Problems solved by technology

However, such pillow configurations are only capable of dissipating relatively little heat and/or are uncomfortable for a relatively short period of time.
For example, some of these pillows may actually store heat for a relatively long period o

Abstract

Cushions comprise a plurality of separate and distinct consecutive layers (12) overlying over each other in a depth direction. Each layer (12) includes thermal effusivity enhancing material with a thermal effusivity greater than or equal to 2,500 WsO,5/(m2K), and the total thermal effusivity of increases from layer to layer in the depth direction (D1). The plurality of layers (12) include a plurality of phase change layers (20,22,24) that each comprise a solid-to-liquid phase change material PCM (26) with a phase change temperature within the range of about 6 to about 45 degrees Celsius. The total mass of the PCM (26) increases from layer to layer in the depth direction (D1). At least one layer (20,22,24) of the plurality of phase change layers (12) includes a gradient distribution of the mass of the PCM (26) and the amount of the thermal effusivity enhancing material TEEM (28) thereof that increases in the depth direction (D1).
