
The elevation allows the patient to raise his head up to the desired height, in order to relieve him while eating, drinking, and so on.
In some models you can adjust the desired angle, up to 90 degrees. The image for illustrative purposes only
