A headrest assembly includes a lattice matrix having a plurality of three-dimensional (3D) cells. Each 3D cell of includes a node and a plurality of links outwardly extending from the node. The lattice matrix includes a plurality of sections including a first section having a first overall elastic modulus, a second section positioned adjacent to the first section and having a second overall elastic modulus that is higher than the first overall elastic modulus of the first section, and a third section positioned adjacent to the second section and having a third overall elastic modulus that is higher than the second overall elastic modulus of the second section. The lattice matrix is integrally constructed using an additive manufacturing technique, wherein the 3D cells of each section are provided in various patterns and cured to varying degrees to provide the varying overall elastic moduli of each section of the lattice matrix.
