Dependent claims

A cellular structure comprising:

a plurality of vertically stacked textile layers, wherein at least N number (N>1) of each of said stacked textile layers comprise:
an array of intersecting structural support members forming apertures of predetermined geometric configurations, wherein each of said predetermined geometric apertures are vertically aligned with respective apertures of corresponding immediate adjacent textile layers;
said textile layers having a top side and a bottom side;
said textile layers having a perimeter with at least three perimeter sides;
wherein:
at least a portion of said top side of each of said textile layers for the first through (Nth−1) layers comprise a top adjoining region;
at least a portion of said bottom side of each of said textile layers for the second through (Nth) layers comprise a bottom adjoining region;
and
wherein each of said textile layers are discretely bonded at selected points of contact to immediate adjacent textile layers, wherein said discrete bonds are formed:
between said top adjoining region and said bottom adjoining region, and
using a material distinct from materials used to make said immediate adjacent textile layers.
