Love the cat tree. Its very sturdy for larger cats. I have 2, and one is 18 lbs.  It took awhile to figure out how to put it together as the instructions  are inadequate regarding the post and piece 3 sequence of events .First step needs to be better emphasized. .other we figured that out it went together fairly easy..
Also my cats aren't sure about the basket on the side. Its to wiggly for them to step into .so I ended up putting a piece of cardboard in bottom of it with an old rug piece over it.. its sturdier for them to step into it.. .One of the nicest cat trees I have purchased and well worth the price.
