Support cushions for providing ventilation

Abstract

A support cushion is provided that includes a core comprised of a first flexible foam and a second flexible foam. Both the first flexible foam and the second flexible foam include a reticulated cellular structure, with the first flexible foam having a density less than the second flexible foam. A sleeve is also included in the support cushion and encapsulates the core.

What is claimed is: 
     
         1 . A support cushion, comprising:
 a core comprised of a first flexible foam including a reticulated cellular structure and a second flexible foam including a reticulated cellular structure, the first flexible foam having a density less than the second flexible foam; and   a sleeve encapsulating the core.   
     
     
         2 . The support cushion of  claim 1 , wherein the first flexible foam, the second flexible foam, or both is a visco-elastic foam. 
     
     
         3 . The support cushion of  claim 1 , wherein the first flexible foam has a density of about 45 kg/m 3  to about 65 kg/m 3 , and wherein the second flexible foam has a density of about 85 kg/m 3 . 
     
     
         4 . The support cushion of  claim 1 , wherein the first flexible foam has a hardness of about 30 N to about 60 N, and wherein the second flexible foam has a hardness of about 60 N to about 90 N. 
     
     
         5 . The support cushion of  claim 1 , wherein the first flexible foam and the second flexible foam are comprised of a plurality of visco-elastic foam fragments. 
     
     
         6 . The support cushion of  claim 1 , wherein the core is a molded foam core. 
     
     
         7 . The support cushion of  claim 1 , wherein the sleeve is comprised of a three-dimensional spacer material having an outer surface, an inner surface, and a middle spacer layer. 
     
     
         8 . The support cushion of  claim 7 , wherein the outer surface of the sleeve defines a plurality of vents. 
     
     
         9 . The support cushion of  claim 1 , wherein the first flexible foam, the second flexible, the sleeve, or a combination thereof includes an amount of phase change material. 
     
     
         10 . The support cushion of  claim 1 , wherein the sleeve is comprised of a flame retardant material. 
     
     
         11 . The support cushion of  claim 1 , further comprising an outer cover surrounding the sleeve. 
     
     
         12 . The support cushion of  claim 11 , wherein the outer cover is comprised of one or more textiles. 
     
     
         13 . The support cushion of  claim 11 , wherein the outer cover includes a first surface and a second surface opposite the first surface, and wherein at least one of the first surface or the second surface includes a central panel surrounded by a border, the border defining a plurality of openings. 
     
     
         14 . The support cushion of  claim 13 , wherein the central panel is comprised of cotton and the border is comprised of polyester. 
     
     
         15 . A pillow, comprising:
 a core comprised of a reticulated visco-elastic foam; and   a sleeve encapsulating the core, the sleeve comprised of a three-dimensional spacer material having a top surface, a bottom surface, and a middle spacer layer.   
     
     
         16 . The pillow of  claim 15 , further comprising an outer cover surrounding the sleeve. 
     
     
         17 . The pillow of  claim 15 , further comprising an amount of phase change material incorporated into the core, the sleeve, or both. 
     
     
         18 . The pillow of  claim 17 , wherein the reticulated visco-elastic foam comprises a plurality of reticulated visco-elastic foam fragments. 
     
     
         19 . A pillow, comprising:
 a sleeve encapsulating a plurality of reticulated visco-elastic foam fragments; and   an outer cover having a first surface and a second surface opposite the first surface, at least one of the first surface or the second surface including a central panel surrounded by a border, the border defining a plurality of openings.   
     
     
         20 . The pillow of  claim 19 , wherein the sleeve is comprised of a three-dimensional spacer material having a top surface, a bottom surface, and a middle spacer layer.
