Superabsorbent-containing composites containing at least one particle of a superabsorbent material covered with at least a first layer of at least one particle of at least one coating material. The superabsorbent materials are desirably stiff-gelling superabsorbent materials. The superabsorbent-containing composites of the present invention are particularly suitable for use in sanitary napkins, diapers and other disposable absorbent articles that handle complex fluids.
