A wagon is adjustable between a collapsed configuration, an intermediate configuration, and an expanded configuration. The frame has a vertical pole assembly arranged at each of the four corners of the frame. Each of the vertical pole assemblies comprises an extension member telescopically arranged with a fixed member and a slider operatively slidingly connected with the fixed member. When the frame is altered from the expanded configuration to the intermediate configuration, the slider of each vertical pole assembly moves away from the distal end of the fixed member toward the proximal end of the fixed member and the extension member moves from the raised position to the lowered position. When the frame is altered from the intermediate configuration to the collapsed configuration, the extension member moves from the lowered position to the raised position with the slider at or adjacent to the proximal end of the fixed member.
