Super easy to assemble, but you will need 2 people to make it go smoothly. The instructions are lacking, it basically skips a few steps but it pretty easy to figure out. Jut remember that the very bottom legs have a tab on each leg on one side only. Those tabs belong in the back to help the tray from falling out. Overall, it's a nice cage with lots of room. I only wish it sat higher off the ground, but this will make a nice addition to my lanai for when we let the birds have some outside time.
