An absorbent composite foam is provided having a density below 0.04 g/cc and low wet collapse comprising (i) between about 5 to about 40% by wt. fluid resistant fibers； (ii) between about 30 to about 80% by wt. cellulosic fibers； (iii) between about 5 to about 35% by wt. binder； and (iv) a foaming surfactant. The combination of ultra-low density and wet stability is achieved, despite a high proportion of cellulosic fibers, by having both hydrogen bonding between cellulosic fibers as well as inter-fiber bonds formed by the binder.
