1. A passenger seat comprising:
a seat back;
a seat pan; and
a cushion comprising:
one or more lattice structures, wherein the one or more lattice structures each comprise a triply periodic minimal surface, wherein the triply periodic minimal surface is formed of a plurality of unit cells, wherein the plurality of unit cells are periodic in cylindrical coordinates, wherein the triply periodic minimal surface comprises a cylindrical gyroid, wherein the one or more lattice structures each comprise a polymer, wherein the polymer is an elastomer, wherein the plurality of unit cells are defined by a radius dimension, an angular dimension, a height dimension, a radius repetition, an angular repetition, a height repetition, an inner radius, and a wall thickness, wherein the one or more lattice structures each comprise an indentation load deflection of between 20 and 80 pounds inclusive, wherein the one or more lattice structures is a plurality of lattice structures, wherein the plurality of lattice structures comprises a first set of lattice structures and a second set of lattice structures, wherein the first set of lattice structures each comprise a first outer diameter, wherein the second set of lattice structures each comprise a second outer diameter, wherein the first outer diameter is less than the second outer diameter, wherein the indentation load deflection for the first set of lattice structures is greater than the indentation load deflection for the second set of lattice structures.
