An absorbent article with improved integrity and durability includes a back sheet, a top sheet, and an absorbent core therebetween. The absorbent core passes a tumbling test for products having a total absorption capacity of between 260 g and 800 g, and passes a core resiliency test such that the article has a thickness when compressed laterally and released of less than 7 mm for an article having a total absorption capacity of 260-399 g and 11 mm for an article having a total absorption capacity of 400 g to 800 g. The absorbent core may be airlaid and include two or more layers made from pulp, superabsorbent polymer and/or bicomponent fibers. The various layers and materials create a complex shape retention network. As such, an improved liquid handling structure is created that distributes liquid evenly while maintaining its shape/thinness.
