Abstract
A support cushion including a top surface, a bottom surface opposite top surface, a layer of flexible foam having plurality of cells defining a reticulated cellular structure, the reticulated cellular structure cells comprising a skeletal plurality of supports through which substantially open cell walls establish fluid communication between interior of the cell and interiors of adjacent cells, the layer of flexible foam having density no less than about 30 kg/m3 and no greater than about 175 kg/m3, and hardness of no less than about 20 N and no greater than about 150 N at 40% indentation force deflection measured at about 22 degrees Celsius, the layer of flexible foam comprising visco-elastic foam having at least one material property responsive to temperature change in range of 10-30° C., and layer of polyurethane foam located beneath layer of flexible foam, the layer of polyurethane foam having hardness of at least about 50 N.
