A method of forming an iso-grid structure may include filling multiple pockets of the iso-grid structure with a filler material, attaching a support structure to the perimeter of the iso-grid structure, shaping the iso-grid and support structures, and removing the support structure from the iso-grid structure. The support structure may be thinned and stretched during the shaping process.

A molded flexible polyurethane foam having a hardness gradient going from soft to hard from the top to the bottom of the foam. The hardness gradient in the foam is a result of a foam elasticity gradient which arises from a polymer elasticity gradient and/or density gradient. A method for producing a flexible foam having a hardness gradient and a reactive mixture suitable for making said flexible foam is disclosed. Furthermore, the use of the flexible foams having a hardness gradient in matrasses, cushions for seating (more in particular for use in automotive seating), furniture, automotive under-carpets and dash insulators is disclosed.
