forming a shell including a first support element defining a first void and a second support element defining a second void, wherein forming the shell includes forming a lower portion of the shell of a first barrier layer defining the first void and the second void;
dispensing a first volume of a foam material in the first void;
dispensing a second volume of the foam material in the second void, the second volume greater than the first volume;
forming a first cavity in the first volume of the foam material;
forming a second cavity in the second volume of the foam material; and
sealing the first cavity and the second cavity, wherein sealing the first cavity and the second cavity includes joining a second barrier layer to the first barrier layer to seal the first support element and the second support element, the first cavity and the second cavity being entirely filled with gas after sealing.
