Multi-layered absorbent bodies and methods of manufacture are disclosed. A method of forming an absorbent body may comprise moving a first covering material in a machine direction, moving a reinforcing material in the machine direction and combining the reinforcing material with the first covering material, the reinforcing material having a top side and a bottom side, applying absorbent material comprising superabsorbent particles to the top side of the reinforcing material, moving a second covering material in the machine direction and combining the second covering material with the first covering material and the reinforcing material to form a laminate structure of the first covering material, the reinforcing material, and the second covering material, with the first covering material disposed underneath the reinforcing material and the second covering material disposed on top of the reinforcing material, and embossing the laminate structure.
