The present invention relates to cushioning apparatus having a plurality of intersecting columns, the columns being formed from a thermoplastic, silicone, two-part, or other gel material. The cushioning apparatus are extremely strong and durable yet provide an improved cushioning apparatus. The intersecting columnar configuration of the cushioning apparatus allow for weight to be shared with neighboring column walls. When force is exerted on the columns, the column walls are designed to buckle in the areas of greatest pressure. The column buckling diffuses energy from the areas of highest pressure effectively eliminating pressure points. As the polymer gel collapses within the column walls, the column walls essentially collapse at least partially in a lateral direction allowing pressure to flow away from the areas of greatest pressure to areas of lesser pressure. This provides an improved cushioning surface on which a user can sit, sleep, or other types of cushioning can be provided.
