Abstract
A seat assembly includes a cushioned component having a lattice matrix, wherein the lattice matrix includes a first portion defined by a first pattern of interconnected links which defines a first set of cells, and a second portion defined by a second pattern of interconnected links which defines a second set of cells. The first portion of the lattice matrix includes a density profile that is different than a density profile of the second portion of the lattice matrix. An air bladder is disposed within a core portion of the lattice matrix and includes a non-porous outer casing surrounding an interior cavity. The outer casing of the air bladder and the lattice matrix are integrated components comprised of a common material to define a monolithic structure created using an additive manufacturing process.
