I assembled the Kitty Mansion per the easy instructions. The key to making this a five star final product is to tighten all pieces correctly. Left loose the tree will not be sturdy! Our assembled cat tree is strong and very sturdy! The design is excellent.  No complaints. All pieces were in the box as described. Our cats are having a ball with it!

Pros: Nice, easy assembly!
Cons: Love the color. Cats tried to eat plastic leaves so they were not installed.
