Please note that the wagon comes unassembled, I was a bit worried that the assembly would be difficult, but it's actually very quick and easy You just push the wheels into their respective slots on the frame of the cart. I would recommend having a rubber mallet on hand to help with tapping in the front wheels (with the brakes) into the frame of the cart, since these ones were a bit difficult to push in with just your hands.
Once assembled, the wagon was very sturdy and it rolled across the floor with ease, and the wheels are really big, so I can tell this cart is gonna be able to handle some pretty uneven terrain. The wagon smoothly collapses by pressing the front and back sides towards each other, and it folds into a fairly flat shape, so it'll easily store between shelves or in other tight spaces when not in use. There's also a carry-handle attached to the wagon basket so you can carry the wagon in it's collapsed state, as the wagon itself is not too heavy to handle. Re-opening the wagon cart from it's collapsed state is also very easy.
This collapsible wagon cart is so convenient! I'm gonna be so ready for all my summer parties with this wagon, especially when transferring all 550lbs of my party supplies from my car.
