Underpads, also known as bed pads or chux, are absorbent sheets designed to protect surfaces from moisture and stains. They are commonly used in healthcare settings, such as hospitals and nursing homes, to keep beds and chairs clean and dry. Made from layers of absorbent material, underpads can help manage incontinence and provide comfort for patients. These pads come in various sizes and absorbency levels, making them suitable for different needs. They can be disposable or washable, offering convenience for caregivers and individuals. Underpads are also used in home settings for pets or during potty training, providing an easy solution for managing spills and accidents.
