Abstract: Mattresses, cushions, and body-support mats or pads are disclosed. Polymer(s) at least partially define a length, width and depth, the depth extending from an upper surface proximate to where a user rests to a lower surface opposite the upper surface. Voids in the polymer traverse at least a portion of the width. The plurality of voids are located at the lower surface and/or the upper surface and are defined by polymer walls and wall(s) of polymer walls define each polymer foot of polymer feet. A first region of a plurality of lower surface regions includes at least one foot of the plurality of polymer feet that has a first size. A second region of the plurality of lower surface regions includes at least one other foot having a second size. The at least one other foot spans a greater distance along the length than the at least one foot.

Abstract: Foam compositions, cushions, and related methods of manufacture are disclosed. The foam composition or cushion includes a polymer that includes about 2% to about 10% polyol comprising multiple hydroxyl groups, about 1% to about 25% isocyanate and about 75% to about 95% filler suspended in the polymer.

Abstract: Foam compositions, cushions, and related methods of manufacture are disclosed. The foam composition or cushion include (a) polymer that includes (i) a maximum of 60% polyol that includes multiple hydroxyl groups, and (ii) less than 50% isocyanate, (b) at least 40% filler suspended in the polymer, and (c) a plurality of digesters suspended in the polymer.

Abstract: Mattresses, cushions, and body-support mats or pads include a plurality of layers extending in a depth direction from a resting surface, where the resting surface is capable of supporting user(s), to a lower surface, the lower surface being opposite the resting surface. The plurality of layers include a comfort layer that forms an upper layer proximate to the resting surface, where the comfort layer includes deformable walls separated by voids and the deformable walls include a plurality of fiber strands embedded in a cushioning media.

Abstract: Body support cushions are disclosed. The cushions comprise a plurality of separate and distinct consecutive layers overlying over each other in a depth direction. Each layer includes thermal effusivity enhancing material with a thermal effusivity greater than or equal to 2,500 Ws0.5/(m2K), and the total thermal effusivity of increases from layer to layer in the depth direction. The plurality of layers include a plurality of phase change layers that each comprise a solid-to-liquid phase change material (PCM) with a phase change temperature within the range of about 6 to about 45 degrees Celsius. The total mass of the PCM increases from layer to layer in the depth direction. At least one layer of the plurality of phase change layers includes a gradient distribution of the mass of the PCM and the amount of the thermal effusivity enhancing material thereof that increases in the depth direction.

Abstract: Body support cushions, such as mattresses, are disclosed. The cushions comprise a plurality of separate and distinct consecutive layers overlying over each other in a depth direction. Each layer includes thermal effusivity enhancing material with a thermal effusivity greater than or equal to 2,500 Ws0.5/(m2K) and a solid-to-liquid phase change material (PCM) with a phase change temperature within the range of about 6 to about 45 degrees Celsius. The total thermal effusivity of each of the cooling layers increases with respect to each other in the depth direction, and the total mass of the PCM of each of the cooling layers increases with respect to each other along the depth direction. At least one layer of the cooling layers includes a gradient distribution of the mass of the PCM and the amount of the thermal effusivity enhancing material thereof that increases in the depth direction.
