A heating and cooling device includes a thermoelectric module that is configured to move heat to or from a conductive surface thereof in response to low voltage power applied to the thermoelectric module. A composite structure is configured to conductively transfer heat between the thermoelectric module and the body. The composite structure includes a graphene sheet material that has an interfacing portion that is thermally coupled with and overlaying the conductive surface of the thermoelectric module. A high thermal conductivity isotropic cladding is disposed at least partially over an outlying portion of the graphene sheet material outside of the interfacing portion. The isotropic cladding conductively transfers heat in a direction orthogonal to a planar extent of the graphene sheet material with a higher thermal conductively than the graphene sheet material in this direction.

A fertility-enhancing cooling seat for lowering temperatures of human testicles so as to increase sperm quality and quantity. The cooling seat includes: a top flexible portion and a base portion; a bottom flexible portion coupled to the top flexible portion, the bottom flexible portion forming a seal with the base portion, portions of the bottom flexible portion and portions of the top flexible portion defining isolated cooling cells with cooling-cell volumetric spaces; a phase-change material located in the cooling-cell volumetric spaces, the phase-change material configured to change from a solid phase to a liquid phase at a first temperature and that is configured to change from a liquid phase to a solid phase at a second temperature that is lower than the first temperature. At least one of the isolated cooling cells defines a diameter that is larger than a diameter of the other of the cooling cells.

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 Ws.sup.0.5/(m.sup.2K), 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.

A foam padding (10) is disclosed. The foam padding (10) has sections (32, 34), each covering at least one hollow volume (12, 14) of the padding said padding (10) including a flexible elongated band (20) for transferring thermal energy from at least one hollow volume (12) in a first one of said sections (32) in the event of excess thermal energy towards at least one hollow volume (14) in a second section (34) in the padding (10) not containing excess thermal energy. The band (20) has a continuous electrically conducting layer (22) with a defined area extending from at least one first section (32) to another different second section (34).

A cushion having a foam core sandwiched by opposing gel infused viscoelastic pads adhesively attached to the core, the assembly wrapped in a non-woven and received in an upholstery casing, for seating use of the cushion in a furniture piece that during use for seating, the upper one of the pads wicking body heat into the seating cushion away from the person sitting thereon to provide a perception of cooling and the compressed pad readily reboundable to a noncompressed state after occupancy, and the cushion rotatable to selectively alternate the seating pad for use.

Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided. Electrical systems for use in the powered chairs, and components for use in the electrical systems are provided. Control systems and methods for operating powered chairs are also provided. Any given chair may be locally and/or remotely controlled.

Embodiments of the invention relate to a cushion apparatus comprising a resilient spring member. Typically, the cushion apparatus in configured to provide flexible support to a user, allow air circulation through and within the cushion apparatus and allow ventilation of excess heat. In some embodiments, the cushion apparatus comprises a resilient spring member and a cushion cover member at least partially enclosing the spring member. In some embodiments, the cushion cover member is structured to be removable attached to the resilient spring member.

A product and process for reducing discomfort due to heat and moisture evolved during a period of contact between living skin and a cushioning material, using a thermally conductive cushioning device, having a first layer of a moisture management fabric, a second layer of a thermally conductive web, and a third layer of a thermally insulative cushioning material.

The present disclosure relates to a breathable cushion. The cushion includes a thigh support portion, a hip support portion, and a waist and back support portion. The thigh support portion includes a plurality of thigh support structures each having an opening structure; the hip support portion includes a plurality of hip support structures each having an opening structure; and the waist and back support portion includes a plurality of waist and back support structures each having an opening structure. The area of the opening structures of the thigh support structures and/or the area of the opening structures of the waist and back support structures is greater than the area of the opening structures of the hip support structures. The cushion has the following advantages. The cushion has an ergonomic design and structure, and provides reasonable and reliable supports. In addition, the light-weight and highly comfortable cushion has good air permeability.
