My cats really loved the rope ball and sisal posts- I ended up getting rid of their old triangle scratching post for this jumbo jungle. I have two cats one 22lbs and the other 12lbs and they both fight over the top sleeping round. My fat cat barely fits but he still gets comfy up on the top! I shopped around a lot to find the exact cat tree for my two furballs and I am very happy with the purchase- took me 20 minutes to set-up.
