One of the primary functions of foam in hospital beds is pressure distribution. When patients are confined to a bed for long durations, they are at risk of developing pressure ulcers, commonly known as bedsores. These injuries occur when blood flow to the skin is restricted due to prolonged pressure. High-quality foam mattresses are designed to redistribute body weight evenly, minimizing pressure points and reducing the risk of skin breakdown. Various types of foam—such as memory foam, latex, and gel—are employed depending on the patient's specific comfort and medical requirements.
