The present invention provides a method of forming a multistrata absorbent structure, comprising: a) airlaying a 1st batt of fibers to be used in fluid distribution; b) airlaying a 2nd batt of fibers and a high absorbency material to be used in fluid storage over the 1st batt of fibers; c) airlaying a 3rd batt of fibers to be used in fluid acquisition over the 2 nd batt of fibers; and d) compacting the batts of fibers to form a multistrata absorbent structure comprising a fluid storage stratum between an acquisition stratum and a distribution stratum.
