         3 . The support cushion of  claim 2 , wherein both the first flexible foam and the second flexible foam are visco-elastic foam, and wherein the first flexible foam has a density greater than the density of the second flexible foam. 
     
     
         4 . The support cushion of  claim 1 , wherein the plurality of flexible foam fragments are comprised of a first portion of flexible foam fragments and a second portion of flexible foam fragments, the first portion of flexible foam fragments having a density greater than the density of the second portion of flexible foam fragments. 
     
     
         5 . The support cushion of  claim 1 , wherein the plurality of fibers are comprised of natural fibers, synthetic fibers, or both. 
     
     
         6 . The support cushion of  claim 1 , wherein the plurality of fibers are comprised of synthetic fibers. 
     
     
         7 . The support cushion of  claim 6 , wherein the plurality of fibers are polyester fibers. 
     
     
         8 . The support cushion of  claim 1 , wherein the filling is comprised of about 50% of the plurality of fibers and about 50% of the first flexible foam. 
     
     
         9 . The support cushion of  claim 4 , wherein the filling is comprised of about 25% of the first portion of flexible foam fragments, about 25% of the second portion of flexible foam fragments, and about 50% of the plurality of fibers. 
     
     
         10 . The support cushion of  claim 1 , further comprising a first amount of phase change material incorporated into the sleeve. 
     
     
         11 . The support cushion of  claim 1 , further comprising a liner surrounding the sleeve. 
     
     
         12 . The support cushion of  claim 11 , wherein the liner includes a second amount of phase change material. 
     
     
         13 . The support cushion of  claim 11 , wherein the liner is comprised of netting. 
     
     
         14 . The support cushion of  claim 11 , wherein the liner is comprised of a flame-retardant material. 
     
     
         15 . The support cushion of  claim 11 , further comprising an outer cover surrounding the liner. 
     
     
         16 . The support cushion of  claim 15 , wherein the outer cover is comprised of a textile. 
     
     
         17 . A pillow, comprising:
 a filling including a plurality of polyester fibers and a plurality of visco-elastic foam fragments;   a sleeve comprised of a visco-elastic foam and encapsulating the filling; and   a liner surrounding the sleeve.   
     
     
         18 . The pillow of  claim 17 , further comprising an outer cover surrounding the liner, the outer cover being comprised of a textile. 
     
     
         19 . A pillow, comprising:
 a filling having a plurality of fibers and a plurality of flexible foam fragments; and   a sleeve encapsulating the filling, the sleeve having at least one surface configured to provide a cooling effect to a user lying on the pillow.   
     
     
         20 . The pillow of  claim 19 , wherein the filling is comprised of about 50% of the plurality of fibers and about 50% of the plurality of flexible foam fragments.
