A cushion for a school bus seat, comprising: a single piece of skinned foam including foam and a skin integrally bonded to the foam, the single piece of skinned foam including a top, bottom, front, back, first side, and second side, wherein the first and second sides are at opposing ends of the single piece of skinned foam; anda cavity in a mid-region of the single piece of skinned foam and configured to receive a substantially upright back portion of a school bus seat frame,wherein the cavity provides an opening in the bottom of the single piece of skinned foam;wherein the opening extends horizontally from the first side of the single piece of skinned foam to the second side of the single piece of skinned foam, and extends vertically upwards into the single piece of skinned foam, while remaining substantially surrounded by the top, front, back, and first and second sides of the single piece of skinned foam;wherein the single piece of skinned foam and cavity are configured to receive the substantially upright back portion upon insertion of the substantially upright back portion into the opening and sliding of the single piece of skinned foam over the substantially upright back portion; andwherein the single piece of skinned foam is configured to provide an envelope structure so as to provide energy absorption on the front, back, and first and second sides, andwherein the single piece of skinned foam comprises at least one outward extending portion configured to compartmentalize and contain passengers, the at least one outward extending portion being at least one of: (i) a side barrier extending outward in a frontward direction relative to the front side of the single piece of skinned foam, wherein the side barrier comprises outer and inner opposing surfaces, wherein the side barrier extends in the frontward direction relative to the front side a distance that is greater than a width extending between the outer and inner opposing faces of the side barrier, and wherein the side barrier is configured and extends sufficiently in the frontward direction relative to the front side to bar passengers from being thrown from the seat during an off-camber collision, and(ii) an outward extending curvature extending in a rearward direction relative to the back side of the single piece of skinned foam, wherein the outward extending curvature is curved such that a lower portion of the outward extending curvature extends farther rearward than an upper portion of the outward extending curvature, wherein the outward extending portion is configured to extend across the back side along a width of the back side, and wherein the outward extending curvature is configured and extends sufficiently in the rearward direction relative to the back side to compartmentalize and contain passengers seated directly behind the outward extending curvature and reduce injuries during a rollover. 2. The cushion for a school bus seat of claim 1, wherein the single piece of skinned foam comprises the side barrier, without the outward extending curvature. 3. The cushion for a school bus seat of claim 1, wherein the single piece of skinned foam comprises the outward extending curvature, without the side barrier. 4. The cushion for a school bus seat of claim 1, wherein the single piece of skinned foam comprises both the side barrier and the outward extending curvature. 5.
