Side rails are safety features commonly found on beds, especially in hospitals and nursing homes. They are designed to prevent patients from falling out of bed while providing support for getting in and out of bed. Side rails can be adjustable, allowing caregivers to raise or lower them as needed. In addition to their safety function, side rails can also serve as a place to attach items like bedside trays or IV poles. They are typically made of metal or plastic and come in various designs to accommodate different types of beds, including hospital beds and adjustable beds.
