The incontinence underpads have a quilted top sheet that provides comfort. The super-absorbent core soaks up fluids to help eliminate odors. The blue backsheet is waterproof to protect surfaces from leaks. Adhesive strips prevent these underpads from slipping. The 30 x 36-inch underpads don't contain latex which might cause adverse reactions. The perimeter seal on the disposable bed pads is large to prevent leaks.
