Choose from a wide selection of waterproof underpads and bed pads. Underpads are flat absorbent pads that protect on top of upholstery or sheets to reduce linen changes and are available in many sizes and absorbencies. Disposable underpads, often referred to generically as chux, are very popular multipurpose protectors while washable underpads are most popular with family caregivers as they stay in place better than disposable pads and save money over time. Our underpads are also extremely popular for pet owners as training pads or many other uses and provide a big savings over retail puppy pads while providing more options for sizes and absorbencies.
