Abstract
A cushion or bathtub mat includes a pair of contiguous layers each with a repeating pattern of upstanding straight walls forming upstanding cells with upstanding openings between the walls. The repeating patterns of the pair of layers are laterally offset with respect to one another to form a dual layer offset honeycomb. The walls are flexible to buckle into the openings of the cells under a compressive force, and resilient to return to an original upstanding orientation, while having at least a strength to be self-supporting.
Claims20
A cushion device, comprising:
- a) a pair of contiguous layers each with a repeating pattern of upstanding straight walls forming upstanding cells with upstanding openings between the walls;
- b) the repeating patterns of the pair of layers being laterally offset with respect to one another;
- c) the openings in the pair of layers being open with respect to each other to form common openings through the pair of layers;
- d) the cells of the pair of layers being commonly oriented;
- e) the walls of one of the pair of layers extending into the openings of the cells of the other of the pair of layers;
- and
- f) the walls being flexible to buckle into the openings of the cells under a compressive force and resilient to return to an original upstanding orientation, the walls having at least a strength to be self-supporting.

A cushion device, comprising:
- a) a pair of contiguous layers including an intermediate layer and a lower layer, each with a repeating pattern of upstanding straight walls forming upstanding cells with upstanding openings between the walls;
- b) the repeating patterns of the pair of layers being laterally offset with respect to one another so that the pair of layers form a dual layer offset honeycomb;
- c) the openings in the pair of layers being open with respect to each other to form common openings through the pair of layers;
- d) the cells of the pair of layers being commonly oriented;
- e) the walls of one of the pair of layers extending into the openings of the cells of the other of the pair of layers;
- f) the walls being flexible to buckle into the openings of the cells under a compressive force and resilient to return to an original upstanding orientation, the walls having at least a strength to be self-supporting;
- g) a top layer contiguous with the walls of the intermediate layer;
- h) a plurality of openings formed in the top layer aligned with the walls of the lower layer;
- i) a perimeter portion extending around at least a portion of the pair of layers;
- j) the perimeter portion having a substantially continuous layer contiguous with the top layer and traversing a thickness of the pair of layers;
- k) the lower layer extending into the perimeter portion with the walls of the lower layer extending to the substantially continuous layer;
- l) the walls being formed of an elastomer gel with a density less than or equal to water so that the layers have at least a neutral buoyancy;
- and
- m) suction cups coupled to the lower layer to secure the pair of layers to a surface.
