The present invention relates to a three-dimensional string woven air cushion and a method of manufacturing the same, the three-dimensional string woven air cushion including a lower sheet layer made by interlacing a plurality of weft yarns and a plurality of warp yarns and configured to define a predetermined thickness layer and a bottom surface, an upper sheet layer made by interlacing a plurality of weft yarns and a plurality of warp yarns and configured to define a predetermined thickness layer and a top surface, the upper sheet layer being disposed above the lower sheet layer, provided in parallel with the lower sheet layer, and spaced apart from the lower sheet layer at a predetermined distance, and an interval maintaining yarn layer made by interlacing interval maintaining yarns connected to at least one of the weft yarn and the warp yarn of each of the lower and upper sheet layers, the interval maintaining yarns being continuously interlaced and connected in a zigzag manner in a direction from one side to the other side, thereby providing an advantage that greatly improve a user’s sleeping convenience.

Methods and combinations of mattress support surfaces comprising one or more flexible polyurethane foam layers containing highly thermally-conductive solids, such as diamond or silicon carbide, and said layer combination is capable of transferring heat from a warm surface, such as a person sleeping on a bed, to a cooler region at a faster rate throughout the mattress than the thermal dissipation rate obtained from flexible polyurethane foam without highly thermally-conductive solids.

A bed sheet is provided that includes a knitted performance fabric having a plurality of spaced apart ventilation ports. The knitted performance fabric has a gauge per square inch, grams per square meter, air permeability and material content that are pre-selected to provide the knitted performance fabric with one or more selected physical features.

A mattress 10 is disclosed. The mattress 10 comprises at least two laminated layers 12, 14. The at least two layers 12, 14 include a first layer 12 defining a support surface 16 configured to support a user, and a second layer 14. The first layer 12 is formed from a resiliently deformable, fluid-impervious material, and defines a plurality of perforations 18 arranged to communicate fluid through the layer 12. The second layer 14 is joined to the first layer 12 to cover an end of at least some of the perforations 18, and is formed from a fluid-pervious material. The second layer 14 is arranged to allow fluid to be communicated between at least some of the perforations 18 and a location external to the second layer 14.

A reversible mattress topper for a mattress is provided that includes opposing first and second panels. A fill material is intermediate the first and second panels. The panel materials and/or selected portions of the filler material will be selected to provide either cooling or comfort for the sleeper. One surface of the reversible mattress topper will be configured to be cooling in nature. The other surface of the reversible mattress will be comforting and optionally warming in nature. The panels can be stylized in order to communicate which surface provides cooling and which surface provides warming.

A temperature modulation system for a bed, blanket, or other furniture includes a fluid for moderating temperature change, a number of conduit circuits for directing the fluid through respective zones, a control unit including a thermoelectric device for modulating temperature of the fluid, and a pump. Each of the conduit circuits selectively and independently directs fluid through its respective zone in order to produce a temperature within the zone that is independent of the temperature outside the zone. The system also includes an arrangement of one or more zones in an arrangement in which the control unit is programmed to vary the zone temperature over time according to a schedule.

A mattress having a three-dimensional elastic structure of the present invention has a structure in which a main elastic body independently contracts and expands by multiple first to fourth auxiliary elastic slits which intersect with each other in left and right directions, front and rear directions, and up and down directions so as to form a three-dimensional air tunnel. Accordingly, when the first to fourth auxiliary elastic slits contract and expand, air is discharged in all directions of the main elastic body through the three-dimensional air tunnel so as to disperse the pressure by a human body, thereby inducing good blood circulation, and heat is released through the three-dimensional air tunnel so as to secure air permeability, thereby inducing maintenance of a proper sleep temperature so as to provide a more comfortable sleep environment.

A three-layered topper fora bedding or seating product has a first piece of foam, a second piece of foam and a pocketed spring comfort layer therebetween. The pocketed spring comfort layer has individually pocketed mini coil springs. At least one of the foam pieces may be infused with metallic particles to improve thermal conductivity. Alternatively, at least one of the foam pieces may be infused with microencapsulated phase change materials to improve heat absorption. At least one of the foam pieces may have a coating to further improve thermal conductivity or heat absorption.

Mattress assemblies including phase change materials and processes for dissipating retained in the mattress assemblies generally include a spacer layer in proximity to one or more foam layers containing a phase change material; and a pump in fluid communication with the spacer layer to provide a positive or negative air flow into the spacer layer to reduce retained heat in the phase change materials subsequent to a sleep cycle. The process includes operating the pump between sleep cycles to reduce the retained heat.

A foam padding has at least one upper section and at least one lower section. The foam padding comprises at least one absorber that is embedded in the upper section, the at least one absorber for absorbing thermal energy from the upper section. The foam padding further comprises at least one band that is embedded in the lower section, the at least one band for transferring thermal energy within the lower section.
