Abstract
The disclosed technology includes tiered void cells which provide protection, comfort, and stability during compression. The tiered void cells may be arranged in vertically stacked columns and include a stroke whereby tiers of a void cell can telescope into adjacent tiers of that void cell, as well as telescope into adjacent tiers of adjacent void cells in a column. Implementations described and claimed herein include a cushioning system comprising an array of tiered void cells, wherein each tiered void cell includes a base portion, a plunger portion, the plunger portion to collapse into the base portion under compression of the cushioning system, and a living hinge elastically connecting an inner perimeter of the base portion to an outer perimeter of the plunger portion.
