A bedding article has a fabric having a substrate having a surface area. The fabric has a polymeric material that absorbs and desorbs moisture and/or moisture vapor that results in a catalytic action to actively cool the substrate or fabric. The material covers about 40% to about 70% of the surface area of the substrate and as present on the substrate is present at 0.5 to 1.0 grams per square meter.

A modular multi-component mattress system includes a base layer with a coupling channel, a first reversible support pad assembly with a first side rail and a second side rail, a comfort pad layer, and a cover assembly configured to contain the base layer, the first reversible support pad assembly, and the comfort pad layer. In a first configuration, the first side rail detachably and selectively couples within the coupling channel and the second side rail receives the comfort pad layer. In a second configuration, the first side rail receives the comfort pad layer and the second side rail detachably and selectively couples within the coupling channel. The system includes a second reversible support pad assembly. The system includes a topper layer with a cool comfort side and a warm comfort side. The topper layer detachably and selectively couples with the cover assembly.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. Each string is joined to at least one adjacent string. Each string has first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse segmented seams joining the plies. Gaps between the segments of the seams allow air to pass into and out of the pockets despite the fabric being impermeable to airflow through the fabric. The size of the gaps determines the firmness or feel of the pocketed spring assembly or portion thereof.

Disclosed herein is a system for artificially adjusting effective altitude, including a concentrated gas source and a concentrated gas supply line. The first end of the gas supply line is connected to the concentrated source of gas, and the second end is connected to an air diffuser. The air diffuser can be used as a cover for a pillow or other piece of furniture. The cover includes channels incorporated into the cloth that facilitate transfer of gas from an inlet to one or more diffusion sections. The diffusion sections diffuse the gas into a cloud. When a user's head is placed adjacent to the diffusion section, the user's head is enveloped in the cloud, creating an artificially adjusted altitude.

A bedding system includes an adjustable base comprising a tambour. An air control unit is coupled to the base. The air control unit includes a left fan and a right fan. The fans are positioned under the tambour. A first air passage is connected to the left fan. A second air passage is connected to the right fan. A sealed bag is positioned on the base. The bag includes a spacer and coils positioned therein. The bag includes opposite top and bottom ends. The top and bottom ends are each being breathable. A duct that connects the bottom end to the first and second air passages. A breathable comfort layer is positioned on the bag. A mattress cover is positioned on the comfort layer. Kits and method of use are disclosed.

A support cushion cover assembly for removing humidity and heat from a contact surface of a support cushion is provided. The support cushion cover assembly comprises a support cushion cover that includes an upper panel having a top surface, a bottom surface, and a middle spacer layer positioned between the top surface and the bottom surface. The support cushion cover further includes an amount of hygroscopic material and at least one flexible tube that defines a plurality of fenestrations. Each fenestration is in fluid communication with the middle spacer layer of the upper panel. An air pump is further included in the cover assembly and is operably connected to the flexible tube, such that an amount of air is delivered into the flexible tube and the middle spacer layer of the cover. Methods for removing humidity from a contact surface of a support cushion are also provided.
