Abstract
A seat includes one or more cushions secured to a shell. The cushions include a 3D printed lattice of repeating cells. The cells may include nodes interconnected by branches. The nodes may be arranged in a cubic, parallelepiped, diamond, or other arrangement. The branches may extend directly between nodes or may be bent. The branches may extend from each node to an adjacent node that is closest to its point of attachment to the each node or the branches may be curved or bent to secure to a different adjacent node. The 3D printed lattice may include 3D printed barbs formed thereon that engage receptacles in the seat shell. The 3D printed lattice may be printed with a groove that engages a fastening structure on a cover or a separate fastening element. The cover may be a perforated sheet of material or fabric.
