Multilayer absorbent bodies and methods of making the same are disclosed. A method of forming an absorbent body may include: moving a first cover material in a longitudinal direction; moving a reinforcing material in the longitudinal direction and bonding the reinforcing material with the first covering material, the reinforcing material having a top side and a bottom side; applying an absorbent material comprising superabsorbent particles to the top side of the reinforcing material; moving a second cover material in the longitudinal direction, and bonding the second cover material with the first cover material and the reinforcing material to form a laminated structure of the first cover material, the reinforcing material, and the second cover material, in which the first cover material is disposed below the reinforcing material, and the second cover material is disposed below the reinforcing material. The second covering material is arranged on the top of the reinforcing material; and performing embossing on
