One of the most popular types of hospital bed mattresses is the foam mattress. These mattresses are made from high-density foam, which conforms to the body's shape, providing excellent support and comfort. Foam mattresses are lightweight, easy to handle, and provide sufficient resistance against the sinking effect often experienced in traditional mattresses. Additionally, many foam mattresses come with removable and washable covers, which is a significant advantage for maintaining cleanliness and hygiene.
