摘要： A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.
