A seat adapter removably mounts a child seat to a wagon having two opposing walls and an interposed connecting wall, and includes two latch components that mount to the wagon's opposing walls. In some embodiments, the seat adapter includes a cross-member extending between the latch components so that the cross-member provides structural integrity to the wagon if the connecting wall is displaced from its upright use position. In some embodiments, the seat adapter and the child seat can be mounted to the wagon for use with the connecting wall in its upright use position, and in some embodiments the seat adapter and the child seat can be mounted to the wagon for use whether the connecting wall is in its upright use position or its displaced position, with no mechanical interference between any part of the wagon and any part of the adapter or the child seat mounted to it.

A seat adapter assembly rigidly mounted to two opposing upright walls of a wagon for mounting a child seat, the seat adapter assembly comprising: a first adapter-to-wagon latch component configured to removably mount to a first upright wall of the two opposing upright walls of the wagon;a second adapter-to-wagon latch component configured to removably mount to a second upright wall of the two opposing upright walls of the wagon;a first adapter-to-seat latch component extending out of the first adapter-to-wagon latch component and configured to removably attach to the child seat; anda second adapter-to-seat latch component extending out of the second adapter-to-wagon latch component and configured to removably attach to the child seat. 3. The seat adapter of claim 1, wherein a displaceable wall is movable between an upright position for use and a displaced position for storage, wherein in the displaced storage position the wall vacates a space in which the child seat is mountable in an outboard position with at least a portion of the child seat extending beyond the wall upright use position. 4. The seat adapter assembly of claim 2, wherein the wagon further has an upright connecting wall interposed between the opposing walls, wherein the child seat mounts to the first and second adapter-to-seat latch components with no interference with any part of the wagon including the upright connecting wall. 5. The seat adapter assembly of claim 4, further comprising vertical extension members extending between the first and second adapter-to-wagon latch components and the first and second adapter-to-seat latch components to elevate the adapter-to-seat latch components higher than the upright connecting wall. 6. The seat adapter of claim 1, further comprising a plurality of latch interface sets each including a different design of the adapter-to-seat latch components selected for a different design of the child seat and each including a coupling part that couples to a cooperating coupling part of a respective one of the adapter-to-wagon latch components, wherein the latch interface sets interchangeably mount to the seat adapter to enable the seat adapter to be used with the different designs of the child seat. 7. The seat adapter of claim 1, wherein the child seat is selected from the group consisting of an upright car seat, an infant carrier seat, and a stroller seat. 8. The seat adapter of claim 1, wherein multiple different designs of the child seat can be interchangeably mounted in place to the wagon by the seat adapter. 9. The seat adapter of claim 1, wherein the wagon further has a displaceable connecting wall interposed between the two opposing walls and releasably secured in an upright use position to the opposing walls at wall latch components of the opposing walls, wherein the adapter-to-wagon latch components of the adapter removably mount to the wall latch components of the opposing walls when the displaceable connecting wall is displaced from the upright use position. 10. A seat adapter for mounting a child seat to a wagon having two opposing upright walls and a displaceable connecting wall interposed between the opposing walls, the adapter comprising: two adapter-to-wagon latch components configured to removably mount to the wagon opposing walls;two adapter-to-seat latch components extending from the two adapter-to-wagon latch components and configured to be removably mounted to by the child seat; anda structural cross-member extending between the two adapter-to-wagon latch components to provide structural support to the wagon,wherein the child seat mounts to the adapter-to-seat latch components with no interference with any part of the wagon when the displaceable wall is displaced from an upright use position to a displaced position for storage, wherein in the displaced storage position the wall vacates a space in which the child seat is mountable in an outboard position with at least a portion of the child seat extending beyond the wall upright use position, wherein the seat adapter mounts to the wagon to position a bottom of the child seat below a top of the opposing walls for stability, and wherein the structural cross-member provides the structural strength lost by displacing the displaced wall. 11. The seat adapter of claim 10, wherein the seat adapter further mounts to the wagon and the child seat mounts to the seat adapter with the connecting wall in the upright use position with the child seat not interfering with any part of the seat adapter or any part of the wagon including the upright connecting wall. 12. The seat adapter of claim 11, further comprising vertical extension members extending between the adapter-to-wagon latch components and the adapter-to-seat latch components to elevate the adapter-to-seat latch components higher than the upright connecting wall. 13. The seat adapter of claim 10, further comprising one or more obstruction members extending downward from the structural cross-member to comply with ASTM F833-15 Section 6.10 for safety. 14. The seat adapter of claim 10, further comprising a plurality of latch interface sets each including a different design of the adapter-to-seat latch components selected for a different design of the child seat and each including a coupling part that couples to a cooperating coupling part of a respective one of the adapter-to-wagon latch components, wherein the latch interface sets interchangeably mount to the seat adapter to enable the seat adapter to be used with the different designs of the child seat, wherein multiple different designs of the child seat can be interchangeably mounted in place to the wagon by the seat adapter. 15.
