Assembly is a bit tricky. The brackets aren't numbered so you need to sort it out by studying the pictures. If you don't get the angle iron on the post correctly, the pads will swivel and make setting your boat down on the pads unstable. The angle iron has to set over the square post to make it stable. Be careful not to over tighten and bend the metal or lock up the wheels. If you correctly put it together, and inflate the tires, it is a nice cart that holds a 14' Hobie fishing kayak.
