A foldable wagon configurable in a use configuration and a folded configuration, the foldable wagon comprising:
- a frame that is foldable, wherein the frame comprises:
- a front frame assembly comprising an upper front side assembly;
- a rear frame assembly comprising an upper rear side assembly;
- a center linkage disposed laterally between the front frame assembly and the rear frame assembly;
- an upper pivot bracket disposed between and pivotally connected to the upper front side assembly and the upper rear side assembly;
- a lower pivot bracket;
- a front support assembly;
- a rear support assembly;
- and
- a middle pivot bracket disposed vertically between the upper pivot bracket and the lower pivot bracket, wherein the middle pivot bracket is slidable along the center linkage, wherein the front frame assembly and the rear frame assembly are pivotally connected to the upper pivot bracket, the lower pivot bracket, and the middle pivot bracket, wherein the middle pivot bracket is pivotally connected to the upper front side assembly via the front support assembly and the upper rear side assembly via the rear support assembly.
