This tree came in one large box with one page of instructions and no words. It was daunting at first but with a few minutes of laying out the pieces it was super easy to assemble. The tree is very sturdy and the cats love it. One thing - It's not meant for large cats. One of my cats can only really lay at the top two sections because she doesn't fit anywhere else. However it's of good quality and would be perfect for kittens or smaller cats.
